I looked back thru the post but couldn't find anything about the strain, or what nutes you use...
Is it a 'purple' strain, or is it a bit of phosphorous defeciency? (purple leaf stems)
I guess the other's here have much better eyes than I. Since I can't see most of the action in these sucky photos, someone else will have to help. It's not the angle, as that looks ok. It's the lack of light.
