So i checked the runoff ph of my coco and im finding its going in at 6.0-6.3 and coming out 5.2-5.5, so i have been flushing but it has not changed much. When i first checked the runoff my ppm going in was 750 and coming out 1000 so i figured flush. What do you guys think? Am i on the right path with the flush? The plants seem very healthy and im not 100% sure my runoff ph of 5.2-5.5 is really that bad. This is my first coco run.
