The third day curse affected my happily bubbling starter like it does so many. This photo is 28 hours after the second feed, and it grew more in the last four hours than in the previous 24. It darkened. It smelled vinegary and not that pleasant. But no major rise at all. I gave up waiting and fed it again.
I am wondering if temperature is in play. It’s under 75 degrees F in the kitchen and may be closer to 70 than 75. I may need a thermometer. Now I am using nature’s thermometer, a jar of coconut oil (goes liquid at 75 degrees F).
