Need some help please

I teach 2-12 grade sciences at a school for autism and we are having our first raised beds this year. I’m also putting in a couple of new beds at my house. I’ve been making my beds with the bottom 1/3 woody materials (hugel culture style), 1/3 rich forest topsoil and 1/3 compost. I’m planning on creating a living soil mixture in biodegradable small grow bags (Similar in size to a plastic 3.5 inch diameter pot) to raise seedlings to transfer to the beds. I’m hoping this will improve the soil in the beds overtime. For one experiment, the independent variable will be adding innoculated bio char and another adding rock dust and a third with bio char and rock dust. So, if I have ten gallons of a base mix of 1/3 compost, 1/3 vermiculite and 1/3 peat moss, how much BioAg, liquid seaweed, liquid fish fert., liquid sea minerals, Bioorganics Mycorrhizal fungi (this won’t be in the mix but put closest to the seeds or roots) and molasses would you recommend? I know many of those you would need to know the concentrations of (none are packaged as concentrated and most were purchased off Amazon) but can you give me your best guess? Whatever you all suggest, I’ll use as a constant for my control. I appreciate any help you can give me.
