If I were going to grow in pots next year, starting fresh (i.e. I don't have my own compost, or good soil within my property limits, I would do the following:
1. Buy 15 gallon (or larger) felt pots. Thicker walled brands (like Dirt Pot) are better, and worth the cost.
2. Buy bags of organic soil. Where I live, local soil mixes are better than commercial, but I'm in a cannabis capital, so YMMV.
3. Buy organic fertilizer that covers the needs for NPK along with Calcium and Magnesium. That could be as few as bat guano, bone meal, and langbeinite; but I could be missing one. Nutrients are a whole subject in themselves, but starting simple works just fine. Mycellium is important too. Lactobascillus has super powers.
4. Mix your soil and fertilizers.
5. Plant carrots, brassicas, turnips, or other winter crops.
6. Grow food while developing a soil biome of microbes.
7. Harvest food, amend the soil with a bit more fertilizer, mostly nitrogen, and get your girls going.
8. By the time they start to flower, most/all of the amendments in the soil will be used up, so it's time to make a tea that is high in phosphorus and potassium.
9. When it seems like you're a couple of weeks from harvest, quit giving tea, and do "water only" for a flush.
In between all of that is topping, pruning, leafing, etc, but even those aren't required, just very rewarding for optimal output.
