COM is a good company, selling quality products. I bet that soil is one of the best bagged soil options on the market. I would caution against adding anything to it, short of maybe extra aeration. See how it works first. Don't fear "running out of nutes", unless you intend on using tiny containers this shouldn't be a problem at all.
Rethink using dolomite lime, it has little purpose in actual real professional gardening, more of a myth based canna gardening thingy... I'll ask you why do you think you should be adding dolomite or any other lime to the soil?
Email COM and ask for a copy of a soil test report of that product, they will send it to you most likely this will give you some confidence in the product, and keep you from screwing your self up by adding too much shit to the soil.
My guess is that given sufficient container size, this bagged soil you have will grow an auto well, with nearly only water.
That's just a real strong suspicion I have.
Ok, given the materials you already have and want to use, try a mix close to this.
80% stonigtons
10% added humus (EWC and or a quality compost)
10% added aeration amendment
Top dress with worm castings and this here at the beginning of your cycle would be great:
Lobster and Kelp Fertilizer
I like to mulch anywhere I'm growing anything, indoors outdoors doesn't matter. There's plenty of science that clearly demonstrates the benefits of mulching.
A month of cooking is just fine. Cooking is simply nutrient cycling, allowing the microbial processes to convert nutrients into a form the plants can readily use. A compost tea to moisten your "cooking" soil is a great idea IMO. It makes sense.
If my post leaves you wondering something ask away. I'll either share what I know or scratch my head with ya, lol.
I'm excited to see you grow in this bagged mix, I'm always on the lookout for a decent bagged product to get people interested in growing their weed organically, and nothing's easier than using a bag and water only... If it works well.
It would be cool to see you run one plant in only this bagged soil, adding only water.
Edit: I gave some soil that I mixed up last summer to a friend who had never grown before. He grew a real nice plant in his window, never adding anything but water. I was surprised that it turned out so well. Interesting at least, right?
