Yea water only approach and from seed. I can get molasses if I need it.
Aight let's get down to it! I would start your seeds in that bio bizz light mix, whatever of that you have left after start your seeds I would mix with your roots organics bags. That'll give you about 58 gallons of soil or more. More than enough to fill up five gallon pots, although I would encourage you to use 7 or 10 gallon pots if you haven't purchased already.
So you've got your 9 cubic feet of roots organics together with maybe some of that biobizz stuff.
Mix in your amendments...I would just do two cups of each of these that you bought:
Alfalfa Meal
Oyster Shell Flour
Kelp meal
Humic acid
Fish Bone Meal
Azomite
Let that all cook.
Hit all your seedling with plain water until they form their first leaves that look like cannabis leaves. Then top dress each seedling with about 1/4 cup of worm castings. Once they're big enough to repot, repot them into the cooked up mix. Put that mycorrhizae in each hole before you transplant, making sure it comes into contact with your roots. After you repot top dress with 1 Cup of worm castings, and retopdress more every couple weeks. Every three or four weeks you should top dress a half cup of kelp and alfalfa meal. And you can just do the plain water thing.
Give me a minute and I'll have a post about what to do with when to use your leftover materials.
