When you compost, whether its vermicomposting or regular hot composting, you need 2 parts carbon and 1 part nitrogen, browns and greens, to end up with balanced finished compost.
The carbon (browns) have all been eaten as well as the nitrogens (greens) which are now proteins and aminos. If you added your ammendments they are in here too but your alfalfa meal is no longer nitrogen, its proteins that are made of nitrogen. Your coco is no longer carbon, its humate.
You can't count these as carbon or nitrogen, they are now fixed by microbes (composted) into locked nutrients that must be eaten again to become available to the plant.
From here on in, the plant gets carbon and nitrogen from the air. Carbon in your soil is microbe food. Nitrogen in your soil has been converted into aminos. If you still had nitrogen and carbon in your soil, it would hot compost.
To get the compost eaten again you must mix in more carbon, but no new nitrogen. If you add fresh meals it composts again. You want microbes to eat all that carbon and in the process, eat the compost a 2nd time.
The microbes/fungii are supplied, along with some bioavailable (already twice eaten) food, from the used soil. It innoculates your new grow AND feeds it (mix well) until the new soil gets established into a biosphere.
So 1 part compost, 1 part coco so the compost gets eaten again, and 1 part used soil. Then add perlite.
