I was on par with you up until day 7 or so. As of now, mine are like yours in height , but have no side branching at all. I've been 12/12 from the get go because I have a couple other photos in the same box that have been trying to flower for the last two weeks. 20/4 is much better, I just don't have any other route to go with the lack of space I'm working with here. I hope I don't suffer on the yield too much.
Looking great man.
