The beat advice is less is more. While growing cannabis seems like a daunting task it is not. Do not over think it. Easy grow medium is soil in fact organic super soil (pro mix) requires no nutrient addition until you are past 3 months. You can use tap water with it as well and not harm anything. LST is a great technique to use to improve yeilds. And if you are ambitious fim and top are great to learn as well
