Spots on leaf

My Mandevilla plant looks very healthy, I have several new leaves. All of the leaves look like they have been dusted with a salt shaker. Very fine white stuff on all leaves but especially on the new ones. Not visible on bottom of leaves but feels a little gritty. Is this a problem?

This could be pests or pest residue. Neem Oil is a good treatment for most pest issues.
