I am trying to bring down the PH in my Bio-Bizz coco and It is not coming down??? I am using 50/50 coco and perlite.

My 1/4 strength nute solution is currently running to waste. The water is going in at 5.2 and coming out at 6.2-6.5. I have run 10 times the containers volume through and the ph won't come down.

Any ideas?

Thanks -J
