Why wouldn't I?really? 1700 ppm? thats insane. Way to much bud. I fed pk at 1200ppm once. but my co2 was 1800ppm in a sealed room. I feed around 1000ppm in peat/promix. Thats at peak bloom to. I dont know about coco so i was gonna run 850 ppm in a flood and drain.
I dont get why you would feed that much? Do you see cal/mag def at week 4?
