My Starter Smells Like Acetone
My starter is 7 weeks old. I've had this issue for a few weeks. I know this is because it's underfed but I can't seem to fix it. it's very active. It rises and fall, and has lots of bubbles. I had another post on here and someone said to 1:1.5:2 (starter:water:flour) once a day. I have been doing that by the next morning the smell is back. it does seem to be a bit better but still noticeable. It's never passed a float test and doing this method the starter is very very sticky and thick. What do I need to do to get ready for baking? I assume I shouldn't bake with it smelling like that. Once I fix the smell how long until I can move it to the refrigerator and feed it weekly? any information about that part of the process would also be awesome.
Thanks in advance
