People who have grown for 2 year are at the same point you are at, you don't need ''20 year of experience'' to copy what works for others. To fully understand what/why/when/how is a whole other level. Botany alone has changed drastically, never mind the highly misinformed mj side of things. The fact that you are contemplating the details of ''flushing'' clearly shows years of practical growing experience has not put you ahead of the curve.
I'm truly not being a dick or demanding you accept flushing is good/bad, just saying that you don't get to pull ranks.
