I was away for a week and, boom! they have doubled in size.
They have started showing sex, especially the 3,5lt one.
I've decided to ease on the defoliation for now as they're developing good side colas and the "easy" training is responding well.
Do they suddenly explode in size after week 5 or so? They just don't seem very big. I am growing the same genetics, and mine are the same if not a little smaller.
