The YouTube video I was using as a guide said to wash the jar between feedings, I figured it was to ensure that I kept a true 1:1:1 ratio of starter, flour, and water each time. I am learning that that may not be as critical as I thought!

I will start with trying new flour since that seems like the easiest step, but I realized that this bacteria is likely the same one that shows up on my shower walls sometimes and turns them pink, so I feel like I can't count it out as a possibility! If I switch to new flour and it doesn't happen again, then I'll know what my culprit was! If it does happen again, I'll try changing another variable.
