ehh yeah man.. hate to break it to ya but ehhh that's no "swollen calyx" or resign gland.. both of which are kinda similar.
that's a male pollen sack. Banana!!! (pollen sack)...
and yeah, if you picked off the pollen sack(s) while having other female plants in the same room.. your screwed brother. If you did that, in the same room with other female plants, you.. just pollinated all of your females bro. Dang..
You should always take any suspected male plants.. outside (the few males I've had, I always take them into my garage.. and then manicure them and use its stems and leafs for making hash with. Works great too.) doesn't matter where you take the suspected male plant(s), just make sure you take them to another room of the house.. or like I said, outside in the backyard or something.
I've learned to leave my plants alone.. undisturbed at all times. Unless they need attention.. but other than your normal watering every 3 or 4 days.. and a feeding of food once every other week.. I leave my ladies alone. I make sure that, the grow area, when "lights off times" are engaged, I make sure that its as dark as possible with no or very very minimal light leaks. I like to have zero leaks myself.. makes me feel better about things.
but anyhow, hope you didn't accidently pollinate your other ladies bro! Either way, good luck.. and even better luck next go around.
peace everyone..
