To quote:

"[the plant] should flower and display its sex — however the plant must be mature enough to present its sex. An immature plant will not show sex because initial calyx development is not photoperiod-related. Plants normally mature around the forth week of vegetative growth because sex is not genetically determined until the third week of growth"

How long did you veg. this plant?

Well ur flowering u switched ur timer to 12/12 right ? And if u are i think it might be ur strain cause some take longer than the others.
