I just mixed up some FV 20/50 to offer to my boys and it is really yellow. This is the same bag that I have been making mixes from for the last couple of weeks, so not a new bag. All of my other formulas have come out a nice milky white color, this one is more yellow for some reason, even though it is the same formula bag. Any thoughts on this? Could maybe the bag have gone bad? The formula smells fine, the color is off though. Very confused and don't want to make the boys sick or anything. Here's a pic of the last mix in a syringe to the new pic in the syringe when I drew it tonight.
Left is normal, Right is the yellow fresh made earlier today batch.
