Yep, sorry to say, but you have yourself a hermie. I've only had one, myself, and it had quite a few of those little balls on it, and I picked all them off and finished it out. Ended up being some really good smoke, and didn't find any seeds at all. Keep an eye out for little banana-looking things growing out of your buds, because they popped out all over mine towards the end of bloom. Pick them off too, and finish it out, just make sure to trash any clones from it, of you'll end up with more hermies. Also, look closer under all the buds, that's where most of those little balls(pollen sacs) form. Maybe you'll get lucky and only have that one, let's hope.
To me it looks like a seed
