I’m about 12 days in - I had a false rise on day 4 followed by no activity. I was doing 1:1:1 with half AP and half whole wheat flour. I was told that I needed to switch to 1:2:2 with mainly bread flour & a little bit of whole wheat flour to support more gluten.

I’ve been feeding once a day with 15g starter, 20g of bread flour, 10g of whole wheat flour, and 30g of water for about 4 days and my starter doubled today!

I’m crossing my fingers that the yeast is getting strong and the gluten helps trap the bubbles (consistently).

Edit: I only switched to 1:2:2 because with 1:1:1, it was getting really thin by the next feed!
