I was telling my friend who owns the hydroshop about how I was going to use h2o2 and he knows what nutes I use and he pulled that up for me LOL woops I said. Also I don't know all the nutes it may affect but h2o2 kills all bacteria even beneficial and some nutes and supplements make little bacteria enviornments that help the plant and then h2o2 comes along and does his job which is to kill all bacteria.
If the nutes are good with h2o2 you're golden, h2o2 is awesome at keeping things clean. And it adds that extra 02, massproducer knows his stuff.
Also I don't know about all the nutes but I'm sure there is some info on the web and some people here who know too...maybe start a different thread so we can all learn from it, like I said I don't know which nutes/supplements are good with it and which aren't.
