my plants have started to bud as well and look about the same as some of the pictures. Why are you worried about sex of the plants wtf wouldnt you use clones then there is no headache people come on now rookies lol
Looking good at about week 5 of flowering. Flowers getting bigger and pistils starting to orange at the tips, although one of my plants is/was stretching so it seems a bit behind the other two but whatever at this point.
