I don't think so. See if it wipes off with a damp paper towel.
It looks like hard water staining
If you keep your tortoise on a hard surface (cement, rocks, etc.) it could just be abrasion from those surfaces.... Either way it doesn't look like shell rot... If any pus or sticky wet fluids appear around that area get to the vet as quick as possible.
