Honestly after looking closer I wouldn't say that is due to lights. Praying is when the entire fan leaf faces upward at like a 45 degree angle and tacoing/canoeing is when all of the edges curl in. That really just looks like the rH in your tent changed and your fan tips just bent like that because they are shrinking in on themselves. Ive seen that in the past when I had low rH. Even just for a little bit. Nothing I worry about.My Led light is set on 80% because of the Gorilla Cookie girl, I was afraid to burn her... if I have to lower the power even more, maybe I will have a lack of light, don't you think ?
The tips clawing up on some leaves is from this morning, the few past days the plant was praying... I wish I knew more in order to interpret correctly what the plant is saying.
Oh well, so much to learn !
As far as the lights go your plants look good right now so I'd leave them where they're at.
And yeah I know what you mean, every plant is different and it's always a learning process. Still learning everyday myself! Keeps it interesting.
