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

I cant see the whole plant, but from the picture it looks like nitrogen deficiency.

Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?

What could have caused this to happen? Leaves are bending and middle pice of the leaves start to have a little yellowish tint (very lightly) if I can see it correctly. Overwatered or a nute-deficiency?

Northern lights with yellowing leaves Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!
