Flushing-When and How

Despite all my efforts I can't find a straight answer ANYWHERE on when to start flushing, everyone says 2 or one weeks before harvest but how do I know that I will be harvesting in a week at that point. One person said start when you see the first signs of amber hairs but I'm not sure if it's credible.

Please help me with this dilema.

i have the same question

i would like to know this as well.

I flush when all of the pistils turn orange or when you see the trichs are to your liking , for 7 days and chop them on that day.

Flushing requires a bathtub and I pour at least twice the pot size through each girl, with pure RO water, Clearex and some GH Flurolicious (cane sugar, molasses..) to add flavor and bacteria food..
