I would consider adding fish bone meal and blood meal to that as well as some bat guano (or bird guano) and some epsom salt and some Dolomite Lime (helps stabilize pH) at a minimum to your recipe if they have it available over there. You will also need to cook your soil to allow the microbes time to break stuff down. I recommend getting a tarp, spreading everything on it and mix it up well with a flat shovel. Spray it relatively lightly a couple times as you mix it up with some water and then put into trash cans or buckets with lids (don't want a shit ton of bugs in your dirt) and let it set in the sun for 40-50 days to cook. From there you should be good. Hit me up if you have any questions brother, will be glad to give you some assistance.
Evenin Stank, Pat and friends, I am surprised at all the suggestions for soil additives. Have you got any idea,...at all of what all those things do? For one thing Dolomite Lime is the wrong kind of lime to be using in containers. Dolomite Lime is approx. 50% Calcium, 40-45% Magnesium, and a few other things. That's a lot of Mg. It's made from Calcium,Magnesium Carbonate Not good for your/our purposes. You should be using AgLime, which made from Calcium Carbonate with no Mg. Too much Mg in a soil will create and give you problems you will have no idea why , they are occurring. All kinds of symptoms will appear. Anyhow , if i seem abrupt , it's cuz i don't want growers around these parts making mistakes unnecessarily. Remember , all the stuff you put in the soil , has an effect , sometimes not always what you expect. Cheers Stank , Pat and friends.
