Plants jus started flowering is flushing a myth or do i need to flush 7 days

okay im one week into flowering and my question is do i need to flush for 7 days 5 days ....3 days everyone seems to have opinion but is there any fact so i know what to do for my girls....OR IS FLUSHING A BIG DEAL AT ALL OR JUS MYTH

Really depends on hard chemical nutes,imo. I use organic and i believe in feeding up til harvest. Why starve them at the most crucial time of bud swelling?

Just lower the ppm to like 600ppm for the last 6 days. Give em slightly less than they need so the ppm goes down as they drink water instead of up.

As long as the ppm is going down as the water level goes down, you're not overfeeding them and they won't taste chemically. If the ppm goes up, they're drinking water faster than eating nutes.

As long as your plant is healthy and not glossy dark green, clawing, curled up, or burned, it's going to taste fine, given you cut at the right time and dry/cure correctly.
