i see what you mean, but are their additives really worth that much? unless your using sensi, your gonna need to buy separate bottles of feed or you face deficiencies, if you can get all those nutes from 1 bottle of nutes or a handfull of bat guano/EWC, why pay 50 dollars each for 2-3 bottles just for veg, and 2-4 bottle for flower? if you follow all of their advice, they can tell you some ridiculous things and you can find yourself broke, you could have spent that money on lights, strains, soil, or cheaper nutrients. it all breaks down to what they really need, and what that salt is synthesizing. AN takes what every other bottle of 1 part veg nutes has, and divides it into 2-3 separate bottles, and if you forget 1 of those bottles, you get a Mg/Cal/Boron deficiency(theres plenty of other deficiencies you could experience, just a few i have myself) that could have been avoided. you dont need a separate bottle of nutes for flower, or a bottle of nutes specialized for the first two weeks of flower and the last two weeks, they need the same food all of the time with the exception they want more P and K come flowering time. i dont make your choices, so i cant save you money. take it from a grower who used AN for 2 years, that shit isnt worth nearly as much as they sell it for, its like how they make iPhones for like 30 bucks in china(maybe more, maybe less, i suck with numbers). use it since its at your disposal, but if you try organics or a cleaner nutrient, compare it to some bud grown by AN nutes. i tried it years ago with the same strain, 2 clones. the one grown under bat guano and a bit of bloom booster had much smoother smoke than the clone grown under ANs Bloom and B52.
