You're the one who doesn't seem to understand what organic growing means. The intent is to build a living soil with microbes that process plant nutrient requirements within itself. Who would be foolish enough to flush that beyond required irrigation to service plant water requirements? If the grow medium is properly constructed, it has everything in it cannabis, an annual, will require for its life cycle. I do add AACT teas in vegetation and flowering cycles, but only to supplement the soil microbes, not add nutrients. Many organic growers use only water on their prepared soil with some fine, smooth yields.
On my lawns and decorative plants, I use compost (and clippings on the lawn) to refresh them each spring and do a fungal AACT tea for the lawns so the microbe colonies immediately go to work servicing root requirements. Like someone else said, why fertilize when nature will do it for you.
You seem to be mentally wedded to hydro and/or chemical growing flushes, so I'll credit your punk mouth to a lack of knowledge regarding organic growing techniques. This is the organic forum.
