I do not think you have an issue, what you have are leaves that are just now getting light LoL!Thats a lot of work right there! My goal was to try and get a grow where it’s very simple, plain RO water, and some LST/defoliation and that is it. I topped two on the right, the breeder says he doesn’t top these and they will stack up tight like a christmas tree. I may leave the left side alone, I’m not sure how that will workout. Last night I thinned them out a lot, then sprayed them with Fermented peach. This morning they looked happy but there’s some/an issue I see.
Look at the 1st of the 3 pics you just posted. The leaf with the curled finger is not a problem, it is what a leaf looks like when it has no room spread and grow and is in the shade. Look at the leaf set above that see how it has the same "bend" from growing into something else?
Looking at that same picture you really see the signs of light stress, notice the textured look of the leaves at the top of the picture. They should be smooth and not bulging. See how smooth looking the leaf with the bend you thought was a problem is? That smooth texture is how all your leaves should look. Not the bend but the texture.
Also notice the picture @Loudtreefarms posted, you can not even see his light fixture in the picture. Probably a good 3 1/2 to 4 feet away from the plants if not more.
