Could be not enough air stones, too much food too early, (over-fed nutrients, need to cut back on baby plants) or too much HEAT in room is my best guess.

pH Problems
If you have a PH problem, you simply did something wrong. You should make sure that the PH of the water going into the tank is very close to 6.0. Anything between 5.8 and 6.8 is OK, but 6.0 works best. When you first set up your tank, you should do a PH test on your water before adding the water to the tank, using the enclosed PH test strips. Then adjust the water with PH UP or PH DOWN before it goes into the tank. That way, the PH perfect nutrients will work best. It can be dangerous to adjust the PH in the tank, especially if you overly adjust it. It is also dangerous to adjust it frequently. A very slight adjustment is OK, but if you change it drastically in the tank by using a large amount of PH UP or PH DOWN, you are taking a big risk of seriously harming your plants. If you do a test on your tank's water and it is extremely out of range from 5.8 to 6.8, then it is best to drain it and replenish it with PH corrected water and nutrients. (see the 8 Step Remedy) Let us repeat, you should add the nutrients to PH perfect water to start with. If you insist on adjusting it in the tank slightly, then use no more than 1/2 level teaspoon of PH UP or PH DOWN to the tank, and no more frequently than 4 hours apart. Plants do not adjust well to rapid changes in PH levels. The results can be Nutritional Lockout. Remember, if you make a mistake then you can easily and rapidly correct it, by using the 8 Step Remedy.
Mixing the Nutrients
We have had growers tell us "when I throw in a packet of nutrients into my tank, they just settle to the bottom and don't dissolve". That is not the proper way to introduce the nutrients and feed your plants. These nutrients are natural elements and not made to perfectly dissolve in water. For example, seashells are not ever going to completely dissolve in water, no matter how much they are pulverized, but are an excellent source of calcium. You should add the packets to a quart jar half full of warm water and stir them rapidly, mixing them as well as possible in the water. Then pour them through a tea strainer or some kind of mesh screen or filter, to filter out the small particles that did not dissolve. Then add the nutrient water mix to the tank.
Always remember when you first start and set up your system, you should start with 1/4 of a packet of GROW nutes, if you are starting with seeds, sprouts or baby seedlings. If you started with clones or baby plants, then start with half a packet of Grow nutes. Your plants should be about 3 inches tall, before you use the nutrients full strength. Then stand back and watch for a growth explosion!
Nutrient and Water Flow
We hear concerns from new growers that the water is not flowing rapidly or strongly from the ends of the tubes into the rockwool cubes. A strong flow is not necessary at all. A slight trickle (bubbling) is all that is needed to keep the rockwool cube moist and the baby roots fed until they reach into the deep water. You do need to check for crimps and folds in the water tubes, especially when you first set up your system.
Keeping It Simple
The biggest mistake that we have seen anyone make starts with "I wonder what will happen if I add miracle nutrients, or cat urine, or molasses" or a dozen other crazy things that we have heard growers try. If you do not know what will happen, don't try it unless you are prepared to start all over because you killed your plants. Experimentation is great, but caution and moderation are the keys to success.
Oxygen Is the Most Important Aspect of Bubbleponics
The best tip we can offer from experience is the importance of air or oxygen in the water. It is not required or necessary for good health of plants, but the addition of a 2nd air stone can make a difference in the speed of growth. You can use a plastic T-coupler so you can add a second stone to the one air pump. You can force growth spurts by draining the tank, waiting five or ten minutes to allow the roots to "air out" and then replenishing the water, even if you add back the same water and nutrient mix that you just drained out. Try it!
There are several ways to drain your tank by the way. One is by adding the drain plug or faucet. Or you can obtain a plastic hose like you can get at the aquarium store to drain your aquarium, and siphon the water out. Another way is to attach the hose to the submersible pump, using your fist as a coupling, and simply allow the pump to pump it out into a bucket.
Diagnosis and Recuperation Guide
We'll discuss some signs of illness first, then offer remedies for Recuperation and Recovery.
Both new leaves and mature leaves are the best indicators to determine how healthy your plants are. Any problem or illness will first manifest itself in the appearance of your leaves. These problems almost always originate from the plant's environment, PH imbalance or over-feeding and under feeding. These problems always result in what is called "nutritional lock-out".
Nutritional Lockout
Allow us to GIVE you a simplified definition of NUTRIONAL LOCKOUT.
Can you imagine sitting a plate before a child at dinner time, with his most favorite food, hot dogs, ketchup and french fries? But also on the plate is a major portion of steamed broccoli, which he is just not fond of and insists on nibbling on. Now imagine telling that child, "you can not eat the hot dog and fries if you do not eat all the broccoli too". NUTRITONAL LOCKOUT is when the child responds with "well then, I just won't eat!"
