I wouldn't worry about it, even if they did release pollen, there would be no time for seeds to even start growing to any noticeable size before harvest.
They look pretty close to harvest anyway, so just follow your normal routine and ignore any stamens/bananas.
Harvesting too late will have a more detrimental effect on THC quality, rather than any effect a few late male stamens could ever possibly do.
Hope this helps,........ Organoman.,
