For a behind the window grow, she looks fine to me.
But you should aim for ph 5.8-6 in growing stage instead of 6.5
In my opinion 6.3-6.5 is for flowering.
Goodluck growing :)
I think you over trained her a bit but that's okay. I'm really struggling a bit with that type of thing myself. I usually dont do much pruning but today I went nuts lol and I went ahead and pulled it over on week 2.5 basically
