m0useanswered grow question 8 months ago As autoflowerssucks states flushing does not lower mineral contest in the buds. its just starves the plant.
Flushing to fix a issue in the medium is a good tool should it be needed. Giving just water for the last few weeks or week of life is just fine as well. Dumping copious amounts of water into the medium is not helping. it will stress the plant out and stress causes lack of growth with no nutrients it won't grow and can't recover. The plant is going to be pulling all the energy it has from bigger fan leaves into the buds. mobile nutrients. If the buds are still green and the fan leaves are yellow its the same as green buds and green fan leaves, you are not curing or smoking the fan leaves. A good dry and cure is just as important as a healthy plant in veg and flower.
If double blind studies from cannabis connoisseurs say they can't tell the difference of a flushed and unflushed properly cured weed, then i doubt anyone else can. Tests show the buds content of minerals does not change in any significant way. so whats the point of flushing if nothing has changed in the usable product in the end.
Looks more into how to cure your weed. auto burping and best drying conditions.
There is much more to all this but boiled down flushing is myth for the advertised reasons why people should do it.
Good Luck!
