Do female buds make empty seed sacs or pistils

WW are also done swelling up and are also producing what I would describe as empty seed sacs but with two or more hairs coming out of them.They look like pistils in nodes and have hairs coming out of them and are opening up very slightly.

Is this part of the bud maturing?My sativas did the same thing.Right after swelling and trichs are very close now I’d call them pistils opening up in buds.
I though a herme but each sac has hairs coming out and is completely empty and very sticky.
They look like pistils in the nodes but are in the buds?
