Tmasmanswered grow question 2y ago I personally try to give few nutrients throughout the plant's life. I only give nutrients until week 6/7 of flowering. In the last days or week, just water, it helps if your reserves are running low, because having cleaner weed with fewer nutrients has a shorter curing time. Well, if you have time to cure, there's no need for flushing. But also, why give nutrients at the end? There's no advantage to it. Do a test with two identical strains, one with nutrients until the end, the other with nutrients until week 7, just water from there on. Cheers and happy growing!
