Looks like it's on the new growth. My guess it would be Zinc deficiency.

This looks like a classic case of light burn the top part of the plant seems damaged which is close to the light source.

After some googling, it seems to match? But the yellowing on mine seems to be very concentrated just on the tips.

Blätter gelb und fallen ab Blütewoche 9
I'm really worried about my plants right now, a lot of leaves are turning yellow really quickly and falling off on their own even though I'm fertilizing with every watering. Should I fertilize even more and water more often? The buds look good so far, but there are still more white hairs than flowers.

Start feeding two weeks into (auto)flowering?
Two autoflower plants around two-three weeks into flowering. One plant is getting light green and yellowish leaves that feels papery. I have not given any extra nutrients (just nutrient rich soil to begin with, a little over 20 liter). Should I start feeding now? Or is too late?

Why is one leaf yellow AND shiny?
Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?
