My plants need help..

My little ones are on day 26 of veg. Using Fox Farm Ocean Forest Medium, Fox Farm Trio Nutes (Fed once with 1/4 strength grow big & big bloom 4 days ago), 250 Watt HPS @ 16" away from the top of plants. I had some heat issues for about a week before today. Temps in my Box ranged from 95-100. I managed to get them down to 85 today.

I have 2 plants right now, the one is beautiful, no visual problems right now.

The other started bloching on different leaves, with yellow/brown colors, some leaves have holes in them. I saw signs of this while transfering them in to pots and putting them under the HPS. I thought it may have been stress from re-potting but it is starting to spread.

Does anyone have an idea what this problem could be?

Sorry for the crappy cell phone pics.

It could be a multitude of things. Those plants look way stressed out.
Don't Veg under HPS. Go to Lowes, and buy a couple of dome lights, Y splitters for 2 bulbs, 26W 5200K CFL's and a power strip. Veg under 5200 CFL's and you will get amazing results.
You temps are way too high. I suspect that is your main problem along with the wrong light spectum. The CFL's will take care of the heat problem. When you get to flowering make sure you can vent the room.
Blotchy leaves are sometimes attributed to lack of magnesium. Buy some Cal/Mag.
Good Luck.

Cool, thanks man.. I can switch the light up tomorrow. I did my last grow with all CFL's, so i have plenty of splitters and CFL's. I was thinking about switching to 12/12 on friday, but maybe i should just wait until they show their sex first. What do you think? Can i add the Cal-Mag with my nutes?

Humidity is down around 28-35%. I havent checked it since i got the temp. to drop down. Will check tomorrow afternoon. I watered them on Saturday, and today they were dry again. Im thinking it was the high temps in the box that dried them out so quickly.

Thanks for the help guys. Hopefully, i can get them healthy again.

cal/mag always nice to have, but it shouldnt be nessicary for a plant that small...85 with good air ventilation/movement should be fine...and you can veg just fine under a HPS, wouldnt make sense to switch out to CFL unlsess you just cant keep your temps under 90...

Ok, im going to buy some anyway, just to keep around. Yeah, ive read in numerous places that vegging with HPS was fine. I think im going to build a new grow box anyway so i can use my current one for vegging, maybe with some T5's. The one i have now is just too short, my light is almost to the top of my box (16" from top of plants to bulb) and my plants are still small. Thanks again man!!

Do you think it will be ok to trim off the leaves that have damage to them?

What are you talking about NOT vegging under HPS???? It is perfectly fine to veg under HPS and that's all I have ever used and not EVER had a problem... Don't waste your money going out and buying a different light cause HPS is FINE to use

ok there is your problem, I have been using growbig for YEARS. At this point I would start feeding them 1 tsp per gallon every watering. Growbig is great stuff your just underfeeding them. and to be honest don't waste your bigbloom in veg cycle cause you don't need it. In the pic i posted, those ladies were fed 1 teaspoon per gallon every watering, I know the bottle says 2-3 teaspoons every other watering but I found out that 1 teaspoon per gallon every watering works better but make sure you only have to water every 4-5 days. Also have you checked your ph of your water, perfect ph for gb is 6.5. Another way to green them up real quick is to foliar feed with 1\2 teaspoon per gallon and spray both sides of leaves.

ok great. One question for you. in order to water every 4-5 days, im going to need to water them pretty heavy right? right now i water until the water starts coming out of my holes under the pots. Doing it that way, my plants get thirsty after 1-2 days. So i basically should double the dose of water when i water them? or, am i giving them enough water, but my temps in the Cab are just too high and that dries them out faster? thanks for your help man, i really appreciate it. If i knew how to + rep you i would.. haha.

no prob man, what's your temps in you cab? Plus you wanna make sure your soil is nice and saturated with water, you might have to water slowly cause I know when my soil gets real dry my water seems to flow out the sides of the pot without actually penetrating all the soil so water slow, sounds weird but works. If you do have to water every 1-2 days then I would feed every other watering.

Well, My temps were up around 96 for about a week. I got them down to around 90 right now. My cab needs some improvements. Im using them booster fans and its not working out too great. Going to get a 180 cfm blower for my exhaust this week. Hopefully that will do the trick. I will water them real slow tonight and add some grow big to them.
