....Doogal, that's your call mate, if you want to run the risk and micromanage her to harvest, or isolate her is possible, or ditch her,....
..I'm not following you on the stunted PEx being the culprit? She looks knocked up, but I see no male flowers on her,... likely the CB was the culprit for that, which mens some mature flowers have already releases pollen! Those other pics are showing the so called pre-flower bracts (aka calyxes); if you see "hairs", pistils, then it's female,.. male flowers also form stalks from which the flower hangs,....
So, you're faced with a room/tent-clean situation at some point,... lingering pollen can still knock up other girls!
