The photo is a bit shaky/blurry, but I do not believe it is moldy. It looks like your SCOBY is just getting started. Were it me, I'd give it another week and see if it fills out across the whole surface. Discarding the the tea and feeding it a new batch might not be a bad idea either. When I started brewing Kombucha myself the first batch was not very good, the second was ok, and they just got better with each brewing. The other thing is the kind of tea you use. I tried several and hated some, loved others. I did not care for the green tea when I tried it, but my sister said green tea kombucha was the only ones she could drink.
Currently I'm trying Lipton tea that comes in pouches for brewing a gallon of tea at a time. It has been pretty good in terms of flavor, but it's not what I want long term. I just didn't have any other options at the time and needed bulk tea.

The only other thing that would be bad, would be fly eggs. Do you have it covered with a coffee filter or something similar? Don't use cheesecloth, the holes are too big. I also don't like paper towels because they hold water. Just wait it out and see what happens.
