I've been doing a lot of "testing" in my kitchen and today I am happy to say I think I've found the correct ratio of AP to bread flour to whole wheat in my sourdough bread. I believe it was 500g AP, 300g WW, 200g BF for a total of 1,000g flour.
I had started with 3 c water (375g) and about 2/3 c SDS (150g), stirred that together. Added 1 Tbsp + 1 tsp (22g) kosher salt. Then the flour. I did all this in my 6-qt KitchenAid mixer. Let rest 30 min. Stretch and fold every half hour for a total of four times. Cover* and let rise 50%. Turn out on lightly floured board, shape gently. Bench rest 20-40 min. Shape for baking and bake however you normally do it. I don't bake in a Dutch oven any more. I'm still experimenting and learning. But the flavor was great today.
ETA: This recipe made this one big loaf and two smaller loaves in loaf pans.
