Hi and thanks for reaching us
It's no joy when you expect to have lush green plants and to find them discolored. Insects also like lush green plants that are stressed; which make them delicious for them.
What do you see is what we call stipplings. Someone or many suck out the chlorophyll, the green color, one leaf cell at a time. If you look under the leaves, you can see them. they can be, for example, the size of a dot in a newspaper (mites), be white (like a whitefly), have transparent wings (lacebugs) or be green with edge-like wings (leafhooper). It's a fascinating word to discover.
To control insects, you can attract beneficial insects, spray the undersides of the leaves with water, or use insecticidal soap or oil to spray the underside of the leaves. Before using insecticides, you should inspect the underside of the leaves and make sure that there are no beneficial insects such as, for example, wasps, ladybug larvae (resembling alligators), tiny prying mantises or insects are present.
Good luck,
