No ardent coco'ers?
colour Reviewed by colour on . Bizarre runoff in coco...?? I use a 50/50 mix of Roots Organic coir and hydroton. I just tested the runoff and I'm getting 6.5 pH and 1500+ ppm. I feed every morning with AN 3 part & CalMag. pH @ 5.6, 900 ppm. What is causing the intense runoff? Rating: 5
