My research on other forums, where there seem to be more folks that have a lot of coco grows experience, tell me that 5.8 to 6 is the best. For me this has always been the optimum for hydro as well; whatever works I say. I just use the regular potash mixture (PH down); I have found that using nutrients to adjust PH makes my PPMs out of whack. Are you using RO water? I have found that if you are, using Cal Mag or equivalent is needed. Watch out for over-watering on coco as well. This can depend greatly on what additional materials (perlite/hydroton/etc..) you mix with the coco. Coco, I have found holds moisture extremely well. my 2p Good luck.
