any1 tried coco with organic based medium?

Im looking to incorporate everything a good soil has into my canna coco this way I would have to feed only once a week and plants would grow fast. these things would include blood and bone meal,dolomite lime, earth worm castings etc. Has any1 ever though about this before?

Works perfect, i add dolemite lime, worm castings, bio-tone start plus(fungi&bacteria) and Botanicares new Organicare slow release granules(6-6-5 +6Ca)i feed maybe twice during flowering, healthiest plants ive ever had.

i need something not too slow releasing since I will grow for about a week or two and flower right away in 6 inch pots. what should I use and how much should I put? also Im not going to mix the soil in advance so what do u guys recommend. I know bone meal is takes too long to release so what else can I replace it with?
thx

i use coco coir and advanced nutrients organic ferts and no soil at all and plants have never been better just need a lil cal mag in the coco and u never need to worry about the ph if u treat u water properly i water every 5 days
