I see what the Gardener from Middle Earth sees ... but it is not a male flower. If your plant was fertilised this shape would become the sheath over a seed. I think your plant is close to finishing ...
preferably there should be no signs of intersex but
personally i dont have a problem with strains that shoot nanners last weeks, most of the time they aren't even producing seeds.
i hate the hermies that produce sacks in early flowering.
