One way to tell if the nutrients were processed organically is to look for an OMRI certification on the bottle... that's the organic materials research institute... Serenade carries it, so does Alaska fish fertilizer, TopMax, and a whole bunch of others.
stinkyattic Reviewed by stinkyattic on . is Organic really Organic??? I have read lots of Nutes to be organic. They say organic on the bottle cuz thats what they came form. but how did they extract the nutes from the original organic matter? Do they use chemicals for this? I'd imagine they have to some times right? kd_special Rating: 5
