My sourdough starter is going wrong in every possible way I have been feeding my sourdough starter daily for just over two weeks and everything is constantly going wrong. At first water was sitting on the top, then it started smelling of nail varnish, and now it has a green mould at the top. Should I just give up and throw it in the bin?
If it has mold on it then it needs to be thrown away, you are unlikely to salvage it. Once a sourdough starter goes wrong it's generally not worth your time to try and save it, just start over.
