Where you're seeing that cluster is where my stardawg ix also likes to kick out a symetrical pair of calyx each having the banans.
Same plant when stressed will throw balls from the flowers higher up.
No stress = some stray bananas, eh no worries. The same plant on the initial seed run threw no male flowers, so I do believe there is some stress triggers happening.
IME with this stardawg the banans don't like to open on their own and aren't really pollinating anything.
Your flowers look very nice
@Slimjimham I'd give that one another run or two if the smoke is great, those bananas wouldn't bother me unless they get out of control or seed the whole room.
