What's wrong with my obesa?
Recently started to notice these red spots on my obesa cluster. They are not soft and it hasn't been watered in 2 weeks. It's potted in cactus soil and lots of perlite. I've had this obesa since 2020..it was a single ball at that time, but then a rat came sometime between 2020-2021 and ate up a lot of my succulents including this one. The rat practically sawed off its entire head. I thought it was a goner but I kept it dry for months and then started watering it again and it pushed out a bunch of pups in 2022. It's been growing nicely since then. The pups are about the size of a pingpong ball now. I live in southern California. It's kept outdoors in an open patio. Receives full morning sun and is shaded by an umbrella in the afternoons. Could it be fungal? Or possibly heat stress? Or something else.. we have been getting some fluctuating weather recently, so could It be that? No pests that I can see. Anyone else seen something like this?
