What if I was to make the medium 80% coco 20% soil, would the seedling be ok for the first 2 weeks? And how strong should I dose the nutrients?( 1/4 of the recommended amount or like 2/4 of the recommended amount)
I would not to mix soil and coco. Mix in 30% perlite with your coco. Soil and coco have different ph requirements. 5 8ph for coco, 6.5 for soil. 1/4 dose will probably be fine. Get a tds pen and measure ec/ppm
same as cooter says about the feed I start with an ec of 0.5 never feeding with plain water and keep your Ph in check I also start all my seedlings in solo cups but in the big pot its the same routine I just find its easier not to overwater in the cups also regarding mixing soil with coco I wouldn't go that route as it causes lots of problems I've been told I also use canna coco but mixed with clay pebbles

I will be growing outside, in a greenhouse.Coco is Hydroponics. You must feed with every watering to 15% - 20% run-off. You do not need to fertigate every day when the plants are young but never let it get dry. The whole idea behind using coco in the first place is to be able to fertigate several times a day to keep fresh "In Balance" nutrients at the roots constantly without it becoming soggy. Start fertigating 2 hours after lights on and stop 2 hours prior to lights out. By the end of the fertigating cycle you want that 15% - 20% run-off.

Ps. I have never seen a good grow here with a 80% coco/ 20% soil mixture. I have seen 80% soil to 20% coco work; where the coco is used to lighten the soil but if you go more coco than that it will not work out well.
