Today's bake 4-8-2019: Another mixed grain Sourdough with a couple tweaks

Sourdough Bread: April 8, 2019
David Snyder
This is another hybrid bread. It differs from my last bake in the following ways:
I substituted a low-protein white whole wheat for the Turkey Red wheat used previously.
I decreased the total dough hydration to 72% because of the lower protein content of the flour mix. At the lower hydration level, the dough was still significantly slacker than the previous bake. It was also remarkably more extensible.
