I will submit that I don't think of
@GeoFlora Nutrients as a traditional nutrient that you can adjust to 1/2 strength for an auto or any other situation. This is an organic feeding system using the organic feeding circle that involves the microbes, fungi and the roots, in a symbiotic relationship. Using Geoflora, you are putting raw nutrients and the microbes to process them into the soil, and the organic feeding circle will only be able to feed the plants what they need... Always remember that in an organic system you are not feeding the plant, the microbes are.
So if you give a lesser amount of Geoflora (or try to run a large plant in a small container) you are not really giving the plant a lesser amount of nutes by shorting the suggested application amount... the microbes and the plant will continue to communicate as they do and the plant will ask for and receive what it needs, just as always. Because you have put less raw nutrient in there to work with for that two weeks, feeding at the normal rate is simply going to cause the system to run out of nutrient early, nutrients that should have been able to last for the entire two weeks at the suggested application rate. When the supplies run out for this or that, deficiencies arise.
