Your PH for the nutrients looks fine for soil, but since this is a "super soil" have you taken the PH of a soil sample? I doubt your having PH problems but better safe than sorry.
I'm a little confused about the lights. Is there a single 6 COB fixture or that plus some other lighting?
I'm not saying they're wrong, but 60" for what I'm guessing is 200w (2 COB setting) seems really weak unless I'm missing something. If you can't find the μmols or a PAR map, post the make and model of the fixture and I'll see if I can get you better info.
