This is my third batch and first IPA. I followed my normal routine of cleaning carboys with oxiclean and sanitized everything with star San. This is 1 week after racking to the carboy and it has a white layer and a few spots of mold growing. I don't have a thermometer but I have the carboy in around 55-65*F room. What could this be from? Should I toss it now so I can free up my feementer?
