I flipped a photoperiod to bloom 16 days ago (13 hrs/day darkness after 8 weeks in veg), and still have no growth that is a tell for sex (it was a feminized seed buy, so _should_ be OK). This is part of my first grow AND my only photoperiod plant. The autos are doing well, probably 3 weeks from harvest, but this photo is causing me some concern. Should it take this long to identify sex, or _any_ kind of flowering growth?
