coco Grow help

Ok i recently put 1000 hps in 4x4 or smaller really dont have any ventalation yet, anaways the leaves are starting to turn white on a few spots could it be from over feeding? or just to hot the temp is getting like 105 at sometimes?

105!!!!!!! wow man u need to get some ventilation fast

Ya really no where to pull the air from kinda over my head with the 1000 wtt I think

Just my 2 cents, but 1000 watts for that size space is a lot. Without an exhaust fan and some sort of fresh intake you're looking at problems. Optimum growing temp is 79F, but I've had it into the high 80's and been fine. 105 is waaay to high. Good Luck!
