thanks dude, i ordered the 160 cfm fan on the 5th, it shipped today so it should be here around monday. The heat stress is actually not from temps, its from the fungucide spray I sprayed on them, I guess I underestimated the time it takes for the plant to dry off before the light comes on. So the top is a bit burnt, it looks like the vertical growth is nearing an end on the colas and soon I think their gunna fatten the hell up within the next 3 weeks. The yellowing has ceased a little bit also. I wanna put molasses in with the next feeding, does anyone know the amount per gallon? I'll take pics over the weekend, the battery on mine died and I can't find the charger. Cheers :rastasmoke:
