General hydroponics 3 part. I got some from discount hydro, just a brown box. I like the 3 part cause you can adjust the mix. Started with dynagro 1 for veg 1 for bloom. good for beginners. Most places send in just a brown box. As far as mixes, I'm trying the lucas mix now. Looks like it's working well. Bud blood and big bud did real good on my last grow. I'm trying to find superthrive too.
