hydroton and flushing...

It's getting close to harvest time and i have all of my babies in that hydroton clay pebbles with no other medium. It's also on the drip system. My question is how many days before should i begin to flush them. I know some people when on soil flush a week before. But would it be less time on the clay pebbles because it absorbs it faster? Should i flush maybe 4 days before harvest and then day of harvest should water them down one more time with water and sugar?

i would think you would wanna go the full two weeks for taste idk what im talkin about though

anyone else??? I would also like to know if i should starve the plant for a day before i harvest and then drain it with water and sugar.

also, is it best to harvest when the lights are off?
