Sourdough maintainance with minimum starter
I have recently started a new sourdough starter that is approximately 1.5 months old and rises in 6 hours and falls in 12 hours.
I have been keeping my sourdough discard for baking other things but it still turns out to be a lot more that I can handle while feeding 20grams of starter 75 grams of flour and water each.
I do not really want to put my sourdough in a fridge since the sourdough that I discarded all a year ago, which I kept in the fridge was not getting stronger.
I now wonder if I can feed 5 grams of mother starter 25 grams of flour and water each. However, I see that even when I feed 10 grams of starter 40-40 grams flour and water it does not rise and fall as properly. So I am confused if I can do the 5 gram fed with 25-25 flour and water it with an electronic scale.
I would appreciate any help. If needed my room temp is 21-24°C
