Hey Folks,
This is another thread in regards to the earlier thread about trying to find a good soil mix that will stabilize PH throughout the Veg & Flower stages...has anyone tried these mixes with success?

Super Soil Mix
Original Recipe, as it was given to me.
1 Bale sunshine mix #2 or promix
2 L Bone Meal - phosphorus source
1 L Blood Meal - nitrogen source
1 1/3 cups Epsom salts - magnesium source
3-4 cups dolmite lime -calcium source & pH buffering
1 tsp fritted trace elements
1/2 - 1 bag chicken manure (steer, mushroom, etc) - nitrogen & trace
elements
- Mix thoroughly, moisten, and let sit 1-2 weeks before use.
Revised Recipe, after several failures due to bad manure sources, I now use the following recipe. Results have been excellent and the clones seem to take off right away instead of having a slow growing settling in period.
1 Bale sunshine mix #2 or promix (3.8 cu ft)
8 cups Bone Meal - phosphorus source
4 cups Blood Meal - nitrogen source
1 1/3 cups Epsom salts - magnesium source
3-4 cups dolomite lime -calcium source & pH buffering
1 tsp fritted trace elements
4 cups kelp meal.
9kg (25 lbs) bag pure worm castings
- Mix thoroughly, moisten, and let sit 1-2 weeks before use.

The mix that I recommend is basically nothing but castings and drainage. I used to cut it with all sorts of things, including soilless peat-based mixes like pro-mix.. but then you're introducing a source for pH problems-- especially when others try and duplicate it but can't find the right brands then substitute with a peat-mix that is too acidic. So down to the bare basics of a mix:
40% castings
30% perlite
30% vermiculite
Addendum...
This is a flowering mix - that is, it is intended for plants or clones that will be flowered. The mix has enough nitrogen to get through a couple of weeks of vegging and the stretch. The grower may need to supplement nitrogen, watch for yellow leaves before 5 weeks of flowering.
The basic mix is:
40% castings
30% perlite
30% vermiculite
For each gallon of soil mix, add:
1/4 cup of high N guano
1/2 cup of high P guano
1/4 cup of dolomite lime
1/4 cup of kelp meal
The problem with high nitrogen guano is its variability. Different guanos break down differently and may burn your plants diffferently. The upside is that high N breaks down quickly and is used by the plant immediately, so that the grower can determine how much is too much pretty easily. Burned tips are just pushing the envelope, but a ram's horn leaf curl indicates way too much nitrogen.
Conversely, high phosphorous guano breaks down slowly. It needs to be supplemented early with an organic flowering fertilizer, like EarthJuice bloom.
When the plants are potted, water them in with a mix containing 1 tbsp each of EarthJuice Catalyst and Maxicrop Liquid Seaweed per gallon of water. If the grower uses B'cuzz, then by all means add it as well. Thereafter, use EarthJuice/Maxicrop, every third watering. Make sure that the plants are fed bloom fertilizer until the fourth week of flowering.
