Best I can tell it's a zinc deficiency caused by high pH.

I watered with plain water with a pH of 5.5, the water seeping through came out to the low 6's.

I assumed my tap water was 7.3, which is common to the area, but it was actually 8+.

It's been 36 hours and it seems like it's getting better.
