Are these seed pods or swollen calyx?

These thing got me scared because I squished on on another plant a few weeks back and it poofed like pollen. Only one I found but now a week or 2 away from harvest they are swelling over night and I jist can't tell.. they don't look like nanners and they have pistols coming out of them.. these plants have been through a lot from weather, outdoor tonindoor, heat and humidity fluctuations by about 20 degrees day/night, spider mites with they still have some (plane to bud wash to rid of dead and live before drying and curing) . Also hear putting the buds in the freezer for a couple hours will kill them instantly all though I don't like the thought of pest in my freezer. Lol

Outdoors pollen travels for miles.

Just pinch one off and examine it. You will be able to tell if a seed is growing in there. I'm guessing not a seed though.

Yeah as said above you can just pluck one off too check. I'm gonna say seeds, though - second pic a few of them look to be split open on one side...
