The buds look a little different but I see nothing to suggest male flowers.
Under some conditions pistils will brown early and new flower growth will stop.
In these situations, I'm convinced something has flipped the "ripen seeds" switch. A number of my plants did this at various stages this year.
The calyxes swell at an amazing rate, and they are where trichomes are densest.
I'll be interested in seeing a smoke report.
Yours could be killer.
