Hey Vet!
I can't really open the pics since I'm in the office now (you know, better be careful), but from the thumbnails, they look very bushy! My older auto is quite crowded too, but I never considered taking off any leaves yet. I'm worried about her not maximizing the potential she has, if I take away "areas" where she could collect photons.
However, what I tried to do (and it mostly worked for me so far), is I pulled the bigger fan leaves under the newer, smaller leaves. Well, I guess one needs some imagination to see where the leaves can go, it's just a tip that may help you. I have to notice that I could only do it with leaves that have a pretty long separate stem, but now they are below the smaller ones, and I believe it's better this way.
Keep on growing!
