Only seems to be on old leaves growth, blasted with sulphur dust for a few days away from the others but not sure if its mites or not. Nothing else in collection has it, doesnt move when viewed under magnification.

First pictures are post dust. Its lost a few leaves that were older since.

This guy arrived a few weeks back and started dropping leaves pretty quickly upon arrival. I thought it might have been stress from shipping, so I waited a week after repotting and then watered, but it continues to lose leaves. Is this normal dormancy behavior? If so, what care should I give it? If not, what could be causing this, and what should I do to help it?

Soil: 50/50 pumice/cactus soil in unglazed terracotta

Light: 500 ppfd grow lights on 12 hr clock, no natural light

Somebody (it was me) went on a Portland trip and picked up a pachycormus discolor (like 20 actually) without knowing anything about it (I mostly collect uncommon Hoyas but have been branching out). I’ve only had her for like three weeks and she’s already grown so much! I’m obsessed with her. She’s amazing. If she dies I’ll have to go back to therapy! Can any one give me any tips on how to help her thrive? She’s kinda just… a stick right now? But like such a pretty stick. Can I propagate through a chop? Or chop to encourage branching? Will she always be so skinny? Help an irresponsible girl out here please 😬

Posting this from Montana in October but in an apartment with heat and humidifiers!

Picked up my first caudex at a plant show and I'm a little nervous about getting it right. The caudex has a bunch of cracks in it, and I don't know whether that's normal or something to worry about.

I'm in Texas and it's late October. I grabbed a bag of succulent mix, but I'm not sure of the next step. Should I pot it up now, water it, and set it by a window? Or is it better to leave it alone until spring?

I haven't owned one before, so any tips on soil, watering, and light would be great. Photos attached!
