Any idea as to what is going on with this? It started with a small discolored area on the leaf, which grew in size. Then it developed a hole. The hole is all the way through the leaf. I have not dripped any water, and I know it is not sunburn. The plant is in bright indirect light. I check it for pests daily. I have also checked at night. Nothing. When I brought it home this spring, I did remove some scale, using alcohol. The bugs were located where the leaves attach. The damage I am referring to is several inches out on the leaf.
