This has some pretty detailed photos of sick plants. I hope it helps.

looks like potassium maybe

Potassium maybe a bit of heat stress too...

POTASSIUM (K)

Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow.

It doesn't look like that too me.

Where on the plants did it begin, the bottom, the middle or on the top?

In which direction or directions did in spread, in what order if in two directions?

What nutes are you using?

In what amounts?

How often?

From the top, looks like HEAT issue maybe lamps are too close

It is heat stress definitely!
What lighting are you using
i bet you can smell the plants its cause they're cooking i just had the same problem
lightly spray them with water from time to time, turn fan up a notch, and back off with lights
should be noticing changes within 2 days

normal for flower at this stage..
