I have a pommelo tree in miami florida I just planted. It says it was sprayed last august, probably with a copper compound. Presently theres an infestation of white fly in Miami so the leaves have a sooty mold and some of the white flies. There are also piles of sand at the base of two of the pommelos where ants are. A few of the leaves are curling here and there too. I'm worried I may have citrus greening, though the leaves don't have the clear spots that the pictures online have. All the fruit have dispersed lighter spots when light shines on them. Any idea how to diagnose issues with this?
