Noticed this just the other day while taking photos of the buds. Looks like a male pod.
I had an intersex plant my last grow, and it was only on a couple bottom branches. They sacs did open before I caught it. I only found 6 seeds in about 25 ounces. They were all found surrounding where the sacs were. Now, I’m not a long time grower, but I expected my crop to be seeded, not even close.If that's the only pod, I'd just pull it off and keep a close eye for any more, and remove as necessary. You might get a few seeds, but that won't ruin your crop. Can't tell if you're growing indoors or outdoors. If you start getting a lot of male parts, then I'd cull it.
