If your talking about he 800 PPM solution it is for calibrating the meter. It is the wrong solution for calibrating your meter. But if you put your meter in full 800 PPM and your meter reads 800 it's good to go. They come pre calibrated. Test your rez water. if you have seedlings you do not feed for 2 to 3 weeks. You only keep the rez water PH balanced. The co2 pucks are for flowering and only when the lights are on. What kind of nutrients do you have ? Ok I looked and you have GH 3 part nutes. follow the bottle directions or look in the faq's section there is a chart for feeding.. If you are using tap water. check it with your meter if it's over 200 PPM's you need other water. That is hard water and maybe chlorine. Chlorine has one function and that is to kill all organic matter, that's you me and your plants . Some let it sit out in a bowl overnight to get rid of as much chlorine as possible. Sorry man but you got an ass load of home work. It's not rocket science. I'm on my second hydro grow and didn't ask but 1 or 2 questions . I did my home work and found answers from others problems to help me. You got an awsome cab, wish I had it ,it will almost run itself when you get the hang of it.
