My homebrew of sourdough yeast is getting soupy is this ok? It is on day 4.?

Answer 1

It can separate so the flour settles and fluid pools on top. Stir it back into it's former self and it will be fine. Use a clean spoon so you don't contaminate it with other microbes. As long as it's bubbling gently and smelling sour you are fine.

Answer 2

you probably need to add more flour, but keep it sticky.
