Hermie

Common urban legend: - Once a plant grows male flowers, it will only keep on doing so ... totally false a plant can grow few male preflower the first few flowering week and stop afterward - If you miss even ONE, you potentially ruin your entire grow ... false as well in most case you ll get 4 12 seeds wich doesn't ruin yuour harvest potency even with a small fan blowing top of canopy - your best shot is to get it out of your tent into another grow space immediately ... false in most hermie case you can keep the plant in the same growroom withoput risk and as organoman said a single male flower can release enough to create 100s seeds, but that doens't mean it will from my experience even with a small fan blowing top of canopy you'll will only get a few seeds, pollen don't spread that easily without strong wind or manipulation i once even had pollen dropped bottom of canopy on a stem and leaf that i didn't care to remove with moisten sponge/paper towel and only get 2 seeds in the end for 8 plants DoN'T SpReAd the hermie fear ...

You will have to remove the male flowers, - one mature, opened male flower can release enough pollen to create 100s of seeds.

pluck em. Maybe not grow this one out again. Growing nanners are normally from stress and a normal response depending on the plants tolerance, but growing full on pollen sacks or male parts, is a hermi trait. If it just a few ok. Long term not the best plant to be growing out. Good Luck!
