Nothing wrong with a few seeds. If your buds are loaded with them though, then something went wrong in the grow, but a few here and there, nothing wrong with that at all.

A lot of seeded buds are outdoor grown, and their appearance can fool your eye. Seeds happen when the males aren't taken out of the area the females are in, or the females got pollinated before they could take out the males. It usually happens in larger outdoor grow operations, as when you have a junbgle of plants, it can be hard to keep an eye on all of them.

I mean, I have had outdoor seeded buds that were amazing! Outdoor stuff looks not so great, but it really surprises you.

The odd seed even grows when there is a 100% free male area. It's just natural for that to happen sometimes. No big deal really, but like I said, if your buds are loaded with seeds, you're paying for seed weight, not flower weight, but save a few of those seeds, grow them out, get mother plant growing, clone, and grow LBs of the stuff.
