My GDP did the same thing, hermie, bad, poppin pollen sacks just below week 2-3 buds,.... got 6 seeds off of a blueberry that got pollenated by the hermie GDP,..... week 2-3 of flower,.... SACKS!!! FUCK!

It would have been such a nice cross, and the pheno was a blend of GrandDaddyPurple, (coloration of the leaves being dark green with blue hues to purple if I got temps down) and the mild manners of the Blueberry, (And quick to bud, not a lot of stretch)

Sucks, but the 2 I tried are both dead now,.... I might try another outdoors, since the GDP was stable outside.
