Heat Stress?

What do you think heat stress?

the leaves curl up when its to hot

can u get a pic of the full plant. is it only on lower leaves?

They are actually on the very top leaves.
Here are more pictures.

how far away is your light ^ what is the temp./ humidity at? & have u gave your plant any fertilizer?

Temp % Humidity cannot be determined ATM my digithermo took a dump but they were sitting about 2inches under a 2' 4 Bulb T5 HO. Also there currently sitting in a brandnew growbag with FFOF, so I've been giving them PH'd water only.

my best hypothesis woud be that the P.H. is off & maybe try a light feed of something w/ trace minerals.

So a light feed with trace minerals. Maybe PH'd water with Liquid Karma? w/NPK of .1 .1 .5

yup sounds good to me. let us know how it does in the next few days

have you sprayed them at all?

I had to use a azamax / soap / water spray solution on them but I let them completley dry before I put them under the lights.

cool, i like to raise my lights an extra 6 inches if possible for a day or 2 after spraying any oil based product. it can help to give you an extra safety net against burn. also medium stress can sometimes lend itself to that particular yellowing. i like to give em some straight water the day before to minimize stress. hop that helped
