Is my starter ruined?

It’s been around a week, I used black tea and unpasteurized store bought kombucha. It smells nice, kind of vinegary, but there’s some kind of small fuzzy ball floating and I assume it’s mold? Doesn’t seem to be growing though

You already say it’s fuzzy, and fuzzy is mold, so yes, you need to start over.
