Sativa, Indica and a hybrid after a quick search. Making them all unique.
I maybe wouldn't have, but you may have timed it right before the stretch...
Good stuff, right? Are you following their recommendations?
Did you top squirt? If it is untouched it could be the genetics or strain or something entirely different, I wonder too.
This is where I can't offer anything, I have tried to stay focused outdoors. I have read there are many lights with high numbers but they read differently from the outlet or something. If you did not research your lights before you bought them do some now, they may be the best..over my head here
The two bushier plants look like they are happily getting light to all their sites. If sprout was mine, I would reread the two IntheShed tutorials in my signature. I know that there is a warning about autoflowers and lst. I corrected most of my first half assed errors finding those tutorials, my jounal shows where I rerigged my crop with the main cola below other growth - turns out that is the point.
Read them, seriously, they're pic heavy and awesome!
