most bloom nutes do the same thing people usualy just buy whatever the local store has. once you learn more about micro and macro nutes and what a plant needs at certain stages of life then you can get fussy and mix and match nutes.
basicaly for veging you want high nitrogen. then for flowering you want the phosphorus the highest and the potasium next and then low nitrogen numbers and neer the end you want no nitrogen. then the last couple weeks straight water.
i use botanicare, worm castings,bat guanno,sea tea.
the nutes dont make the smoke any better some will increase bud structure or size by feeding more nutrition but quality is in the genes and is not changed by nutes.
i know someone that works at u of bc and analyses marijuana for med patients and also has his own line of nutes. it takes more than nutes to change genetics so dont be fooled by advertising
