Starter not rising, please help :(
My mom and I have recently started a sourdough starter, roughly 2 weeks old now, and she bubbles and creates a tiny bit of liquid sometimes but never seems to rise.
I feed her a 1:1:1 ratio with filtered water (room temp) and unbleached bread flour, and we even added a little bit of rye flour in the beginning because we got advice from a friend that it can be helpful (but we only gave her the rye mix the 1st 5 days, she has since only been fed the bread flour). I feed her every day around the same time, it's a little chilly in our house but we even moved her to warmer spots, stuck her in the oven and in the microwave, and still nothing but some bubbles. She doesn't smell like acetone or anything, just what you would expect dough to smell like.
I just don't understand what we are doing wrong. Do I need to feed her more frequently? Or at a higher ratio?? I tried a 1:2:2 once and she seemed to be less active after that, so I got a little scared and went back to the 1:1:1. If anyone has any advice it would be really helpful!
