Hey
@dutdut .
Nice grow.
I disagree with some of what other people have shared.
The unfortunate thing about bag seed is that the mother plant has more than likely passed on the genetic mutation to her seeds through epigenetics. That's not to say the plant will be a hermaphrodite, the probability is just high that the seeds carry the mutation as a dominant characteristic; or the gene may simply be triggered through even a minimal stress to the plant.
Another thing to take into consideration is that the mother plant was more than likely a feminized seed to begin with; so you'll have the same scenario with those epigenetics.
SO, it's not 50/50 on being male or female; not at all. It's going to come down to environmental factors, stress, and dominant genetics; what ever they may be.
An alternative scenario, which is highly unlikely these days, is you have a good old fashion cannabis seed propagated the natural way.
Hope this helps, Good luck with the rest of the grow!
