My Starter is 12 days old, I started at 1:2:2, after a week it doubled in 5 hours. I’ve now upped it to 1:3:3, will I need to up it to 1:4:4? I watched a video and the guy said to feed 1:3:3 every 12 hours? I just want a routine of when to feed, ratios and how I’ll know when it’s ready to make sourdough pizza with, can anyone recommend a solid routine please…
