Strawberry Cough

So she has had decent growth in last week. All week though she started drooping with leaves feeling papery. Last few days some of the leaves are twisting. I moved lights up 4 inches(helped a little). Not sure if the switch from flourescent to led is the cause? Its been 9 days under leds. The leaves wont fully pick themselves up(like praying). I have 3 other plants(same strain)and 2 other plants(both different)in same room. All plants have shown this behavoir. Same soil mix as last grow with no issues. Soil at 6.7 ph. Also 2 of the strains were in the last grow with no issues.
