White stuff on Crape myrtle
I have a new Crape Myrtle and recently I found some white stuff (like powder) at the edge of leaves. Not much and most them are at the new leaves. I thought it is fungus but my gardener said it is not. I would like to get a second opinion on what it is. could someone please help?
I got the tree less than a year. It is roughly 6 feet tall and looks very OK. Please let me know if more info is needed and thank you in advance.
