I do believe you have a male, however, it is hard to see your plant under your lights like that...do you see any female hairs at all? ...or are you seeing any pollen sacks?
i dont see any female hairs every node has like a lil sack on it some have 2 or 3..i vote male and hes coming out of the closet..hahahahaha.....not bad for a first timer 4 plants 1 male! bagseed
considering if you are on a 12/12 scedule, with flowers that big, if it were female there would already be hairs stickin out of it by now. quick question, was there any branching at all before you put on 12/12. males usually do not branch intil they are really big. usually females start branching early.
