Is he a goner? :(
New lithops owner here...
One of my lithops has been tiny and wrinkly for weeks. He's not in his splitting stage so I tried watering him lightly, but it wasn't working. He did have a little scarring around his base, due to previous handling not by me, but it didn't seem to be anything major.
Several days ago, after reading up a bunch of things and watching many many videos, I separated him from the others (they're doing fine) to pay some extra attention to him. Trimmed the root carefully (most of it was dry and dead, but it still had a healthy-looking white core near the base), repotted in 100% inorganic mix in a small pot with good drainage, bottom watered to encourage root growth. He got slightly firmer, but otherwise didn't show much change. Today I took him out to check, and discovered that while he was starting to grow fine new roots, his whole base had white marks and some spots looked fuzzy, almost like mold. And shortly after these pics, the root broke off at the base.
Is there a way to save him? 😢 If anything, the body of the plant is still firm and not squishy, but he's definitely not doing well. Any advice would be appreciated.
