Getting the correct balance and ratio of the ingredients you mention is not easy

Please don't think I'm dis-ing OG's recommendations. Nuttin but respect in that vein. I'm only relating what I have observed and experienced. I used 2T of high N bat guano (11-4-1) per gallon of medium for years and never experienced nute burn. What I did note was that over time, the plants consistently developed the eagle claw leaf deformity associated with over fertilization. Cutting back on the guano helped. I now use alfalfa meal (2-6-1). Double digit NPKs are unnecessary and even problematic in my experience.

Everything we do has consequences, and the consequences of not enough slow release N means applying quick release nutrients in the form of tea.

You aren't likely to screw up a tea. It's as simple as putting a quarter cup of compost, worm compost, guano, or a combination of them all into a gallon of water and letting it brew for a few days. Bubbling is not necessary, our grandparents and their grandparents before them all brewed non-aerated (fermented) teas to feed their gardens, and they grew just fine.

There are a couple ways to do it....Often, I just put the organic material in a gallon milk jug, fill it with water, cap it and shake it up real well. Then uncap it and let it sit. Agitate it a few times each day, and let it brew for 2-4 days. Dilute it 1:1 with plain water and apply. No nasty odors.

Molasses - good stuff. Blackstrap is best. Mostly it feeds the microorganisms which make the existing nutrients more available to the plant. So indirectly, it boosts plant growth. A couple T per gallon of water. It also imparts some sweetness to the cured bud. I use molasses at transplant and every few weeks.
...the kelp meal in your medium is doing the same sort of thing (feeding the microherd) as well as providing natural growth regulators...

Nitrogen Transformations

Nitrogen, present or added to the soil, is subject to several changes (transformations) that dictate the availability of N to plants and influence the potential movement of NO 3 - to water supplies.

Organic N that is present in soil organic matter, crop residues, and manure is converted to inorganic N through the process of mineralization . In this process, bacteria digest organic material and release ammonium (NH 4 + ) nitrogen. Formation of NH 4 + increases as microbial activity increases. Bacterial growth is directly related to soil temperature and water content. The ammonium supplied from fertilizers is the same as the ammonium supplied from organic matter.

Ammonium-N has properties that are of practical importance for N management. Plants can absorb NH 4 + -N. Ammonium also has a positive charge and, therefore, is attracted or held by negatively charged soil and soil organic matter. This means that NH 4 + does not move downward in soils. Nitrogen in the ammonium form that is not taken up by plants is subject to other changes in the soil system.

Nitrification is the conversion of NH 4 + -N to NO 3 - -N. Nitrification is a biological process and proceeds rapidly in warm, moist, well-aerated soils. Nitrification slows at soil temperatures below 50 degrees F—thus, the general recommendation is that ammoniacal (NH 4 + forming) fertilizers should not be fall- applied until soils are below 50 degrees F. Nitrate is a negatively charged ion and is not attracted to soil particles or soil organic matter like NH 4 + . Nitrate-N is water soluble and can move below the crop rooting zone under certain conditions.

Denitrification is a process by which bacteria convert NO 3 - to N gases that are lost to the atmosphere. Denitrifying bacteria use NO 3 - instead of oxygen in the metabolic processes. Denitrification takes place where there is waterlogged soil and where there is ample organic matter to provide energy for bacteria. For these reasons, denitrification is generally limited to topsoil. Denitrification can proceed rapidly when soils are warm and become saturated for 2 or 3 days.

A temporary reduction in the amount of plant-available N can occur from immobilization (tie up) of soil N. Bacteria that decompose high carbon-low N residues, such as corn stalks or small grain straw, need more N to digest the material than is present in the residue. Immobilization occurs when nitrate and/or ammonium present in the soil is used by the growing microbes to build proteins. The actively growing bacteria that immobilize some soil N also break down soil organic matter to release available N during the growing season. There is often a net gain of N during the growing season because the additional N in the residue will be the net gain after immobilization-mineralization processes.
