Lithop help.

[Cronkss]

I attached some photos. The nice looking ones I got a few days ago. The safe ones I’ve had for a few months. I live in Reno NV (USA). They are indoors under a light. Just got a pumice lava rock mix and will mix with organic. Was thing 80% pumice/lava rock and 20% organic. They have been in bonzi jack mix. I haven’t watered at all except a very very little (a couple drops two months ago when transplanted). Can’t tell if need water or are rotting. And don’t need any water. Should have new soil in a few days and plant to repot them all into the proper mix but any advice on what this is / what to do from here on out to help them and keep the others happy as they look now?

Thanks in advance new to the forum.

your Lithops are dessicated
more water is the solution

Definitely thirsty, although It isn't uncommon or harmful for Lithops to get wrinkly in winter. There are new leaves growing inside and you just need to keep the new ones happy. In England, getting rid of the old leaves is the hard part and we hardly ever water in winter, but things may be different in your climate. Lithops will go dormant in very high heat, and you may have enough winter sun that winter is your main growing season.

Roots aren't great on those Lithops though. Ideally you'd have at least half an inch of permanent root, which might not look like a lot but it is a base to sprout lots of fine roots when there is any water about. Plants with tiny root stubs have less ability to produce feeder roots.

Plant them, maybe water once and see how it goes from there. In general, Lithops should be watered generously and then left to dry thoroughly. They need a little time to produce a set of roots, then suck up all the water. Very light watering will not trigger the fine roots and the plant will just take up a very small amount of water, enough to keep it ticking over for a few more days.
