We have had this plant for about a year and very early on saw these white spots on the underside of leaves and on the stem. They were easy to wipe off and I wiped them off with rubbing alcohol. But now they are back with a venegence. I am attaching pics. I can easily rub them off but under the white spot is an area of the leaf that has lost the chlorophyl and looks dead. Is this some kind of fungus or scale?
We really like this plant but we notice that even though it is putting out new leaves, it doesnt look healthy.
