I hear ya Joe! Sorry I missed the conversation...anyway, I’ve flushed with water (both tap and RO) and also things like final flush and another one that I can’t remember. What I’ve found is that the more you flush the better the smoke after a good cure. Leaving too many nutes can cause the weed to burn black and extremely harsh. Not that nice gray ash that we want.
I’ve been flushing for 7-14 days in DWC lately, depending on the plant and how much fade I can get on the larger fans. The fade tells me the plant is done flushing IMO, but every plant is different as we know. For me, normally, flushing begins after I start seeing the trichomes look the way I want.
I’m definitely no expert, but I learned the hard way that a good flushing is mandatory for good smoking.
