Take a couple of those off the plant and cut them open, if they contain seeds it's been polinated. Even if thats the case they will still produce good strong buds. The only thing effected will be the overall size of the flowers( this is because the plant will be focusing more energy on seed production instead of flower production) aside from having to pick a few seeds out before you smoke it, its quality should still be spot on. I am growing the same strain this year and 2 of my 4 plants have definitely been pollinated, and I can't figure out which one id the hermie.
