Sorry if I too misunderstood you.
born hit on the important parts. So..I won't repeat all that.
Here is a good mix that a lot of pro's use. Or at least something very similiar.
Start with a base of soiless mix....like Peters Pro Potting mix. All it has is Bark, sphagnum peat moss, and vermiculite.
Take 2 parts of this. Add.....1 part perlite, 1 part vermiculite, 1 part earthworm castings, 1tbs lime,1 tbs blood meal, 1 tbs bone meal. These figures are for a gallon of mix. This will give you a good airy medium that is loaded with goodies. This is a soiless organic mix.
I will reiterate about using chems. It is VERY easy to burn the hell out of your plants. You MUST use them diluted.
Are we getting closer to what you want?
