is it the runoff that you messure to 6.5?
"You must use a PH pen to measure the PH of your solution. PH is very important in the coco world just like hydro. Because coco is so closely related to hydro, the PH in coco must be kept at a gernaly ph of 5.8. I normally keep mine to around 5.9-6.0 just to give a buffer area incase anything were to go wrong. Gernally coco will work fine in any range of 5.6-6.4. But that range is also depending on the plant."
what light do you got? if its hps 30 cm doesnt seem that off, but i would try to put it alittle closer, just be careful with the heat!
