Thank you
@Waira for clarifying these terms "flushing" and "cleansing" for all of us. LOL I was reading through
@pop22 's article on why flushing is for fools and I kept wondering why I will not understand why it wouldn't make sense with all the science that giving the plants just plain water makes them have to use their extra stored nutrients. Now I know I all this time I have actually been doing cleansing at the end of my grows. Just giving them plain water to the reservoir for couple weeks as they keep drinking it, eventually diluting the solution to mostly water.
It was a good read after I understood what is meant by the term "flushing".
