There's a white discoloration on the leaves of my satsuma orange tree:

I'm uncertain if this is something that needs to be treated, or if it's just residue from a spray at the nursery. It came like this in the mail and does not appear to be spreading.

    In places it looks like a surface coating, but in other places it looks like a discoloration of the leaf tissue under the surface. See if you can wipe it off or scrape it off with a fingernail. – csk May 30 '21 at 02:26

This is either pesticide spray residue or hard water stains. Either way just clean the leaves with a damp cloth.

Your confirmation will be that it does not show up on new growth.
