Those aren't hermies. Most/All cannabis produces 1-2 "Calyxes" per branch site, usually located on each side of the side- branches base.
If these were hermies, you would be finding small yellow "bananas" protruding from the calyx sites where there are white pistols, both at branch and on fruit.
If a plant is pollinated, it's pistils will brown and shrivel into the calyx site, imseminating the reproductive organ and producing a seed inside the calyx; 3-4 weeks after pollination, of the plants are healthy the seeds will begin to rupture the calyx exterior.
