Day 70-75 Night 60-65 I think it's just the smallest plant ..How warm is it in your grow space? Looks like it could be stressed.
check your temps and Rh%
good luck
It's a 1000 watter in a 4x4 tentShe wants more light, what ya running?
Plants stretch for light (stem/shoot/trunk growth). Flat leaves (parallel) are optimal for receiving light. “Reaching” upward is receiving less light. She appears “cramped” in the middle. Claustrophobia. Gas exchange/transporation issue.She wants more light, what ya running?
This is pretty much spot on, though I disagree with gas exchange being the main issue. I'd say its more likely the leaves are folding up to reduce light exposure and transpiration due to temp/rh/light stress.Plants stretch for light (stem/shoot/trunk growth).

Second look says that all are stressed, heavily. Nitrogen toxicity, heat issues, etc.
