So I just got my new room built and am having an issue I've only had in small cases but now it's effecting a good portion of my garden, I'm pretty sure it's heat stress even though my room isn't getting above 80. I'm currently only running 4 600's at 2 feet, it's a 10x8 room, good air movement, air cooled lights etc. I have 3 strains which are sherbet, the white, and ghost OG. The OG is the strain experiencing the stress with taco leaves I've done everything from putting a humidifier in the room (cause my room is very dry) to light flushing them cause I did just feed them for the first time with canna terra and some additives so my only other guess is it's heat related. But it's confusing cause everything seems right. I should also mention though I did only notice it the same day after 1st feed but that day I also flipped another light on. So I'm just looking for some input and suggestions, it is still very early I got another month of veg so there still very young and can bounce back ive got pictures as well if you need. Please help
