Daily ferts (EI or equivalent)
Lots of trimming, swapping out plants, redoing the tank.
Lots of cleaning (water changes, filter cleaning)
CO2 comes from the tank itself. Decomposing organic matter, fish respiration.
Fertilizer mostly comes from fish food, though known deficiencies can be supplied by simple sources, perhaps fertilizer tablets. Daily fertilizer is not generally done.
Low light, perhaps augmented by sunlight through a window.
Specialized substrate only in the sense that it is supposed to help supply the nutrients. High CEC substrate is a very good choice for a low tech tank. Almost like adding fertilizer tablets. Mineralized soil with ferts added is a good way to go, too. Put the work in to make a nice set up that is self sustaining.
Some trimming, swapping out plants, but nowhere near as much as high tech.
Not much cleaning (some water changes, filter cleaning as needed, but set up the filter so less cleaning is needed. No ultra-fine media that clogs so fast.)
Medium tech (If there is such a thing)
CO2, perhaps from yeast or excel
Daily ferts might be used (low level EI or equivalent)
Specialized substrate. (especially in the same sense as low tech. Make the substrate work for you)
Some trimming, swapping out plants, redoing the tank.
Fair amount of cleaning (water changes, filter cleaning)
