What does a cannabis plant require and why? Informative breakdown

Hey everyone,
I am stepping out on a limb and asking a very broad question in order to gather feedback from multiple people. This will not only be helpful for myself but also for anyone else who's has questions. I also think this is a fundamental question that is often over looked.

"Light, food, water"......no shit?

This is not the type of answer that will be helpful in this thread. Hopefully we have all reached this point.

Explanations/information on:

Microbial colonization in soil and what it promotes?

Molasses uses and intended outcomes for roots? How to combine molasses with nutrient schedule and why?

Bloom enhancer ingredients and how they affect your plant in order to give you larger yields? Potassium and phosphorus are typical in these products, anyone know why? What they do to our plants?

Preferred methods and descriptions of what, how, and why you do what you do is also welcome..

I just figure this will help me and others learn something.

Molasses is a good, quick source of energy for the various forms of microbes and soil life in a compost pile or good living soil.

In addition to sugars, molasses contains significant amounts of potash, sulfur, and a variety of micronutrients. Because molasses is derived from plants, and because the manufacturing processes that create it remove mostly sugars, the majority of the mineral nutrients that were contained in the original sugar cane or sugar beet are still present in molasses. This is a critical factor because a balanced supply of mineral nutrients is essential for those “beneficial beasties” to survive and thrive.

One final benefit molasses can provide to your garden is it’s ability to work as a chelating agent. Basically saying that molasses is one of those substances that can convert some chemical nutrients into a form that's easily available for the plants. Chelated minerals can be absorbed directly and remain available and stable in the soil.

Dosage is usually given at anywhere between one teaspoon to one tablespoon per gallon of water every watering.

Phosphorus is a very key nutrient in both vegetative and flowering stages of life. Phosphorus helps your plant to utilize all the light energy it receives into new growths, leaves, stems, and of course those beautiful flowers. Also, much like nitrogen, phosphorus aids cannabis in helping root growth and helping to speed up the metabolism.

Potassium aids in photosynthesis hand in hand with phosphorus. Also helps with bulking up stems and helping to keep the plant "sturdy". This nutrient also is a major contributor to helping your baby girl become more resistant to disease, fungi, and also help her retain water.
