seeded bud...last grow

Hi guys... i realise that i must have had a hermie to have got seeded bud... but i never spotted one... is there a specific place on the plants that a Hermie can be seen or is it just random... ive read nannas can appear on buds.. but its the Balls im more referring too...any advice would be nice... thanks

I'm certain the bud grows out the balls to if it's Hermie. Could be wrong though but certain it does

They will grow yellow banana sacks on the buds. How mature are the seeds?
I'm betting it was a nanner plant. A true hermie is unmistakable
Edit: I had a plant this past grow that, it's first preflower was a male sack and ended up being female the rest of the grow. Could be something similar in your case

The seeds were dark and about the usual size for ( DINAFEM GORILLA ) all my environment is spot on with no light leaks.. im wondering if it was genetics...1 grew 9 plants last time and i would say about 3 were affected.
