My Croton plant has developed small white dead spots on the leaves. What could it be?

Answer

The small white dead spots on a Croton’s leaves, as you describe, sound most like powdery mildew. The surface of the leaves will need to be carefully hand wiped, and the plant should be moved to an area of much lower humidity.
