soulijsam thanks for the comment and reading what I had wrote . This asnwers my questions , the old man I talk with that used to farm said he did flush them but only last 2 days before he chopped them up .Being honest I do like the idea of flushing the nutes out of the medium so she’s forced to use up her stores and clean up but I’ll certainly read into the studies more but past experience tells me heavily fed plants do taste like what I’ve always called “chemical weed” , strong as a ox just a bit rough
Madeingermany I wasn’t meaning when to harvest , I’ve read and understood checking the trichomes to decide harvest . It was more of knowing when to flush as I’d imagine they change from milky to amber pretty quickly leaving little time to flush .
