I think it is too much Nitrogen or plant food, that can mimic light burn, it could be light burn if you are using a strong lensed light with a bad lens if it is just a few leaves it could be lensing. It really looks like overfeed to me though. It has been a long time since I grew, but it's all coming back really fast, LOL> Good luck!

I'm in coco/perlite under a MH at 400w approximately 17inches or so from the top of the canopy.
The markings are on random leaves on 2 of 3 of my plants and not very consistent. Im feeding at about 910ppm 5weeks into veg.

Looks like something else is going on ....
3 finger leaves. Have you been running irregular light cycles ? Or other stressors.

I notice the light turn on a hour early a couple weeks ago and this was using a mechanical timer. I've been watching it closely since... humidity hovers between 40-55% and temp at 18-28 degrees celcuis

maybe too high ppm, depends on size of plant.
