IMO Pending on strain, size and mediums most nutrients when applied alone are weak do not have the required amounts of macro and micro nutrients iron magnesium you know the common deficiency symptoms you find on many sites like this in the problem sections ????
micro nutrients get depleted in mediums Zinc Cal , mag etc quickly Also depending on the nutrients there are to ways companies designed them them one is to actually feed the microl bio life which takes longer to actually feed the plant other nutrients have instant results.
I will admit i am a cash cropper and use every possible angle to get the best possible yield from using spray and grow zinc and iron foliage spry to bio boost ,, super b max to superthrive in veg
all nutrient companies lack in there nutrients calcium and mag thats a given and is why so many use cal mag it self on every feeding Same goes with silicates the most abundant mineral on earth and the means of life yet even tho most man made soils have it ,,, It also gets depleted rather quickly
So to think that just Veg A and B or bloom A and B designed for cannabis growing are going to really give you the best possible yield You are setting your self up for disappointment.
all the additives commercial growers and cash croppers add do make a difference and it has actually been proven from adding all types of additives to work below an above plant ,,,,, By using bloom boosters not only does it enhance growth i also noticed shorter flowering times thus being more cost efficient Don't kid your self there are reasons why Advanced , HG and other nutrient companies make these products its not a scheme
