Hibiscus help

[Robbyn]

This is the first Hibiscus I have owned. Just wondering about these yellow spots developing on the leaves. It doesn't look like pests. Would anyone know what is causing this? Any suggestion would be helpful. Thanks you.

Welcome to the forum, @Robbyn !

Not an expert and am glad that I don't have this problem, but have googled this for you and hope it is useful.

Light: Hibiscus are full-sun plants. Lack of sunlight can cause overall yellowing of the leaves. On the other hand, if the plant is getting sunburned, theleaves can get yellow or white splotches. Insect Infestation: Spider mites and aphids are two major pests of hibiscus that can cause leaf damage and discoloration.
