ok so the problem was that every day they start out fine then by the end of teh day like an hour before the lights supposed to shut off they are so droopy by that time.. ive changed the nutes and put a fresh batch of week 3 gh nutes in ( they were taking them all great from week1 and 2 so i know there not too strong).. ph has been adjusted to 5.8 the light was moved about 20" away from the tops.. got the fan really blowing around.. heat in the room adjusted to 79-80 degrees with heaters and nutes were placed on insulation and cardbord.. roots were also covered with mylar in strips with cardbord.. i picked up a few of them today to look at the roots they look good but there was a couple dead roots that i just pulled off . a lot of the roots have like a slimey brown coating on them but if i wipe it off it is very white and healthy looking but there are a few roots that just pull off like they are dead; im using fossill fuel humic acid which makes my nutes and stuff really brown so thats what im hoping it is not root rot. i didnt add the humic acid to this new nute batch only gh and superthrive and i fed them one time around 10 pm before the lights shut off at 12 and they were still drooping even after the feeding.. im goin to not feed them at all tommorow and then wait until the next day to feed them. they're like 5-7 inches tall and i feel like they havent grown in a few days since this new change.. i hope thats enoguh info for you guys to help me i know its long but plsss help!!.. i also have anti-wilt spray i was wonderin about that but im not gona spray it kuz its just for transplant shock and moisture it says.. but let me know what to do pls!!
