Here's day 15 of flower for the B&S, the OG kush X Trainwreck isn't flowering nearly as fast, with the same treatment.
So far seeing very very uniform growth among the plants.. gonna be close to pick a mother... oh well, won't be for another harvest at least before I narrow it down to one.
Oh, and the first picture is the same bud from the second post.. 2 days later lol, crazy growth!
Oh, threw in Jorge Cervante's grow bible for size reference, useful book.. don't seem to need it much, but useful to have around!
