It could be spider mites. Can you take a pic of the leaf?

Here is a link that might be useful: spider mite

I suspected spider mites, but thought they did most damage on the underside of leaf. I sprayed some neem (rose defense) on the plants a week ago for some minor rust and aphid control. First time I've used it as I normally just use soapy water on aphids.

Just planted several citrus... perhaps I imported the problem with those nursery trees since they also have the damage. Spotting is similar to one of the pictures on the site you posted, but not early as bad and only on the top surface.

I'll try to get a picture.

Hi,
the white spots and black spots on the hibiscus, nothing underneath. I did the daily spraying with fungacide, did not help. I Took a leaf to my nursery guy. said..it is a disease, but is too much water (rain) then got hot, few days. Course we did not water, felt enough water! The heat took the water out of the leaves, caused the white spots. Has damaged the cosmetic look of the bush. Nothing can be done, eventually leaves will turn yellow and fall off. When a normal watering starts, will be ok. Said that ivy get this same problem. ruins look of the foliage.

Now on the hibiscus, I am waiting for the buds to produce new flowers, I am hoping this condition has not ruined the flowers, will not know until they bloom. I have 4 hibiscus with this condition.
