Looks like there’s yellowing in between the veins of the leaf to me. That or the lights making it look that way. Anyhow that’d be magnesium deficien

Light burn I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Yellow dot on the leaf.Yesterday I watered with fertilizers. The dosage is 0.8 grams per liter. PS in the area of 5.5. The instructions say 4 grams per gallon. 1 gallon = 4.55 liters. Everything seems to be correct, so I do not understand what the problem might be.
