Mold?

[DaDrafter]

I recently started a fresh fruit watermelon brew. Went through primary fermentation with no problems and have been in a carboy for 1 week today. I am uncertain what it is but in the little headroom it appears that there could be some mold forming. It is white and it could just be residue from the transfer but am not quite sure. Has anyone else seen anything like this? If so what do I do?!?!?!

looks like yeast residue to me.

Worst case is to hit it with some SO2. A little mold won't hurt the wine if it is caught.

I thought the same thing, but being a beginner myself I didn't want to instill confidence if it was in fact mold.
