Anyone know what might be going on here? I've had it a little over a year, never repotted or moved from its spot.
The leaves look strange to me.

Lighting...water...needs re-poting.
Or bug damage. Probably the latter.

I see a white stuff there, get a Q-tip and dab with some alcohol to remove it. Check the underside of the leaves, if it is there too. Other than that, the plant looks okay to me, though too deep green which indicates it is getting limited light. Don't know where you are located, in my area, Fall time is good growing time for my jades, they like the cool temps and good light, so there is new growth coming usually at the center tips or anywhere up and down the nodes of the trunk or branch.

If your only concern is the white stuff (mealybugs) on the tip of the stems, then you do not need to relocate it, repot it or otherwise change your watering routine. We cannot see most of the plant so it is hard to tell how well it is doing overall.

Treat the mealybugs by mixing 5 parts of water with 1 part alcohol and spraying the entire plant so that all leaf and stem surfaces are dripping wet. If you just treat the ones that are visible, you will miss the translucent juveniles that will later reproduce and the problem will return. One thorough spraying should be sufficient.
