which growing medium to pick?

joeparak said:

i got to choices for growing medium first is coco peat but since there is no good cal mag mix on sale where i live i gotta make my own cal mag mix using CaN and Epsom the second choice is this premade compost but im not sure that the organic matter might have extra nitrogen in them and if any,the slow nitrogen build up would lead to N tox in late bloom
here is the ingredients in the premade compost: rotten leaves,coco peat,perlite,peat moss,vermicompost,rice hull and sand tea
im growing two blubbery bliss auto fems from vision seeds currently one week from the seed and in coco
peat which one should i pick for my final grow medium?

The compost contains no real long term nutrition.
You will not get "N tox" from it's use.
It would fit your bill better but, you'll still need a Ca source in the long run....

Been doing some synthetic runs again lately. I use a 30 day base soil in solo's to 3 gallons. At the final up pot. I use a 50:50 part base and re-amended to "base" levels used soil. This is in a 5 gallon. The plant sets in veg for 8-10 to set roots and is then bloomed. I start nutrient the day it hits the bloom room floor. I watch for signs of high N and adjust the amount given as needed.

Most nutrient lines start bloom feeds too early with too low an N and too high a P.......The plant should basically stay green till harvest.
