Q.My hibiscus has something on the the leaves
My hibiscus has been looking droopy and has these spots on the leaves . Could it be getting too much sunlight ??
It's possible that the brown patches are sunburn, but I don't think so. Its not exactly characteristic of sunscald which usually has transitional areas of discoloration surrounding the necrotic tissue. Hibiscus is normally tolerant of full sun, unless under-watered and drought stressed.
A photo of the entire plant showing how much of the plant is affected, and the site conditions would help us to determine what is going on. As well as a description of your soil and water management.
