How long to flush

How long do you guys generally flush with fresh water before harvest? I should be harvesting in about a week from today and I flushed once and have only been watering with fresh water no nutes for about a week. Is this totally goin overboad?

1-2 weeks is usually enough time for flushing or you can do the emergency flush method which I find the best and it only takes about 3-4 days.

I flush for 1 week!! seems to work well.

so what happens if you start flushing but your buds take an extra week or two longer than you expected, so you end up flushing for like 3 weeks? is that cool?

then you flush for 3 weeks when the hairs are around 40% brown i start flushing

The color of the hairs is not the best way to tell when to flush, you need to check the trichs.

Also 3 weeks of flushing is fine especially if you are growing in soil.
