Liquid Levain petered out
My liquid levain was going great gun while I had it out on the counter and was feeding it twice a day. I wasn't planning on using it for a week so I put it in the fridge. I took it out yesterday and refreshed it; it rose only a little and had a bunch of liquid in it. I stirred the liquid in, but it is refusing to grow. Any idea what is going on and what I should do from here?
