I have a bit of experience with AN, I'll throw in my 2 cents.
They have an incredibly large line of products, but you only need a few to get good results. Honestly, you could get great results (as you probably know) from just using the sensi a+b 2 part, or the grow micro bloom 3 part they offer. I will say that you should at the very least, use their base nutrients (obviously) and big bud. Their base nutrients are actually quite good, and are priced reasonably well. Their bloom booster big bud is absolutely fantastic, and is also very competitively priced, get it. Now, their beneficial bacteria fungus and enzym line (tarantula, piranha, sensizym) are a nightmare in hydroponics, I speak from experience. Some people use them with success, but the gains are so marginal vs the cost, and there are MUCH cheaper alternatives for a clean root zone such as hydrogen peroxide, or a competitors product like dutch master zone. Voodoo juice, their microbial product, is extremely expensive, but it does work as advertised. It will give you incredible root mass, i've seen it with my own eyes, however, you won't be able to use it in a chemical hydroponics environment with any sort of h2o2 or similar product. To sum up their organics line: leave it for soil.
I could go one by one on their product line and tell you what I think of all of them (as i've used most of them), but honestly, get the base nutrients, and some big bud, and stick with that. Consider piecing others such as the fulvic, humic, overdrive, etc as you go along, but the base nutes and the big bud WILL work, and work well.
Hope this helps!
