Hi! Something is wrong with my succulents and I don't know how to help them. Two of them have dry white colored spots only on top of the leaves. They both live outside in direct sunlight and get watered every couple of weeks. I live in Georgia so it's quite humid and lots of sun. Please help!
Looks like sunburn. Was there a recent change in the plants' position or exposure? Put those plants in bright shade or at least under an overhang that blocks the midday sun, and they may recover just fine.
