if you feed from bottles normally and have no amendments in your soil, you're going to continue to need the bottles of nutrient. the AACT itself does not necessarily help the plant absorb nutrients more efficiently in that situation particularly. plants are perfectly capable of absorbing nutrients on their own if they're in plant available forms (which is what bottles contain, readily available nutrients).
AACT is for boosting microbe populations in the soil, which can indeed improve your medium as they will break down matter into plant available forms... but with that said, if you don't really have any matter that is needed to be broken down, they really wont make that much of a difference. What they will do though, is store nutrients in their bodies, and when they die, they'll become food for other microbes, and waste products of microbes can be taken up by the plant in nutritional forms. But when you water in plant available forms of nutrition (from bottles)... what is the point of all of this? bottles provide the bare essentials that plants need for healthy growth, and if you are a good gardener and know how to keep plants in good health anyway, then again... its really an unnecessary step with a bottle fed regiment.
