What would cause black spots on the leaves of a newly planted avocado tree? Just purchased an avocado tree from our local Home Depot and today it has black dots on its leaves. Wondering what might cause this.

A photo would aid in my identification but I will give this my best shot. How large are the dots? It is probably insect related and below are pests that would leave black specks/spots/residue:

It could be an avocado lace bug:

It could be sooty mold caused by scale or aphids:

or thrips:
