i think the onlyway you will ever no the best is to try every line of fert an,canna,ionic h,an,g etc etc in ebb an flo with same strains an same ppm,ph throught out,then try every line in dwc same ppm strains ph etc carry on through all the systems then move on to organic an soils too too much, for one person would take years but thats the only way, word of mouth dont count as john over there can grow 5lbs with flash light an pissing on his plants an bob over here use top quality nutes lights water chillers scrubbers etc an grows an oz,jus because you used it once an you did not achieve what you see in the ads donkey dick buds does not mean its shit 99.9% of the time its the strains or farmer wrong ph wrong temps you know the score you need to work a couple of grows first to say that its shite,another think i love is when peeps never even tried it an start hating it because the word of mouth john says its shit so its shit, personally as said it seems to work with me plants look so much healthier the only things i use is the sensi grow a+b for veg an bit superthrive an flower sensi bloom a+b, overdrive, hammerhead an bigbud(not at same time big b an hammer h) thats it i dont belive you need all of them an i dont think you need to add exactly whats on the bottle 1/2 or 3/4 strength if you can push more with out problem then all is good diff strains hardier than others, i dont know why but if you constanly use same strains an dont achieve try another strain to see if they like better half of you all say it yourself ar my chemdog is a nitrogen whore using AN loves it then tried a afgan kush with same nutes as you were using with chemdog an your afghan has nothing but probs then start saying AN is shit so you switch to canna an afghan love the canna so start a thread canna is the best an so on hope you see what i am trying to say most of time strains an farmers i think the question should be which strains like canna,an,hang,ionic botanicare etc an which love both that way people could buy the nutes for the strain i am probably chattin shit buts thats my thoughts peace
