Before you decide on a nute line you should first decide if you're going to run a sterile system or organic. Sterile is easier to maintain and what I would recommend to any new hydro grower, even though it requires the use of RO water. The chances of root issues are non existent in a properly maintained sterile system and doesn't require the use of teas as most organics do. If you know your root system is good and you run into issues, it's not something you have to consider when trying to fix the problem.
I'm no fan of AN products. I've used it in several applications with mixed results, some okay, most bad. Trying it in rdwc was a disaster and cost me a lot of money in wasted nutrients. In ProMix I've gotten better results using GH Flora 3 part, which is far less expensive. If you decide to use AN in a sterile environment be sure and check any supplements you might use to make sure they are inorganic. Some of ANs are inorganic, some organic.
