That is true in some ways...let me splane lucy: they do over sell their additives in some cases. Because of this newer growers tend to kill plants with their nutes, that being said i have seen people get great results with AN. Not just a few people but many do get good results. But when you look at what they recommend it is easy to become over whelmed. Just keep it simple and get good results, then when you have a few successful grows you can start adding the other stuff one at a time to try and tweak your grow to get better results.
