Question about the nutes I have

I have blood meal, alfalfa meal, bone meal, kelp meal, greensand, azomite, earthworm castings, local compost, coco, and perlite. I've got some mykos and oregonism XL as well. I'm going to be mixing my super soil within the next few days, but I was wondering what I should do if at some point while my soil is cooking I need to get my young plants some quick nutes as my plants are two weeks old right now. How far can I get on just compost and earthworm castings while my super soil cooks? This is the compost I have

Compost and castings work pretty well for young plants, but it depends on pot side. 1 gallon pots will go longer than solo cups.

If you do need to feed your plants, try some alfalfa meal and kelp meal, soaked in a bucket of water for nutrients. For small plants, you probably won't need more than a couple table spoons of each in like 2 gallons of water. Even that might be a little strong.

Or you could take a couple gallons of compost, mix in a half cup of alfalfa and keep, then set it aside. In 3 weeks, if your plants need a little boost, top dress with a few tables spoons of the super compost.

I would just mix some kelp and alfalfa in some compost as suggested above, but i would just topdress the plants immediately with that mixture. there are some soluble nutrients in the compost, and the roots will grow up into the topdressing and your soil food web will take care of the rest.

if you're really in a pinch for some added nutrition, cold pressed kelp extract and fish hydrolysate make great liquid nutrients that are natural and will not harm your soil one bit.
