Bio Bizz ,Canna, Or Plagron

All pre mix'd All Dutch .If your in the U.S Check out your local grow store
Im using Bio Bizz at the moment Ph is pretested for ranges between 6.2 6.6
plus the Ec rating runs around 1.7 ideal for seeds and clones then you can
use the All Mix which has more ferts for adult plants again ideal for preflowering stage.
Hope this Helps
