I've been using one of the more expensive and hard to find nutes for almost a decade and a half. AB Fertilizer's Super Veg A & B and Super Bloom A & B. It is a liquid from Onterio, Candada. I believe it is the easiest and most reliable product I've used and I used many before settling on this one. I loke it much better than Dyna or GH or Earth Juice or Cutting Edge or ... well... you get the idea.
I hope this helps....
