I mixed up a gallon of Garrett Juice per the instructions from the organic recipes. I didn't use but half of it. I had a lid on the container and came back to it a few days later and it looks like it has mold floating on the top. Is that common or did I do something wrong? Is my remaining Garrett Juice O.K. to use?

Hey lady, mine does that too. Just use it anyway, its fine. It's almost like leaving a brew of coffee out over night.
