Weight of sourdough starter?
Hello, I'm just going to ask a possibly silly question.
My starter's total weight is 120g. About three days ago I had doubled the amount from 60g to 120g. After that, I started discarding 60g.
But today, after feeding it, I noticed that there seemed to be less starter. So I weighed it, and found the total weight is 90g!
Why is this? Is it because the starter becomes lighter after rising? So now I discard 30g and that seems to be working. Can I do that? Or is something just wrong with my starter/me?
Thanks in advance.
