U jedné kytky se mi zdá že je něco špatně ne...

I don't really seen 'bananas', so it doesn't look like a hermaphrodite to me in that sense, but your pictures are slightly out of focus making it hard to resolve smaller structures on the flower. The leaves coming from the flower look unhealthy. Not really any way to see if there are 'balls' forming from these pics but you could look under some of the flowers. Sorry this isn't much help. No obvious signs of hermaphroditism though, maybe just some other issues?
