in natural/organic soil grows the most important thing is not having the correct balances of npk and micronutrients.. just make sure they are there in some amount. and that u have diversity in your soil life (microbes).. which with worm castings, guano and humus and such, u will. then give em some carbo (molasses, sucanat, etc..) once a week to feed the soil bacteria.. because u arent really directly feeding the plant when ur doing proper organics. ur feeding the soil bacteria, which break everything down in the soil into a usable form for the plant, then the plant eats that. humic and fulvic acid help with the uptake of that which has been broken down. the only difference is humic acid has a ideal ph range, where fulvic acid functions across the whole ph spectrum.
i think a great idea would be to brew a tea with just molasses, worm castings, alaska humus, a tablespoon or so of azomite, yucca extract and humic/fulvic acid.. and dose the plants with that once a week.. and then stop for like the final couple of weeks of flower.. that will ensure your plants are thriving in their soil and using eveerything to their maximum potential.. i would do this except i just do not have the time anymore to do so. using unchlorinated water will be ideal if its easy for u to do so, but if u cant its not fully necessary.. results will be good regardless.
