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 ?
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. :Namaste:
