ratio of soil mix so that u just have to only water till harvest

hey guys ...m doing a new grow again...my last grow i screwd it up cuz of N toxicity and hav to start all over again...this time i dont want to make the mistake of over feeding...
can u guys help me with the soil ratio mixture of plant such that from seed till harvest i dont hav to add any more nutrient and just water with simple water and hence help myself frm nt being tempted to over feed my plants...i hav searchd a lot on the net and all i get is real vague answers
what i wanna know is what is the ratio of
coco peat :normal soil: bone meal: blood meal : banana peel : vermicompost
to prepare the soil befor planting ?...
i hav the ratio as out of 10
3 parts of coco for loose soil and moisture retention
4 parts of soil
1 part of vermicompost
and remaining 2 parts mix of blood , bone meal and banana peel ....
u guys think this ratio is good to start the soil of so that i never need to fertilize it again if m jus growing fr a period of 3-4 months
1 month veg and remaining 2-3 months flowering ?
and if i at all see nutrient deffeciency later on
i shall add DAP slowly for little N and P
and banana peel water for K and other micro nutrients ?
thanks guys if u can help me out wiith this...thats all i need cuz the rest is all sorted out for me

there is no answers because there must not be a way. you still interested in hearing ideas

There is no need to reinvent the wheel.

Super soil! Look under organics there is a sub for called subsoil super soil

Read the rols thread in organic section first few pages and look thru a few threads. Don't run subs bs way better shit for cheaper
