This happens, most often, with overwatering. Since there are stones on top of the soil, it will be very difficult to know when to water. It is very important to let the soil dry out, very thoroughly, to at least halfway down the container to prevent this.
There is no cure, nor will the lesions go away, but you can prevent further damage and new growth from sharing the same fate by changing the watering habits.
