The new (light green ) parts seem to be OK, so I think the problem is mitigated. You fuck with the roots in any way, and they will do the same to the leaves.
You have issues with one of the metals, maybe copper or iron starting to show. I would up the micros you are using by 10 or 15 percent. That reminds me, I need to spray iron chelate today. I am testing the iron increases CBD claim. Go spray off those leaves with distilled water, don't make them full of fertilisers like that.
