I don't see light damage. Looks more like the start of a deficiency. Possibly phosphorus. I know the purple buds I've grown definitely wanted more of it then my other plants.

Trainrails
In the middle of the picture from day 25 there is something weird going on with the new growth (next picture is more detailed). One side is growing really slow, the other looks like it never grew/was eten/something. It is kind of brown/red-ish. Is this a deficiency or windburn?

I could be wrong, but it looks like my leaves are starting to show signs of deficiency or am I just being paranoid?

To defoilate or not to defoilate.. that is the question!
I've always heard that you shouldn't "defoilate" auto flower cannabis, especially if they're a sativa to boot. With that being said, (looking at my pics for reference) should I do more defoliation? Would doing so really increase my yield significantly? Thanks
