So I'm trying out coco,just lost some plants to slime in Dwc.If I mix up a batch of nutes and try to raise ph slightly it Won't go up,it's stuck at 5.6.But if I adjust the ph of just the water it goes up just fine,only after I add nutes it Won't go up.I'm using gh Micro and bloom and calmag.Is there something with the Gh nutes that keep the ph at around 5.6?

Certainly doesn't sound right, have you calibrated you ph tester? In coco you want a ph of around 5.8 so you're not far off.
Might add a little hydrogen peroxide to your res too. Are you using any certain type of water?
