It started on a few leaves most mature green leaves.Now it's on every leaf and they are falling off.The leaf cactus is a colorful summer plant with new growth starting red,then turning yellow until it mature into a pretty two toned green leaves.I have been forum hopping looking for someone with any idea of what to do about it or what it is.The stems have started going bare and new growth is slowly stopping.

The last picture was taken before the plant "got sick"
have a pleasant day
