Wizard npk recipe.

So like 4 or 5 years ago I was planning on making my own nutrients, so I bought wizard npk's recipe for $30. Then a hydro store opened up down the street, more like a shipping facility, I can get 50 lb buckets of maxi grow or bloom for $160, so I never used it. Have any of you ever tried it? I don't think you can buy it anymore and I was wondering why, he was killing shit when he disappeared.
