I started my sourdough starter 11 days ago. For the past few days it has been smelling like acetone, this morning the smell was really strong. At first I was doing 1:1:1 feedings and then I switched to 1:2:2 twice a day and now for the past 2 days I’ve been doing 1:5:5. My starter only doubled on day 2 and now for the past 3 days it’s been rising about 1/4 of its size. I’m feeling so discouraged, I really want my starter to work but I have very little hope now. I was using 00 unbleached flour and now I’m using a 50/50 mix of wholewheat and 00. Does anyone have any advice?
