I use the GH 3 part plus some additives in hydro and Botanicare in the dirt. The GH 3 part was copied by AN and Humboldt so you know they have to be doing something right if they're what companies are copying. Plus, they're not too pricey and work perfectly. This month I'm trying DynaGro as it's half the price of GH and I'll be using half the number of bottles. When I'm looking at my base nutes and additives, I look at the guaranteed analysis, not the fancy names, claims or sexy glossy graphics on the front of the bottle. I'm no botanist, but I know what works from my 10 years of trial and error, and I'm still trial and error-ing my way to the perfect grow. My issue with AN is their price, not whether they work or not. I just hate to see people waste their money on over-marketed nutes when you can get the same results with cheaper products.
Check this link out for what the macro and micro nutes do when they're in balance, deficient, or in excess:

This type of information is how you bypass all the hydro-store bullshiz. I had a guy the other day trying to sell me boombastic, 4 ounces for around $30. He said the joke around the store was that it worked so well, it's only a matter of time before they take it off the market. I turned the box around and read what's in it and laughed as it was just a more potent version of floraBloom. Considering my current nutrient line has all those macros and micros covered, I passed on his advice
