What pest creates a ring around the branch like that? Seems like it cuts off any flow to the top of the branch and it slowly dies.

I have something similar in my yard that bores into flower stems.

The ball is filled with a sawdust like material - which I take to be shit, and there’s a small white maggot. Have no idea what it is, but guessing you could slice open the stem and check on cannabis without doing real damage.

But it could also just be where the stem was damaged. This is pretty common if the stem is super cropped and forms a nodule.

There’s also hemp borers.

Now I see what you mean. It reminds me of a canker, which is caused by a fungus. They usually spread from leaves or buds higher up on the plant. That may not be what it is, but I think I'd cut the stem below that point and get it out to the garbage before it spreads. I've read that fungi on the stem can be hard to eradicate.
