I hear ya man. I've been growing for 12+ years and I've done side by side grows with AN versus FF, GH, and BC and none of them come close. I'm not as bigtime as you but I am rocking 10k in my flower room now. These guys just regurjitate the same shit the read in other threads about "AN has too many metals" or "AN lies on their labes." It's all bullshit in my opinion. I've tried other and they aren't as good. Most of those clowns either just don't know how to use an advanced nutrient formula; probably just burned the shit out of their plants cause they don't know how to measure ppm; or they have never even tried the stuff and are jsut repeating what they're buddy said or what that closet CFL grower at the hydro store told em.
