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

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?

Yellowing some leaves
One of my plants(Quick one RQS) is yellowing some fan leaves. Is she just killing of them because she doesn't need them anymore or Is It some deficiency? The plants look very healthy.

Why are the tops yellowish color?
Why are buds sights so light colored? I just flipped it to 12/12 two days ago. The leaves look good and are dark, but tops are yellowish. It's in a 2x2 with 140W quantam board led at 24". Feeding it Mega Crop at 500 total ppm every other feeding.

Light green leaves in color and burnt tips. Some leaves have brown spots.
Hi guys, can you please help me diagnose the issue. The plants are in BioBizz All-Mix soil. Treated with Bio Grow, Bio Bloom and Top Max from BioBizz. Also BioBizz Cal-Mag in the past week and 1ml of B52 (twice). A week ago I flushed and initially they were looking good.

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!

Nutrient deficiency?
What type of deficiency is this? I think is from lack of nutrients in the soil. This auto been in the 3 gallon pot mixed with Gia green 4-4-4 for a month with just watered. I fed her ff tiger bloom 1 day ago to get her some food. What should I do?
