Kentia Palm White Patches On Some Leaves

Question

My Kentia Palm which appears to be thriving has nevertheless developed some white patches on several of the leaves. These white patches appear to be embedded in the leaves ie they do not wipe off. There is no fungus apparent on the soil. What to do please?
