Please Help with Yellow leaves

With nitrogen toxicity the leaves shouldnt be dark Green? Are all getting yellow

Yea, the clawing and dark green indicate toxicity, however, the lower part, where your stripping is occurring, is a lock out. So it's pulling nutrient out of there, Phos, mag.... maybe is what it looks like to me. Mag++ is the standout here, IMO. and probably even Sulfur.

That's why I say foliar it now, cause if I'm right, it could help turn it around faster. But even if I'm wrong, no harm, no foul. Just don't do anymore more than say 2tsp/L, that's all that's really needed. Can be misted once a day, until your out of the woods, and have the bottom back on track.

If there is too much of something, it can act just like there is not enough and you get lockout.

What and how much are you feeding and how often?
