Flushing is what you do when you have an actual issue. Flushing will stress your plant out. You don't want to stress your plant out unless you are doing it intentionally to get a particular reaction.i shouldnt flush? i thought the salts build up? My water ph is 6.2 and goes down with nutes to 4.7 so i raise it with alot of ph up and i just thought maybe i should flush since im using alot of chemical.
pH UP is essentially potassium carbonate.
