Forkish starter showing no life on Day 5
Please forgive me (and point me in the right direction) if this has been covered previously.
I'm making (trying to make) a starter according to the directions in "Flour Water Salt Yeast".
The starter went as described at first, but now is showing no signs of life. On day 2 it was bubbly up over the 2 liter mark. On day 3, still active, but didn't make it to the 2 liter mark. Day 4, just a few small bubbles (perhaps from mixing?) and no change in height. Now on day 5, still seems like nothing is going on, mixture just looks like flour water slurry. But it does still have a bit of a sour smell.
I could go into more detail, but perhaps that is enough to determine if I'm on the right track or it's time to start over?
Thanks for any help you care to offer.
