depends on when and how its done but lst would be a better option

you may be able to flush with a low ph watter and get it close you definatly want to be below a ph of 7, 6.5 being ideal in soil and another benafit of flushing with a low ph is that a lower ph flush will pull more salts out of the medium. so flush with 3times the water at a low ph and then feed em and let em go just wait til the dried out b4 you do it

Flush with a low ph Water ? How low can the water ph be without damaging anything ? Like around ph of 4 or so ?
