No reason to flush, I have a bottle of final flush that I thought I would use but I won't. Just give tap water for the last 10 days or so and you will be fine.
i use fox farms sledgehammer. here is my method...
i grow in 4 gallon buckets. rule of thumb on flushing is 3x the container size you grow in will be needed in water so that for me is 12 gallons. i start with the first 2 gallons mixed as directed with sledggehammer. then i use ten gallons of oxygenated, dechlorinated water with a ph of 7. i starve the plant of water the last day or 2 makes drying a little faster. hope that helps bro
So your saying i dont need to rinse the roots atleast 7 days before i harvest them to make sure there isnt any additives or nutrients still in the bud of the plant?
or were you saying there is no need to use something to help rinse the plant of the chemicals that i prefer not to smoke?
