Coco is notorious for mag deficiency issues. Add in LED lighting and it multiplies. The pH looks fine to me. I don't think a .3 difference in pH is going to do much if your showing 6.2 going in/out.
To me it looks like more of an imbalance than a deficiency. The dark green leaves look like N tox but the brown spots and yellowing look like mag def.
I would back the light off some and do clear water feeds for the next few feeds to see if it clears up the imbalance.
Here's a mulders chart to help going forward with imbalance issues. As you can see, too much calcium pretty much interferes with availability of most everything else.
