Im new to growing and to cann.com in general. Ive been reading up all of the wonderful information thats provided here and can across a question i wanted to ask to someone with more experience.

Is it possible to have a organic soil mix with enough nutrients to where addidtional ferts wouldnt be neccesary? If not neccesary would it still be possible to use other ferts to perhaps increase yeild? I got this one mix from another thread in here:

1 bag of FoxFarm Ocean Forrest pottting soil
1 bag of FoxFarm Planting Mix with bat guano and earthworm castings
1 bag of Light Warrior High Yeild blend
8-10 quarts of perlite.
1 cup of FoxFarm Peace of Mind Fruit and Flower Fertilizer (NPK 5-8-4)

If someone could gimme some feedback id appriciate it a bunch!
