That's the first strain of his I grew + every female was great.
If you've already eliminated other possibilities (plant sitting near light leak/etc.), then it's just that specific plant.
Every plant is slightly different + hermi. plants are part of nature. There is no guarantee's of pure gender in plants/beans.
I've always just culled Hermi. females + toss their clones. It's no huge deal if you chop them b4 they spread pollen.
Personally never had a herm. from Bodhi, just pure females+males. Never say Never...
Hermi are always a possibility + I've had a few from TGA/RP/DNA/Sincity, but also stable pure females in the same packs (no breeder is immune to hermi.)
