I see these really small things developing on one of my plants, but really nothing to be sure of yet. It's been a little chilly lately.. hitting 80F in the growroom. Lowest my thermometer said was 76F i think. Of course, I have no idea if it's accurate.. Since I raised my lights higher and higher it's been showing lower temps, but I can't really find a place for it so it's at canopy level.
I think that in a week, week and a half I should see sure signs of sex. Maybe 2weeks for the second plant, it's not as far along.
