I think your timeline started with the chevron effect, before spotting in the leaf serrations. Then water usage slowed.
This would indicate toxicity. I would try a bit of a flush, and raise PH a bit. Your right on the edge with 6.0 and I'm unsure if your watering at a similar PH and causing acidification.
Can you check the PH of the first run-off?
It would be unusual to see toxicity without feeding, but it's how it looks to me.
You could try a foliage feed on one, to see which direction it heads. Results are fast.
Just asking myself the question here, of if acidification can fix K.
