What is going on with this stem? A pathagon or fungus...or neither

Alcohol should kill any bacteria or fungus, most likely viruses as well. For my plant it seems like the alcohol dried up the center part, but the outer edges of the infection still get dark after 4-5 hours. I spray it twice a day.
Pillbugs or rolly pollys come up four feet to eat on the dark edges of the infection, something I’ve noticed they will do where fungus or bacteria is eating away on the stem. They will eat all other parts of a healthy plant as well though.
I don’t think the alcohol gets deep enough to work usually, or maybe the infection is into the cambium layer and becomes mobile in the plant

That is boytritis stem rot. Use alcohol then cover it in a salve. I use antibacterial ointment, neosporin. Keep a close eye on it or this will happen.
Grey mould is associated with rainy cold weather at harvest time, infecting and ruining buds. It's also the number one disease of hemp farmers, ruining the fiber part of the plant by infecting stems. All it takes is high temperatures around 20 degrees C, 70 degrees F. Above 75 degrees F and it dies. I get a marine layer that moves in from the ocean, burns off by noon. Otherwise sunny warm weather. Doesn't need rain to infect, in fact I think the rain washes off the mold spores and stops them from spreading.
That's all it takes. I saw the plant leaning but thought it was top heavy, didn't notice the stem damage. There was one windy rainy day and Snap! At least 3 branches were below the infection, didn't lose the entire plant!

That’s about what mine looks like revv, only it’s about golf ball size and not elongated. Luckily it’s a caged plant being supported, but it’s only got about 3/4 inch of green in that golf ball sized infection. Neosporin sounds useful, but it would prevent any more alcohol sprays, so have to be confident in that route before proceeding.
Does seem to be botrytis, usually is, mines in a greenhouse type situation so familiar with it popping up, usually very minor instances. As I understand it, it’s generally always present from overwintering spores, and high humidity and free moisture will start an outbreak. 58-80 degrees is optimal for outbreak, low wind helps outbreak as well. Dead tissue is usually a starting point, pistils being the most common I’ve seen.
My stem issue plant is a first in this spot in three years, but it’s closest to the evaporative cooler, about three feet away, coolest, most humid spot in room.
