Need pics to determine, but in my experience self-pollination does not occur until flowers are almost fully formed. I found a seed today in one of my jars I've been smoking out of for 2 months. It surprised the hell out me, one seed from an 8 foot plant. Technically, it was a hermaphrodite...but I'm sure as hell not tossing all this good dope b/c I found a seed.
Smokes just fine.
