Ok now that they are getting hungry I now know that they have used up what food they had from seeds and rooting cubes(clonex dome).
0.5 EC or 420ppm(I normally do not use ppm reading, for my Bluelab meter reads in 500 incr. and not 700 you will get into trouble by over feeding everytime,I prefer EC reading as this is always exact giving your calibrated right"always calibrate instruments every 3 to 4 weeks")
I follow the Advanced Nutrients calculater for VEG with 2 part grow calculate for 4.9 gallons.I follow this until before cloning.After I clone from Mothers then I follow the there Mother feeding schedule with 2 part grow.
AND YES I do USE everything they recommend + Cal-Mag.(I hear all the time It COST SO MUCH MONEY.Here is how I look at it: One: They are the only company to say that there product is for Cannabis. Two: I have been VERY SUCCESSFUL with there INSTRUCTIONS I mean 2lbs + with one 1000w HPS in 4x4 Flood and drain so yes I will spend the extra $200 to increase my YIELD and my FLAVOR.(always flush last 7 to 10 days and I use unrefined sugar,fermented molasses or pure honey from local hive.the taste is unreal with one of these).
DO NOT GET CHEAP HERE.Your plants will love what it needs and not what it gets....
OK LOOK at it this way.Yes you can workout,Jog,hike whatever your fix for health now you can do this while eating McDonalds and get only so big,healthy and get just enough nutrients for you body to live,but in the end you will develop bad health years down the road,VS if you eat fresh Hormone,Antibiotic and pestiside free food that is full of the nutrients for your body to heal to fight disease,cancer and all the bad conditions our polluted world gives us.
Here is something for the MIND.(I love to drink Coke Cola and Dr Pepper)did you know it takes 32 Glasses of ( 9PH ) water to reverse the acidic effect of one can of coke.If you plants are so sinsetive to PH level.then you Body will be no different.Ok I know Im preaching now but if you use Coke cola to corrode calcium of battery cable (calcium it eats it) and the docs cannot understand why ARTHRITIS is on the rise,what do you need for your bones to grow strong CALCIUM...So take care of your Body(temple) as you do your plants and you will love the rewards.
MY TWO CENTS.
78f and 37% hum. this needs to be addressed now never above 75 f and atleast 50% to 60% hum. I must adjust issues in room to address this problem now NOT later.
Now they start to green back up(always nice)
My room is only 13' x 13' So all I need for humidity is a $40 humidifier from Walgreens.I like the ultra sonic over motorized units due to bacteria build up between the fins of motor and areas that are hard to clean this is not the case with the ultra sonic version very easy to clean also I have paid close attention to see if the Ultrasonic Freq would effect plants I have NOT notice a problem.
