Forgot to reply… it just appeared that way in this photo but im on a phone and my eyes are bad.
Cut open that lump and see if there is a larvae in there or if it was hollowed out.
Squish the stem see if its a bit softer in the ridge. Then cut vertically at the bulge and try to pry open to confirm.. if nothing the just let it heal and it will be fine. If there is a larvae pull it out and close it back up.Well that’s a bummer, I’ll replant the two healthier looking ones tomorrow and then see what we have going on…
If I find nothing is that essentially just topping it and the bottom will begin to fill out?
Very unlikelyOk let me run another possibility through y’all
First here’s the roots of the two infected or sad plants

I opted to transplant today and will separate them from everyone else
Was thinking, the door they’re on was treated Monday with ortho home defense (allowed to dry 24hrs), Tuesday after feeding on my driveway and allowed to rest till sunset they were moved to that door. Thursday I fed them on that door and didn’t elevate them to get out of run off, is it possible the roots at the bottom absorbed poison through the bottom?
Seperate them all if you think you could have bugs or soon each one will have the problem,sorry if someone mentioned it already
I think Aquaman gave good advice to get into the stalk and have a look to verify if you even have them. Get a mag glass and thoroughly look at the entire plant before doing it. Maybe a thin shallow slice with a razor blade won't do much damage and will heal quickly,you may not even have a borer.
Neem is like using dormant oil,it's decent but it won't keep mites,bugs away for long as it smothers rather than kills and prolongued use inhibits growth and insect stage depends on effectiveness . the best non systemic you can buy is end all and most plants love it and it's easily washed away whereas neem stays "in" the leaves and takes time for plants to recover. I use endall even if i don;t have bugs as a boost,it has pyrethrine and potassium in it and made from chrysanthemums and harmless to bees
if its a borer you will likely find clues to it's entry or anomolies in the stalk,i've seen it in corn and theres usually eggs and they seem to go where the leaf comes out and everything there goes black from necrosis,that spot you had circled where there is a lump and a track seems like a logical place to put a tiny cut if you have eliminated other reasons,again you may be off assuming it is a borer. Do the basics first and check it 100% for external bugs and make sure it's not grower errorI think his advice is great please don’t get me wrong with all this questioning, I just don’t even know where to start slicing Fan leaves are effected from bottom to top of both plants, there is that trail on the stalk which I suppose the top could be where borer began its entry? I could slice there then down but where dose one stop? If the fan leaves are effected at the bottom and the top idk if it’s going up or down? I was kinda hoping I would start to see a bulge then go after the bastard….
