So I got my sourdough starter going about a month ago, and things were
going very well until this past Monday. Suddenly the starter no longer
rises after feedings and doesn't have a delicious and yeasty smell.
Instead it's smelling like pancake batter (nothing, basically), and
just barely gets a few bubbles after a day. However, this morning when
I woke up and checked on it, there was a thin layer of hooch on top.
Does anyone know what's going on with it? Do you think I need to start
over?

thanks,