Stealth-Hydro's nutrients are both nutritionally and PH balanced. But after being in your tank for 5 or 6 days, and being eaten from for 5 or 6 days, they become imbalanced. Perhaps you are growing plants that ate all the nitrogen first and just snacked around the iron, magnesium and calcium, or visa versa. The results are discoloration in the leaves, yellowing or rust spots, or curling up of leaf tips. It also becomes apparent when your plants were consuming a gallon or half gallon of water every day, and then suddenly when you check the levels the next day, they did not drink any water at all. This is NUTRITIONAL LOCKOUT.
Instead of giving lengthy descriptions of indications of overfeeding, underfeeding, ph imbalance, environmental problems and Nutritional Lockout here, it is easier to just give the remedy. Here we will refer to this remedy as THE RECUPERATION AND RECOVERY REMEDY.
THE 8 STEP RECUPERATION AND RECOVERY REMEDY
1. Check the roots. If they are discolored, reddish or brown, or present an unpleasant odor, you have a problem. If they are weak, soft or mushy, you have a problem. Also while checking the roots, observe the temperature of the water. If it is warmer than "luke warm" you have a problem. This problem is probably what is referred to as "root rot" or a disease known as PYTHIUM. Remove the dead brown roots by trimming them away with sharp scissors. Do not leave them in the tank.
2. Check the humidity and temperature of the grow area below the lights in the "growing zone" when the lights are on. A temperature of above 82 degrees or below 67 degrees will slow growth, but it is not a serious problem that will kill your plants. Temperatures below 62 degrees or above 90 degrees will stop growth. An extremely high temperature in the upper 90s or below 58 degrees can slowly result in death of your plants. The most efficient temps for growth are between 72 to 80 degrees. Any Humidity between 40 and 60 percent is acceptable and desirable.
3. Check the "lights off, nighttime" temperature. Most desirable is ten to 15 degrees cooler than the daytime "lights on" temperature, averaging 66 to 70 degrees.
4. Check the distance between the tips of the plant and the tip of the light bulb. If you observe yellowing or leaf curling tips, then move the lights one inch further away. A good rule of thumb if you use HID lights, is hold the soft palm of your hand at the leaf tip and see if the bulb is too warm to your hand. If you use Stealth Hydro's compact fluorescent bulbs, we recommend a distance of three or four inches for the 65 and 85 watt bulbs and 4 inches to five inches for the 105 watt bulbs. More mature plants can handle the bulbs slightly closer.
5. Check the position of your fans. Air movement is very necessary for the health of your plants, but too strong of a fan can cause wind burn. Direct your fan toward the tops of the plants and toward the lights. Never position the fan blowing strongly downward on the leaves.
6. Add 1/4 teaspoon of hydrogen peroxide to a quart of water and add it to the tank of six gallons already in the tank. Wait ten minutes and then turn the water and nutrition solution pump off to prepare to drain the tank. Poor at least a cup of clean water through each grow cup, onto each rockwool cube and through the hydroton rocks.
7. Drain or pump the tank empty as possible without damaging the pump by running it dry. Add two gallons of additional clean water with 1/4 teaspoon of hydrogen peroxide again and then drain it away too. Again, empty the tank as empty as possible without burning up your pump.
8. Add fresh PH balanced water and nutritional packets as prescribed. PH test it again.
The above 8 steps should repair and remedy any health problems that your plants experienced within the next two days. Now is the time to try and determine what caused the problem to start with, by investigating and researching typical hydroponics problems and illnesses. Here are a few DIAGNOSIS TIPS.
Typical Hydroponics Problems and Illnesses
Underfeeding and Weak Nutrition
The entire plant, both upper and lower leaves, will show lime or light green in color.
The plant will not eat, drink or show growth.
It is time to follow the 8 Step Remedy.
Overfeeding, Use of Too Strong Nutrients
The leaves will curl downward. They grow very dark dull flat green and then the tips show signs of burn.
It is time to follow the 8 Step Remedy.
Nutritional Lockout
You know that you have made recent PH adjustments. You might know you may have used too much of the PH Adjustment Solution. You may have failed to test the PH often enough. You notice the plants did not eat or drink because they did not consume the same amount of water they used yesterday. You see rust spots. The large lower leaves are prematurely dying and you are not in the BLOOMING or FLOWERING stage.
It is time to follow the 8 Step Remedy.
Wind Burn
You had the fan blowing downward toward the upper side of the leaves, instead of blowing up through the node spaces or toward the lights. You observe the leaves becoming dry or even crispy, perhaps shriveling, and the tips curling upward. The leaves do not appear glossy, moist and vibrant.
It is time to follow the 8 Step Remedy.
Water, Nutrition Solution or Roots Are Discolored Brown Or Have an Unpleasant Odor
You notice your water is becoming brownish in color, or smells distasteful. Your solution does not smell pleasant and appetizing like fresh lettuce. Your roots are not the same shade of white that they once were a week ago.
It is time to follow the 8 Step Remedy.

