I think that you might have a problem with mites on your plants, perhaps spider mites. they typically cause the stippling that you see in the first picture. Inspect your plants carefully. Do you see any tiny webs or silk threads between leaves? Pay particular attention to the new leaves at the top of the plant. if the infestation is as bad as i suspect then you should be able to see them but they are very tiny and you would miss them unless you are really looking for them. Also, they tend to hide out in new growth or buds that have not yet opened so spraying the plants may not have been effective.

The last image does not look like a disease. This is a burn that can happen when a droplet of water sits on the leaf in the sun. Try to water the plants at the base and not wet the foliage, that should help reduce the incidence of these burns
