Flushing

Definitely flush if you are using synthetic nutrients. For call mag flush for about 2-3 weeks and for your main nuts, 1-2 weeks of flushing is good. You NEED to flush to remove any salts and chemicals still present in the buds. If not your buds will burn and the ash will stay black instead of turning grey/white. It will also make it much less harsh on the throat and lungs. It will also keep the buds from crackling when burning.

Hi mate, when flushing all you do is starve your plants during the end game, imagine going to the finals in football and having to run the whole match while being starving for a week... it wouldn't be that nice, so just let ur plants grow all they have to grow, nature isn't one to flush anything at the end of flowering either.

I don't flush. Flushing is the equivalent of an urban legend and science does not support it.

I start my flush a week to ten days before my harvest, it works for me.
