That isnâ??t my understanding

Flushing say for nute burn, is to remove say nitrogen from the soil so that the plant cannot take up any more.

I had to flush just last week because of a potassium lock up caused by my manure which has to much Na+ in it. So I wanted to remove the salts from the soil, nothing to do with the plant.

Part of flushing is washing the nutes off the roots and removing the nutes from inside the plant with pure water . Giving your plants a cycle of plain water pH adjusted to 6.3 may help with lock out if that is what you are dealing with it's pretty simple.
Adding pH'd water to your medium will bring the medium pH close to that level...the idea behind giving your plants a cycle of plain pH'd water between weekly feedings is to reduce the level of accumulated nutrients that can affect the pH in the medium. Also you should be giving your plants ph'd water once a week to prevent lockout.
