I second what DrMota said about the Mother Earth Super Tea that Advanced Nutrients makes. That's some great stuff. Their Iguana Juice is just as good, maybe better. Those are both premium options if you want to go organic.

I've seen quicker, lusher growth with their regular nutrients (GMB, Sensi, etc) but I know some people really prefer organics so those two are probably the best way to go if that's what you like.

If you're not trying to push the limits of what you and your plants can do AN might not be the best brand for you. For me it is because I'm always trying to best my prior achievements. I figure the day I stop trying to improve myself I might as well just dig a 6x6x2 ditch and plant myself.
