Are they still stretching? Not so much, I'm afraid. But the flowers are fattin' up, so I can't complain. I think I will end up with a 20 g of dry buds for each one (may be less, as a matter of fact), but it's still to early to say. We're in the third week of flowering, there is still plenty of time to build up the colas. Older fan leaves started to yellowing, I've defoliated a little to improve the airflow in the lowest part of the bushes. They still drink a little more than half a liter each, every other day, and I feed them with low doses of nutes twice a week on average. Long way to go yet...
