odd question

My ladies seem to be great until they get to about the 15 hour mark and then they start to droop down is this something that anyone else has seen? I have checked my roots for root rot but since I am new I was looking for brown roots or rotten egg smell which I didnt smell or see either. I thinkI am just being paranoid but I rather nip something quick before it gets out of hand and advise is apprecited.

Soil, or hydro? What medium?

This is the way the girls look before drooping.

by the way it looks to me from yer pics is that , you are over feeding them? (thats why the smaller ones are burnt) whats your temps like? whats the PH? do you have a fan on them ? looks like its too hot, just my opinion mind. Remember plants sleep , maybe yer fussing over nothing

some of those burn marks are from some dont bug me spray that my hydro store said would be ok with them since I spotted a couple white flys. my ppms for the little one is 200 is that still too much? my temps are a constant 77 degrees I didnt plan out the closet too well. as for fans I have a box fan blowing in cool air as well as a small fan to exhaust air. Every opinion counts in my book I just dont want them to die if possible.
