It depends entirely on your medium, and how much nutrients it holds. For aeroponics, where there is no medium, plain water for 3 days should flush any excess nutes from the plants. If there is some retention to the medium, then you need to flush that well first.

AHHH that makes sense. ..im using expanded clay for my medium, ive had to flush it so many damn times from toxic salt build up . . .so if i flush the medium really good u think 3-5 days should be plenty?

Yep, that should do it. Once you flush the medium, you'll see an overall reaction from the plant. The foliage will lighten in color, and the fading colors of autumn will start to show.

I use clay pellets as well, and they suck up so much water that every week and a half I have to add water because it gets too low for the pump. I don’t ever flush, and all I use is BC 3 part with all the boosters
