You can get 20 people to give you 20 answers. Do you want simple 2-3 part nutes or more advanced 10-12 part? Organic or Non? Cheap or expensive? If its your first grow pick something simple and work up from there. General Hydroponics makes a simple grow/flower/micro 3 part that is easy on the pocket and I have read you can use the "Lucas" method and not use the grow at all saving a bit more money.
