With pot culture this simply involves hosing lukewarm water through the medium until it is running freely through. This will remove any salt build up in the root zone. With re-circulating systems such as NFT or Rockwool, it will be easier to fill the tank with fresh water and allow it to circulate through the system to flush the root zone.
Make up a fresh batch of solution, check and correct the pH and Conductivity. Restart the system as before. Keep a careful eye on the new growth which should be normal from that point onwards. It is a good part of routine to flush the root zone once every six weeks or two months as a precaution against salt build up.
