Calibrated the pen and checked pH for the morning. It is now at 5.8 stable. Will check again this afternoon. I have not redone the nutrient mix, I figured why waste it. the mix will be 14 days old on next Monday and that is when I will make a new one and maybe change it every week after that? we will see.
