newbee in growing-NPK mixture for outdoors

Im starting my first grow here in portugal, i know bits but as far as the NPK ratio is concerned i have no clue. I have read up about it and found that different types like different mixtures, like the blue dream i have likes more nitrogen unlike the california kush. So I am looking for a mix that will do well for all. I will add more to the ones i know but i need a general good NPK mix for outdoor grow. I am looking at the atami Bcuzz a + b and a root booster. I dont know if they are any good not, so if anyone knows if they are or not please let me know.
