Bro, in your case, the plant in the photo shows a clear magnesium deficiency. Try using a foliar feed with magnesium, like a magnesium sulfate solution. Or use calmag. pH isn't the issue here.

In my experience with FFHF, my water had to be as close to 6.7 as possible. Always had low ph on runoff. But they usually didn't have any issues.
