there are farmers on here that blast the shit out of their plants with all kinds of chemicals & nutes... just as there are other farmers that dont.
the plant(s) will ALWAYS tell you what they need... so learn to read your ladies.
all you need to do : get a basic nute formula (grow & bloom) & then go from there.
i was thinking about moving to house and garden nutes (highly respected) but what i am using is cheap & works like brand new money.
so you know, i run a 6 bucket dwc set up, a dwc cloner, and also roll with the ol' stand by (soil) because i am so damn deft at producing clones.
my nute schedule is based on plant stage, strain, medium used, research, and past experience.
in my stable : quickgrow grow & bud (ebay), superthrive, black strap molasses, esu boost juice, ph down, clonex, hygrozyme, and h202 (hydrogen peroxide)
you should definitely learn to use a ppm meter... i am sure you know it's a very important (hydro) dwc tool.
not to break chops, but bloomer57 is right : study up.
people use all kinds of stuff to grow the wonderful maryjane.
boutique nutes.
cheap shit.
and, everything in between.
it's not what you use ...but how, when, and why you use it.
i have seen quite a few nute schedules around RIU.
being well read, and blessed with the love of research, i never follow the leader... i get all the information i can find, apply it to my grow set up, and make my own path.

can you say "danky dankness" ?
