It's definitely a good idea to flush with hydro. You can start reducing the nutes in the last 2-3 weeks of flower and then straight water for the last week. Or, you can use a flushing agent like Clearex and go full strength on the nutes up until a couple days before harvest.I have about three weeks to go before the chop. When do you usually flush and do i just use straight water? Or should i even bother ?
Get a ppm meter mate. It tells you how strong to make the feed. Number goes up add more water. Number goes down add more nutes. Number stays still or just drops a little bit then its sweet and youll get the best plant you can. From the nutrient side of things anywayswitched to 12/12 8 weeks ago. have been giving them advanced nutes recipe off the bottle since they started and am about to go straight water for another one or two weeks. we'll see i guess as this was my first go at DWC..
are you running dwc jimbob ?Personally i don't flush but there is a lot of debate on this subject... i think the cure is more important, nice grow though buddy
