You got nanners. Sometimes they're sterile so you have nothing to worry about, but in most cases, you have to kill the plant or try to remove them WITHOUT BREAKING THEM!
If they just popped up this week, you may be okay but if they've been around for a week or two, then strongly consider removing the plant. Looks like you're still a few weeks from harvest, so it's very risky to try and finish her.
Light stress will often cause nanners late in flower...
