Ph issues with foxfarm nutrient line

I just realized that after mixing in the nutes ... Using the full foxfarm line now in flower ... That it stabalizes at 4.5 ph and i cant get it to go any higher any ideas?? Its weird because there really no significant problems caused by the low ph..coco is the medium

All nine of them? They don't all need to be used at once. How many gallons are you making? Are you adding a bunch of cal mag or silica? What ph meter are you using? Does it calibrate well?

What is the ppm of your nutrient mixture? I've found hard-to-move ph means the nutrients are too strong.
