Flushing at the end of flowering?

so I know you flush for the last 2 weeks of flowering.. but how often do you do it everyday? every other day?

Give your plant time to dry the soil out like I flush just as if I'm feeding

WHEN I used to flush, I'd flush once, thoroughly, then switch to straight water, for the rest of ther grow, watering normally. But, now that I have a good grasp on feeding/nute useage, I don't flush anymore, I just switch to straight water, for the last week or so. I can't tell the difference, between flushing, and not flushing, as long as I haven't overfed them,(according to my own guidelines) in late flowering.

yeah i was going flush it once and then just use straight water from then on for 2 weeks.
