Showing some heat stress. (upturned leaves on growing tips)
I'd ditch the rest of the foil, as it is useless in a growroom, closet or box. (collects, traps and radiates heat) Shiny...yes. Useful...no. Flat-white paint works great though.

Might want to raise the lights a tad also. Got a circulating fan on 'em? (can use it to blow-away the heat from the lights)
Rusty Trichome Reviewed by Rusty Trichome on . Please comment on my first grow...Romulan Romulan, i think, started from seed. Four female plants stood out of about 10 sprouts. Pics about 2 weeks after forcing flowering. Different start times per seed, but they all seem to be catching up to eachother. Had spider mites appear, sprayed with water till i nearly killed plants, not intentionally, but killed off the spiders it seems. Had some flies biting at them, but after removing males i put the fan blowing gently on them and seems to help keep flies off. CFLs are 100 watt Rating: 5
