Any ideas

[Keith]

I was tending to my plants and noticed on a few of them these sacs at some of the branches at the bottom of the plants. The plants look very healthy and grow real fast but I’ve never seen these before and was wondering what they are

I hope they are not genital warts! I have never seen structures like that before. No idea. Scrape them off. Might have something to do with bugs.

I’m not seeing anything, I only see thick joints or “beefy arms”

Nubs. They only add extra material at the fracture line (points that endure most weight), so will be like extra support for the branches.

maybe a good workout and diet made muscles there
if it grows fast and healthy then there is nothing to worry about.don't disturb

Thanks nice to have good issues

If you magnify it there’s like a black structure with like whitish fiber analgous, well i better not say that. Whatever it is i don’t think it’s part of the plant.

I think they’re dead stipules

the coloration seems wrong

Nothing to worry about_ you're good. Those "nodules' form when the branches are stressed from pulling on them_ kinda like stress fractures. But don't worry, like bones when they heal they are now stronger than before.
I get them all the time from aggressive LST. They seem to form most often when the ties are placed on the branches too close to the plants trunk_this seem to put more pressure on them than if you first set the ties further out on the branches. You can get similar growths when you super crop a branch, but where the branch was squeezed and bent over not where the branch grows out from the trunk. Happy growing!
