Does the round thing inside the red circle on image 6 look like a pollen sac? Should i be worried? It has hairs growing out of it, which is not really a male trait or is it?
These is called a Bract. A bract is signs of its sex. It has a hair coming from it.
Its whats different
Cals build up to form bud after pre flower, like building blocks.
It is a female calyx, exactly like it should be.
You have nothing to be worried about.
On rare occasions you can get male flowers with pistils, but this is not one of those.
