Ok so here is the story. This is my first time making a real attempt at growing some decent bud. I have done a lot of research and read a couple cultivation books but something is happening I think it might be heat stress but I wanted to ask some better qualified individuals. My set up is as follows. I have 24 CFL warm spectrum lights at 23 watts each for a total of 552 watts in a 2' wide 4' long 3'8" tall box with one 100 cfm whisper intake and one out take fan. The entire box was painted flat white along with the cardboard reflectors. The plant strain is automatic ak-47 in 5 liter pots filled with a ph balanced 5.5-6.5 soil with added vermiculite for better drainage. The soil had said no fertilizers needed for the first 2-3 weeks. The temperature was way to high the first few days of there life pushing 100 F but I have since purchased a wall ac and have gotten the temperature down to 80 - 85 F And will be getting more fans to hopefully bring down the temperature along with using dry ice instead of the fermenting method to try to lower the temp further. The humidity is around 20 to 30 %. I water them with purified water balanced out to 6.1 -6.5. I have added a little jacks classic fertilizer at 1/8th strength at one of there waterings to see if that would help but I don't want to harm them. The plants are between 6 - 10 days out of the ground. And only about half of the plants seem to be suffering the others are deep green and doing great! Any help would be greatly appreciated if more information is needed please let me know.
Emergency!

Hey man, I think you certainly had a bit too much heat going there. It's good you got the temps back down, but try to keep em around 78.
I think you have too many lights for your current stage of growth. You shouldn't need that many lights until your plants get a little bit bigger.
Also, your plants are too young yet for any nutes, even at 1/8 strength. Give them a couple more weeks before you give them any. Hope that helps; good luck man.

yeah, Right now you want to get the environment perfect. Major cause of death at this stage is new growers doing to much.
When they reach 3 weeks begin nutes. Till than just get the temps inline and let them enjoy themselves.
Good Luck

u got something going here. these plants should look a deeper green and i can see the purpling starting on the leaf margins-these symptoms signify a nitrogen deficiency. being so young and considering already ferts in the soil, you should check the runoff ph and make sure N isnt getting locked out. also too cold of water and overwatering will lead to N uptake. could possibly be also considering they are very big for 6 days out of the ground, that they are fast growers and need nutes earlier in life. If it were me, I would check my ph and feed maybe one or two of them as tests to see which is the correct solution
