  4. I’m not sure I’m in coco so I water to 20 percent runoff I was under the impression that coco is a natural buffer so as long as you ph what’s going in and give plenty of runoff to break down the build up of salts your good. Do I need to ph what’s coming out of my plant? I’ll be watering again today

  5. I mean you can but I wouldn’t, you want to kno what’s coming out compared to what’s goin in that way you kno how and when to adjust things but I would check ec/ppm asap of the runoff
