This looks like light stress to me? Its an ac infinity evo6 set to 30% at around 3ft from the canopy. Thats only 150w. Temps have been cold, 70 average during lights on 68 lights off. Im using a spacer heater to help but its not quite enough, and the light isnt warm at only 30%.

The curling only seems to be at the canopy and it is affecting new growth as well. Worse in the middle of the tent. Wth is going on here?

Plants are bioall365 and fed organic dry ammendments once per month and given ph 6-6.5 tap water.
