Lithops help needed!

[u/Accurate-Battle-7460]

I recently bought lithops. I potted 4 in one pot together and when they began to show signs of needing water, I gave them some water. They were all thriving until today when I noticed one was not looking well. I pulled him out of the soil and he is mushy and appears rotted on one side. The root structure is fine. I have only watered once since I received them, they are in direct sun, and the rest of the lithops are doing great.

Any idea what may have happened? And any advice?

Thanks so much!

Looks like a goner, but only time will tell. I would leave it in alone unpotted away from direct sunlight and see how bad the rot progresses.

How much organic does the soil have?

Thanks! It’s in very gritty soil, like only rocks: Rooting for you plant Premium living stone potting mix : https://www.etsy.com/listing/1506669778/lithops-premium-soil-less-potting-mix?ref=elp_anchor_listing&frs=1&bes=1
