The other poster is right; a weak (1/4 strength or less) nitrogen type fertilizer will clear out far more built up fertilizers and salts than plain water. After that you can finish with reverse osmosis water and possibly a clearing soloution.whole point of flushing is to get all the nutes out. use nutes while flushing then why flush?
Honestly, some of you guys need to pick up a copy of Jorge Cervantes "Grow Bible". It would clear up a lot of "pot lore" I read on the web.
