When to start pre harvest flushing question.

First is it okay to use just plain tap water when doing pre harvest flush? Second do I start the flush when trichomes start turning amber or in their cloudy phase? I really need feedback on this first time I've gotten this far. I'm sure I'm a few weeks away just getting prepared

Yes on the tap water if it's decent...About a week before harvest and it depends on what high you want...and if that plant pic is current...then start your flush in about 4 weeks from now...g/l
Ps I don't flush myself

forget the flushing,like the 49ers, that's gay. and that plant has a long way to go.

Chuck...it's the newbie section...wth is wrong with you?
