if I got a cfl closet grow , with a good organic soil mix ,would aact , with castings and mollass, with a kelp foliage spray , and just water be suffice , to do a full grow ? Obv taking light timing and those things into consideration , would I need any other nutes? Wana keep things as simple as I can to avoid nute issues
by good organic soil mix, do you mean a store bought one or something you made yourself? and the 2nd part to that is, what is in this good organic soil mix?
in low light (low wattage) gardens, a light mix may be enough to get through from start to finish with water only as the plant will not require nutrition as quickly as it would with say a 600 watt HPS. the larger the plant, the more nutrition it requires, and some of those bag soils just dont have the juice to feed big plants over long periods of time with no deficiencies.
there will be no nute issues if you indeed have a good organic mix with good microbe populations and proper soil pH. nutrients are slow release, ideally, with water only mixes.
AACT is not a means of feeding your plants, its a way of boosting microbe populations (which in turn break down stuff to feed your plants, but if you dont have much to be broken down, your plants will starve after the organic matter has been consumed).
