Brown spots on marijuana leaves

  1. Does anyone know what these spots mean? They are starting from the bottom leaves and spreading up. They look kinda burnt I can’t tell if it’s a nutrient burn, calcium or magnesium issue. Please help.

  2. I don't think it's excess nutrients in their water. That will show first in the very tip of the leaves. It kinda looks like a simple splash of nutrients across some leaves.
