Flushing Question

I'm on day 48 of my first AK47 grow. I'm buying a 30x scope tomorrow so I can check the trics, when I think it's ready to stop feeding and start flushing should I completely flood the soil until the water runs clear or should I give it water as if I was giving it a feed?? Just really unsure as to what to do.

you wanna feed water for a week or two.. let it run out of the pots..
