my plants did the same thing. about 8 weeks in, with good flowers formed, all 4 produced about a half dozen seeds each.
if you're like me, you removed the males as soon as they showed balls instead of flowers. there's no way they could be polinated by those immature males! which mean, to me, all my plants were hermies.
it's possible, i suppose, that when i took a 5 day trip, and my friend had to water the plants for me durring the dark period, that they were stressed to TURN hermie. but these were bag seeds of reggie, mex dirt. so, more then likely they were genetically hermies.
herms are supposed to be less potent because of energy put into the seeds. but in my case, if their mothers had seeds to begin with, THEY must have been hermie. so, the smoke can't be too different. which means...shitty mex dirt weed. oh well, it's still grow experience. i wouldn't trade the knowledge. and i wouldn't destroy your plants. it's valuble experience.
