Oh no echeveria!
Or at least I think these were echeveria.
Does anyone know what may have happened to these poor lovelies?? I went away for one day on Tuesday and they looked fine and happy. When I went to check on these just now (thurs) I was so distraught to see this. These have always been outside; but recently I moved them from a shaded area to the back area, where it gets more sun. It's under a little bit of an overhang so it's a tiny shaded from the sun, but I've never seen anything like this.
There's a neighboring pot with one of the same echeveria about 2 feet away, and that echeveria is fine.
