I flipped to 12/12 8 days ago, i'm not seeing sex yet, I flipped early (3 weeks of veg), how long does it normally take to show?
should see signs of sex 7-14 days after flipping. ensure room is light tight for dark period, and be patient. the longer it takes, the more likely the will be female
I saw sex in 12 days males show sex first. http://forum.grasscity.com/outdoor-grow-journals/1330858-we-want-fire.html
