My Starter seems to have crashed!
I've had great success with my starter that's a few months old. I've been using a small amount of starter in a jar and would mix 1:5:5 into it the night before to create a levain (50/50 wh. Wheat/White flour) of ~200 ml for use the morning after.
But last night, I used 50/50 rye/white flour, and got no appreciable rise or volume increase overnight. It looks like a batter, as if I were creating a new starter from scratch again. Very disappointing and I'm not sure what happened or what to do. I may just let it rest overnight a second night. I may also take a small amount off and feed it 1:3:3, creating an offshoot.
Thoughts on what happened? Thanks.
