> My question then is this: While I am learning the ratio of grains to milk, is it alright for me to change them in less than 24 hours if they look like they need it? Then I would need to increase my milk or decrease the grains until they are doing their thing in a 24 hour period correct?
That's exactly right. Any time the milk turns into kefir "ahead of time" strain then and add more milk than the last time so you don't end up straining more than once in 24 hours. It doesn't hurt them, but it is more work on your part.
