    Default Calmag

    So I’m running a RDWC system. Might be being a little pedantic but all my nutrients I’m using are pretty clear. All except my calmag which is pretty dark, looks like the colour of molasses. It turns my mute mix a brown colour. I’d like to use a less coloured calmag so it doesn’t stain my roots and I can see how white they actually they are a bit more accurately. Doesn’t matter too much in the grand scheme of things but something I’d like.

    anyone know of any colourless cal mags?

    Add some h2o2, that'll keep the roots nice and white 👍

    I’m not running a sterile system and I’m trying to get a clear nutrient as I can to avoid staining. Not a big deal if not

    I’m using RO water in RDWC so think it’s imperative. I bring my base up to 200ppm’s before I add my nutrients and boosters etc

    Even using RO water? Everything I’ve read and been told is that I should add calmag back into my water to 0.4EC? My water is 0EC out of the RO filter
