That plant won't show sec for another few weeks. Also get a fan on it if you do t have one already. That's the wind that strengthens the stems.
It definitely absolutely positively WILL SHOW way before a month into flower. Most plants will show in the twenty five days from sprout range.
My plant has been going for about 2 months and hasn't shown... hmm or maybe i see them and im still like maybe its male.. No one could answer my post.. Wait till you flip 12/12 and about a week or so.
