Could you post a few pics of the entire plant or plants?

There definitely appears to be a magnesium issue, but I can't say it's from a lack of Mg. With the soil pH that high, I am guessing you might have too much calcium in the system, which can mess with the uptake of many nutrients, including Mg.

Plants with nutrient problems tend to be much more susceptible to being burned by the light.

Can you bring that pH down? Do you know why it increased?

So you are saying you PH your water? I thought organic we didn't have to if it's inbetween 6.5-7

I think there is some sort of build up I gave them a normal water feeding and phd the water to 6.2 like normal but the run off came out to a 6.7-6.8 it’s never been that high
