When to re-feed my starter...
My starter wasn't performing well at 80% per FWSY guidelines so I decided to change to 100% hydration and it seems to do better. Also user Mini Oven suggested not following a timeline of feeding it every X hours while I'm trying to get it up to snuff. Here is a pic of what it looks like now, 32 hours after last feeding (20g starter, 100g water at 85 degrees, 25g whole wheat, 75g all purpose). It is in a room that is at 75 degrees.
My question: when do I feed it again? Has it peaked? Does 'peaking' mean it has doubled the original volume (which as you can see, it's not close to doubling yet)? It smells pleasantly sour, plenty of popping bubbles on the top surface which is shiny/wet.
