There are two things. One is falling soil runoff pH. This will show in lockout conditions and can be very dangerous.
The other is straight Calcium deficiency, which starts as low leaves looking yellowish as if they need Nitrogen, but they have pale tan dry blotches of irregular shape starting at the edges.
