Lolgeneral photophobia?
Seems you are convinced it has something to do with the fertilizing but as the variable factor in the problem is lights on/off I don't understand why you are immediately dismissing the lights and their heat as the source of the problem.Thats not the issue, but thank you much any input is and will be much appreciated !!!
have you been using that the whole time?? that could be the problem... they are perking up expecting light and you are just giving them crap!!!just house bulb on now till i figure this out
Bro thank you so much...Do you happen to have a CO2 injection system that comes on when the lights do? It could be CO2 poisioning.
The plants that are drooping could be rootbound and the leaves droop to shield the plant from the light.
I'm just guessing though.
