What deficiency or toxicity is this?

I'm having some root problems and pH is a bit to high at 6.7. Is this because, of a new thing? I'm trying to fix the problems. Just lowered pH

PH fluctuations can cause leaf necrosis like that. The last pic looks like the leaf dropped and rested on the edge of the bucket.

Magnesium? My pH was on the high side. But magnesium can get taken from higher pH. So that wouldn't make sense. Altho it does indeed look like mag def.

I'm still lowering the pH atm. I'm gonna wait till pH is stabilized and then see if it gets worse, or better. It looks like they're shooting new roots to.
