How long did you veg? A shorter veg time will probably lengthen time before showing sex in flowering......Also genetics play a big role as breeders isolate different qualities in different strains, if you know what strain you have you can get a lot of info off the net. But generally 1-2 weeks is accurate.

Good luck!!
