Nanners aren't an end-game. Those can be fixed. Man, that really is a dense hedge-looking plant. Will you need to do much leaf removal for better light penetration? I have a tendency to do as little of that as I can. I'll try to grab a pic of my lone BCP in flower right now...lmao. It still has ALL of it's clothes on. I'm sure I'll regret that in a couple more weeks when those buds start to swell.
You mentioned they were 10 weeks into flower and you took a tester branch...what did the trichomes look like?
