Help! First grow in tent and is this a swollen calyx or seed pods??

i have 4 plants in a 1x2 1x2 tent and one off them I have been picking nana as off them for around a week I thought I could control it but then I found these this morning I can’t find no pollen anywhere open on the plant just these, plus i have another 3 lady’s in there that haven’t got any nanass on them I’ve checked them thurally, They are bang on 5 weeks in flower tomorrow since the 12/12 flip and I don’t know what to do with this plant or situation.

Here’s some pics I took just then.

You got a couple seeds. Not the end of the world. At this point might as well just keep what you're doing. You might find a few seeds in the other plants as well. They'll be feminized seeds.

Chopped it down at 5 weeks cut it up earlier on took me 2 hours i found 2-3 pollen sacks ready to open on closer inspection.
