She is looking sweet I'd flip in a week just because they are gonna be so huge into the flowering cycle .. maby do some light defoliation and some hard LST as she begins to flower but ya they look very healthy how big do you want em lol ..
Looks like you have her trained really nice. If I was going to flower her in 2 weeks I would do a defoliation now to open up any budsites that are hiding in there. She has the potential to put off a big yield!
