Organic Soil Mix Help Needed

no problem~ i like that micro approach actually -might keep in mind that many of the thinkings about high P in flower are flawed. the plant uses a nute curve very close to veg in flower (just more of it) are you doing 12/12 from seed/cutting? or do you have veg time?
don't forget to give your complete mix (after amendments) a couple weeks to "cook" keep it moist but not wet (meaning it shouldn't completely dry out during the "cook") 75*F is a good temp for every step of the process
might think about a little alfalfa FPE tea if you veg (only during veg) and maybe a little flower FPE tea for the mid flower boost - mix it very weak since your soil should be fairly complete

No no no.
It's bloody bone fish meal.

You're welcome. that is a great thread with great recipes for soil etc.
Just remember, your blood meal will be active and supply N pretty much from the start. The kelp meal takes a bit longer to start breaking down... maybe several months. The bone meal (P) and greensand (K) will take even a bit longer. So if you are going to make a re-usable soil mix, keep these in mind. Others may have more exacting break down times then what I posted above. Post a question there and get the advise you need.

I would imagine this is what makes recycling soil a bit tougher than it first appears. I should check out that sub thread on recycling soil
lol but the answer would help determine if he needs kelp meal

Here's the recipe I'll be following again:
RECIPE #1
If you want to use organic nutrients like Blood meal, Bone meal and Kelp meal...
Dry Fertilizers:
1 tablespoon Blood meal per gallon or 1/2 cup per cubic foot of soil mix
2 tablespoons Bone meal per gallon or 1 cup per cubic foot of soil mix
1-tablespoon kelp meal per gallon or 1/2 cup per cubic foot of soil mix
or Maxicrop 1-0-4 powdered kelp extract as directed
(OPTIONAL) 1 tablespoon per gallon or 1/2 cup per cubic foot of Jersey Greensand or Azomite to supplement the K (potasium) in the Kelp Meal and seaweed extract.
Mix all the dry nutrients into the soiless mix well and wet it, but don't soak it. Use Liquid Karma and water @ 1 tbs./gal. Stir and mix it a few times a week for a week or two so the bacteria can get oxygen and break down the nutrients and make it available. And don't let the mix dry out, keep it moist and add water as needed. It'll also have time to get the humic acids in the Liquid Karma going and the dolomite lime will be better able to adjust the pH of a peat based mixture too.
With this recipe, all you need to do is add plain water until harvest.
-------------------------------------------------------------
Instead of seperate Blood meal and Bone meal I'm going to go for FishBloodBone mix which is much cheaper for me (thankyou 99p shop), it is also 5-5-5 so well balanced.
My question is - I have made up 20 litres of soil mix as follows (45% Coir + 25% Black Gold + 30% Perlite).
20 litres is (/3.78) = 5.3 us gallons
Should i be adding 3 tbsp of fish blood and bone per gallon, which is the combined amount from the above recipe or is this too much. That would be 3tbsp x 5.3gallons= 16 tablespoons in 5.3 gallons. Baring in mind that:
1. I will be growing from seedling to harvest in it (no veg) and
2. The soil will of course be left to "cool" for about 6 weeks prior to use.
3. Containers only hold about 1ltr of medium
also at 2tbsp per gallon that works out at 10tbsp of Lime to 20 litres, sound about right?
Thanks for your help guys

@Bud-Monster, be very careful with the blood meal, it is a very fast acting source of N and can very easily burn your seedlings, not to mention running out before your grow is done. So you might want to add another N source that isn't so fast acting, Alfalfa meal is a great supplement as it also contains growth stimulants and can be gotten in pellet/meal mix which takes longer to break down. Also greensand takes YEARS to actually break down and release the K, so don't count on it as a valid source of K. I do use it personally but more for soil texture than a K source in a 3-4 month grow. And I don't see EWC in your mix anywhere, it is ESSENTIAL! Find the best EWC you can find and mix it into your soil at about 20%.
Also, I would use real kelp meal and skip the Maxicrop and Liquid Karma (both are just watered down versions of kelp meal) and cost too much. And the 0.5% humic acid in the LK is easily taken care of with quality EWC.

some clacined de might help you out in the smaller containers. seems like a middle ground between vermiculite and perlite.
do you want the NPK to be 15-15-15
maybe as low as ~8 since azomite has cal/mag as well
