Root rot or not enough water. The later is unlikely because these things are pretty much bullet proof. I see what appears to be the distal ends shriveling first? I see new growth that looks healthy but ive seen that happen on a jade plant without a root system. I would inspect the root ball. Mushy bad. Light and firm good. Have you inspected for any parasites?

Thanks, I will look at it! No parasites that I've noticed, but I'll check again.

I think the leaves are very sparse, it needs a lot more light. I would cut away the shriveled ends before they cause some fungal infection or something on the healthy parts. What kind of soil are you using and how do you water?

Can you post a pic about the whole plant please?

I agree, need a photo of the whole plant and its light source.

The new growth is not what I'd call healthy---though they are green. I'm not digging the leaves cupped backwards and the droopy growth--that is worrisome. Makes me near certain water and light issues--too much and too little, respectively, but it would be helpful to see the whole plant including the pot, the soil and the light source (direction/exposure).

On the flipside, it is clearly trying to live, WebUser. :)