Looks over-watered, but there could be a few causes. I've grown a big plant with a 20 gph air pump in a 5 gallon bucket, and I always thought I was running a little low on O2.... very healthy plant though, so if you're not hitting it with at least that much O2 in the water, you'd wanna upgrade that department soon or perhaps just lower the water level.
Doesn't look to bad though man.... I'll bet it's atmosphere-related. Could be as simple as raising temps a few degrees, but you'll have to give us all the details..... every minor spec..... temps max/min for water and air, RH, EC, gph, on/off light schedule...... all of it... then we'll help you proper.

wait, so Roseman I cant use cat urine for ferts? what about enema juice? I heard this is very high in NPK.

what im doing exactly is i got a 1gal bucket with a 5 gal air pump connected to 1 air stone its on a time set for 18/6 off at 12 on at 6 im using "genral hydroponics" nutrients i have 4 100watt cfl 6500k when the lights are off i spray carbonated water on it and the temp has never gone above 73 or below 69 humidity stays around 33 to 40% and the last thing i can think of is i change the water every week

You got it all wrong,,,you drink the cat urine first, eat some mollasses and then you use the enema juice for fertilizer. Works like a charm!
LOL, REP for you !!!

Air pump is supposed to run constantly, 24/7.

Bad idea bro. You never need to spray your plants, and if you're trying to supplement CO2 you do it when the lights are on, cuz if you do it at night you'll suffocate them and they end up looking like that. Of course if you spray them during the day you risk burning them.

4. Check the distance between the tips of the plant and the tip of the light bulb. If you observe yellowing or leaf curling tips, then move the lights one inch further away. A good rule of thumb if you use HID lights, is hold the soft palm of your hand at the leaf tip and see if the bulb is too warm to your hand. If you use Stealth Hydro's compact fluorescent bulbs, we recommend a distance of three or four inches for the 65 and 85 watt bulbs and 4 inches to five inches for the 105 watt bulbs. More mature plants can handle the bulbs slightly closer.
5. Check the position of your fans. Air movement is very necessary for the health of your plants, but too strong of a fan can cause wind burn. Direct your fan toward the tops of the plants and toward the lights. Never position the fan blowing strongly downward on the leaves.
6. Add 1/4 teaspoon of 3% hydrogen peroxide to a gallon of water and add it to the tank per 5 gallons already in the tank. Wait ten minutes and then turn the water and nutrition solution pump off to prepare to drain the tank. Poor at least a cup of clean water through each grow cup, onto each rockwool cube and through the hydroton rocks.
7. Drain or pump the tank empty as possible without damaging the pump by running it dry. Add two gallons of additional clean water with 4 teaspoons of hydrogen peroxide again and then drain it away too. Again, empty the tank as empty as possible without burning up your pump.
8. Add fresh PH balanced water and nutritional packets as prescribed. PH test it again.
The above 8 steps should repair and remedy any health problems that your plants experienced within the next two days. Now is the time to try and determine what caused the problem to start with, by investigating and researching typical hydroponics problems and illnesses. Here are a few DIAGNOSIS TIPS.
Typical Hydroponics Problems and Illnesses
Underfeeding and Weak Nutrition
The entire plant, both upper and lower leaves, will show lime or light green in color.
The plant will not eat, drink or show growth.
It is time to follow the 8 Step Remedy.
Overfeeding, Use of Too Strong Nutrients
The leaves will curl downward. They grow very dark dull flat green and then the tips show signs of burn.
It is time to follow the 8 Step Remedy.
Nutritional Lockout
You know that you have made recent PH adjustments. You might know you may have used too much of the PH Adjustment Solution. You may have failed to test the PH often enough. You notice the plants did not eat or drink because they did not consume the same amount of water they used yesterday. You see rust spots. The large lower leaves are prematurely dying and you are not in the BLOOMING or FLOWERING stage.
It is time to follow the 8 Step Remedy.
Wind Burn
You had the fan blowing downward toward the upper side of the leaves, instead of blowing up through the node spaces or toward the lights. You observe the leaves becoming dry or even crispy, perhaps shriveling, and the tips curling upward. The leaves do not appear glossy, moist and vibrant.
It is time to follow the 8 Step Remedy.
Water, Nutrition Solution or Roots Are Discolored Brown Or Have an Unpleasant Odor
You notice your water is becoming brownish in color, or smells distasteful. Your solution does not smell pleasant and appetizing like fresh lettuce. Your roots are not the same shade of white that they once were a week ago.
