So on my second day, my sourdough starter split pretty big and I'm wondering if this is expected behaviour. This is 30/30gr water/fullwheat flour from the first and second day. Here is a picture of the result: https://drive.google.com/file/d/0B_9zXCYnMBMlNXhTOU1vQk9yMjQ/view?usp=docslist_api
It smells really sour, beyond vinegary. Any opinions or tips?
