the only time i looked at the back of my AN bottles for guidance was the first time i used them. i had to find my own concoction. so the way i measure mine is by a ppm meter and the ratio ive finally figrued out that works for me. i do a 3-1.5-1 ratio g/m/b until its up to 1000...at this stage that is. honestly man people knock it a lot cuz of the salts that are produced and its potency, but iv got it under control and im seeing fantastic results just from the g/m/b from AN. i WILL be switching before i even finish my first bottles tho. Earth Juice is callin my name. AN is fine until you have some sort of deficiency that ur initial A&B formula cant fix. Then the bottle you'll need is like 80 dollars. which is craziness! hope this helps.
Thats why i switched to canna. 1/3 the price (cept there boost) but a LOT less additives. I used AN for a year and a half never really had a problem with them just that when i did run into a problem the additive to buy it cost a arm and a leg. Had a LOT of sucessfull grows with AN but the ph always seem to drift had to adjust it 2 3 times a day. Now i use canna i ph maybe once a week spends a lot less on the nutrients. And i seem to be having even better results with a LOT less additives/ And for the past year ive been using them i have seem to spend less time in my grow room because everything always seems to be on tract.
