Hey kosherboy, please don't take what I say as "expert advise" cause I'm a first-time grower myself...
Currently, I have 6 females and they are about 5 weeks into flowering. At 3 weeks of flower, all my ladies were looking nice except one of them was starting to show MALE PARTS. BUT, it was only on the main stalk and on lower branches (about 4 separate spots). I sterilized a razor and very carefully cut off those sacs; they were still very small at the time. It's been about 3 weeks since and to this day, I have yet to see any more sacs growing on that plant. I don't know if I got lucky or perhaps later down the road it will show more MALE PARTS. Either way, I keep a close eye on it everyday and inspect it carefully...
Since this is your only plant, keep it and continue to remove any MALE PARTS. Maybe it'll do what mine did. From research I've done, it seems once the female cannabis flower is pollinated, it stops producing THC and uses it's energy to produce seed... Just keep an eye on it and keep us updated!
