Here are a couple charts to help get you started.

How far is the light from the plants? How old are the plants? What is the light schedule?

Just a few more questions to answer to help find the problem.

Not that I think this is your problem, but I feel all my plants need some dark time. My veg plants are on an 18/6 cycle. With my LEDs the plants require more Cal/Mag. You may be starting to show a deficiency there.

I had a lot of "rust" on my first grow. It was one isolated plant with a different medium than the others. I was watering with an optimal pH, but the soil/runoff pH was very low. It turned out to be a Calcium lockout. Have you checked runoff pH?

It's 6.5

Any chance a few water spots could have got of the leaves with the lights on? I don't think this would be the issue, but it's a possibility that they magnified the light, burning the leaves. Maybe others will chime in.

On a side note, it looks like you may have a bit of nitrogen toxicity, as the leaves are starting to "claw" down, and they look pretty dark green. It's hard to tell from the pictures through.
