    My advice to you would be to not use any organic fertilisers or nutrients in a hydroponic system.

    Ive been doing hydro for years and every disaster ive had had been down to organic ferts, or an additive with organic ingredients.
    I run a sterile system and its been trouble free for the past few years

    Sorry but I don't have any graphs or PDf's, just real world experience.

    The salts in hydro food kill off a lot of the treatments people put in. About the only good thing to put in, is hydrogen peroxide. It's a simple working relationship that's hard to upset.

    There are a few things I will chuck in when needed though. Sometimes I can't use oxy as the pump causes cavitation and runs dry. Then I will use seaweed extracts if they need perking up, or I need to raise the ph because I missed the mark. I have used BlackJack to condition coco for rooting cuttings for a while now, and it's been really good. An actually noticeable effect, you can count in days. That's a humic/fulvic mix that's actually got a decent amount in. I'm certain it's not been damaging. Though it's not powdered, so I can't offer any advice there. Blender?
