I'm not sure if you mean an all out flush, as in 2-3x the volume of planter... Or "flush" as in, the normal amount of plain water, without nutes, needed for a normal feeding?

The later of the two is what I have been doing.
Sorry I didn't see this before now. About every 3rd feeding I just use plain water, and try to use a little more than normal. Not a real flush, where I would use 10 or 20 times normal watering volume.
