Hey man I am using the HG Cocos A+B and I am also using plain tap water(left out for a few days to vape off the chlorine) Im also using Coco. I just saw your post there in the HG thread and thought maybe we could share some notes. I just started from seed 3 weeks ago. Im at 1100ppm right now.
also dont know for sure if i should be using Cal/Mag but I have heard I dont need to because its in the HG. I have one plant(out of ten) that looks like it might be starting a Cal/Mag deficiency but it might be something else. Ill try to send you some more info and pictures soon but I gotta get off the computer in a minute. Hopefuly we can help each other out a bit if we run into any issues. Im watering to have 20% runoff/waste, are you watering like this or doing something else?
