The best liquid fertilizer question?

I am fixin to enter a credit card number, and backed out cuz I thought I'd get a few opinions first. I was fixin to buy the Big Bloom/Grow, then went shopping some more, and seen this alskan crap. I want the top of the line.

Any suggestions? Outdoor grower, in vegetation state. For now.

I hear people talking about fox-farm all the time. Never used it though, too expensive for me.
