Northern Lights Auto (First Grow)

This is my first time, but I believe we're in the middle of the "flowering stretch" as our main plant packs on the leaves. The white hairs are all over the place, I attached some close-ups of the bud sites. I don't think I'm going to use nutes on both of the plants, I am going to do it on the one I am NOT LST to see how she takes them.
