Everything is amended in my soil and composted for a few months..The teas just keep the diversity in the soil strong amongst the microbes and the populations up so they can do their thing..Granted, sometimes the soil might start running out of gas, like a few leaves below yellowing sooner than I want..So I'll just make a tea to give them a boost and carry them through..For flowering I may make a flower tea, then to my gallon watering pitcher do half water/half tea depending on strength..then to that plain old water before adding in the tea a few drops of say Foxfarm big bloom ( guano & castings ) to give that additional direct feed, like a booster.. I could use just water and the occasional Cal/mag applications and be done, maybe a bloom top dressing but teas are nice.
