Mystery Berries (Virgin Grow)

Funny. It's been about 3 days since I last looked. And the leaves have turned purple on about 1/3. Large leaves and small one around and I the buds. Itooks well still so assuming some genetics of the mystery strain? Any comments welcome here as its my first grow. Took a sample of bud leaf and magnified it x 400. Possible slight browning at the ends. Not enough to call it. I'll look at the end of the week and make a call. Maybe time to flush? Update at the end of the week I've made a call to flush. Will ride out next week with no feed looking at a window to chop. Buds are swelling up beautifully. Branches are sagging! Been a joy so far on this first attempt.
