Question!
15 days +/- from harvest, when do you guys flush your plants?
2 gallon smart pots, 100% Canna coco and Canna nutes.
Also, when flushing with plain pH'ed water, I use RO/rainwater because my tap is so bad (800+ ppm). The RO/rainwater is extremely low, 4 to 7 ppm or 0.0008 to 0.0014. When preparing my nute solution I was told by Canna that I should raise my ppm/EC to 120 ppm/ 0.24 EC prior to adding nutes. I use 2 grams of Epson and between 2 and 3 ml in 5 gallons to get to 120 ppm. It is at that point that I add nutes.
That being said when flushing with pH'ed solution should I bring it to the 120 ppm point. Using pH'ed RO water to flush is damn near impossible without buffering, raising the pH/EC.
What do you guys do or think of this?
