DrJynx86answered grow question 4 years ago If you're on a 24 or 20 hours of light schedule, and they haven't started flowering, that might be a f-up on the seller side and that's a photoperiodic plant instead of an auto.
Switch to 12-12 for a week or so and see if pistils start coming out and she's a girl. And then you can confirm the f-up and just continue the grow as with any photoperiod plant.
