If you hardly fed clean water only, and have been pumping the teas, it is more likely you have nutrient buildup, especially if the soil is rich with organic ingredients from the start. Organic nutrients take time, all is not used emedietly when fed. Soil holds onto nutrients and releases them to the plant in a slow release manor. clean waters after a feeding, teas or synthetics, both need some clean water after, because that clean water you can consider is actually still fertilizing the plant, using what is still there in the soil, water as the carrier. Nothin is a for sure right? only you know what you did. If your teas are just worm castings lets say, overfeeding shouldn't happen really. If you are making rich teas with all kinds of things, overload can happen even in organics. and wont show emedietly like in hydro if you burn the plants, can slowly burn for a while. only clean water watering can help the plant work out of it. flushing wont do shit, by the way. Nutrients are bonded to soil and humic matrix.
