You are going to have pounds of weed bro. The extremes seem to more finicky then the think different I suffered some leaf damage on both my extremes while the think different on the same schedule suffered nothing at all. I think your auto ultimate grow will be nicer looking for you. I have a feeling extremes are finicky and need some extra heavy attention when it comes to deficiencies. I was reading in the latest high times about pruning large fan leaves they say even thought they are dark green and look pretty and healthy It is important to realize that at the halfway point it has reached it's photosynthetic peak. This means that photosynthesis gradually begins to decline in the leaf and creates less sugar for the plant's nourishment with each passing day. Eventually the leaf will consume more energy than it produces. So I do not think you will hurt but help your plant to prune some energy sucking leaves bro. Just a thought
