WHAT IS THIS? My ficus, I should say my old friend, has been through four sequential sprays of neem interspursed with copper fungicide for scale. I thought that would be more than adequate, but I found a couple of scale spots just now and several leaves look like they have teeny transparent green holes in the leaf, not open holes though (see photograph).I’ve never noticed this before. Are these teeny holes I’m finding on the leaves indicative of scale returning? I HATE SCALE; it is such a pain in the tutu. Any help is appreciated. 😊💚🪴 PS If the long and the short of it is four more rounds of spray, I am worried about my ficus becoming immune to the spray???
