Hello. I still believe in flushing despite the report. Some fertilizer company thought they could make millions if they could only get people to stop flushing and keep growing to the end, I'm waiting to see what the next study says. Here are a web site that still believes in flushing: amsterdammarijuanaseeds.com/grow-guide#4 scroll down to Harvest. Lots of good flushing info there. And: edrosenthal.com click on blog and scroll down to Flushing Cannabis Guide. Ed gives both sides of the big flushing question. You make up your own mind about this. Good Luck. Chuck.
