How do you adjust PPM?

    I finally got a PPM meter, but don't know how to adjust the PPM up/down.

    I'm using Earth Juice organic nutes in my hydro system. The label only tells how much nutes to use for different growing stages, but says nothing about PPM.

    How do I know how much of each nute to add to get my PPM where it needs to be?

    • WANT THE BIGGEST HIT POSSIBLE?? Vaporize! Because of the cool mist nature of vapor that the Vaporbrothers produces you will be able to take bigger hits and hold them longer than with any bong, iced or otherwise. Take the challenge, but do it sitting down! Support GrowKind by buying Vape Pens and Vaporizers from Vaporwarehouse.

    Add a 1/4 of the amount that the bottle says then check PPM and add more accordingly.

    I have run all my nutes at 1200ppm, but i have heard of others that can't go this high....anywhere from 800 to 1200 works for me
