I picked up a Kalanchoe at the beginning of the summer without knowing anything about their care. I ended up over-watering it at first, which made it leggy and it grew many smaller leaves than it originally had.
But the mystery to me is a dusty covering on nearly all of the leaves that returns quickly when wiped off. At first I thought it was only dust, because I was behind on dusting my plants. But the dustiness returns much more quickly on the Kalanchoe than on a neighboring Christmas cactus.
Here are some photos of the leaves and the full plant:

What is going on with this plant, and can it be saved? Or am I better off starting over next spring?
