Grow space details. Things like the medium you are growing in, the nutrient(s) you are using, the type of source water (RO, distilled, tap, well ...), pH of source water when feeding, the lights you are using, canopy/light distance. That kind of stuff.

But without any of those details, I am gonna guess that they aren't getting quite enough P and/or K and they endured a cool night.

What medium ?

It looks like phosphorus def.
Symptoms run along serrated edge and tip - often mimics nute burn. That ph probably interferes with proper absorption- if in soil drop closer to 6.5.

You are locking out . Plant is pulling what it can from leaf ( paleness. )
