That lowest leaf looks waterlogged - I usually do not water plants that were just repotted. Many do, I wait for a day or so. How long, it depending if the roots were cut/damaged or wet from being in wet soil before. Hopefully, it is only old leaf that would have die off soon anyway - that would be best case scenario :)

Another thing to consider: you said you put it under lights. Did you acclimatized it?

I would also use more perlite or any other 'grainy' substrate in the mix than what is visible.

I was lucky enough to find a gallon pot of these at Home Depot a couple years ago. This plant I've noticed can handle a good amount of water. Last year California received tons of winter rains. I didn't really protect this guy all that much during that time, and he was one of the few plants that loved every second of those rains.

That leaf looks pretty normal. It's still attached and what looks like the plant is absorbing that leaf for new growth. It's usually a bad sign when the leaves are still plump and drop off for no reason, but yours looks normal:). It's about to go anyways wouldn't worry.

edit: I was writing while Rina was writing. I agree I think it would be good to add more perlite. That's why my plant loved the water during the winter rains. The plant was in a fast draining mix so it could handle and loved the roots constantly being washed with water. It could fill up those fat leaves. They were almost hot pink to because it was cold.

I never purchased any mix for succulents and make my own. I buy chicken grit, perlite and turface in bulk. I use equal amounts of grit and sifted perlite and smaller amount of turface. All succulents stay outdoors from Spring to late Fall, generally unprotected and get 'watered' mostly by rain. I only water if there is prolonged dry period. Drainage of my mix is great and I don't have to worry much about rain.

As it get cooler, I place plastic sheet over most if it rains since cold+wet soil are not too good for succulents. I leave them uncovered if it is just a gentle rain or drizzle. But bunch of jades are without any protection - so far, so good. I don't know where you are, but we are getting down to around 30*F these nights in my location/zone.

rina - are your plants still outside at that temp, just with the plastic over them? What species do you have out there besides the jades?

If succs can stand 30s with some protection, I could have left mine outside for the rest of the year! We don't start seeing days regularly below 30 until Jan/Feb usually.

Problem would be if it rains. Cold + wet is not good for succulents. I have few other plants there: some aloes, 4 cacti, xGraptoveria 'Fred Ives'; Crassula muscosa (one pot is exposed - I am experimenting...), some kalanchoes, probably few more I can't think of - its dark now to go looking. Even couple of spider plants and few others are there...

Your best bet is to research each plant you have for exact hardiness and any other details. Pls. do not leave your plants outdoors because I do - I do not want to feel responsible if you have some casualties :) I will get rest of mine indoors soon - watching the forecast to judge.

I know there are some that will be OK even close to 20*F, but can't tell you which ones.

Thanks - that may be something I experiment with myself when I get more experience. The only one I'd venture to put back outside right now is my Selenicereus anthonyanus (Fishbone cactus), but I'll need to look into its hardiness.
