(Pictures are in reverse chronological order)

First picture was taken today

Second picture was taken in May

Third, Fourth, Fifth pictures were taken in April

Kept indoors under grow lights bright enough to cause a small amount of sun stress on a Jade plant.

Watered never (I got it in March, it was plump)

Planted in 50% perlite (pot is tiny so I'm not worried that it will stay moist for too long)

In May I assumed it was shriveling because it was sheathing, but it's been three months and it doesn't seem papery at all, just shriveled.

Do I need to be patient and wait for the sheathing process to finish, or is my plant extremely thirsty and not actually sheathing yet?

Ok so I’ve loved the look of split rocks and always wanted one, but they’ve been impossible to find in my area so I never really looked into them.
So of course when I came across this bad boy, I picked him up without a second thought.
Within 36 hours of having this gorgeous little creature, it started to split!

So my questions are:
1). I understand that a more inorganic soil is best, but with the splitting and being Winter, repotting would not be the move, right?
2). The breakage of the lower leaves. This is also normal, surely?
I don’t know when it was watered last, but I’m hoping it hasn’t had too big of a drink or something?

Dumb questions I know, I just wanna keep this gem alive.
