Hey guy's I need help with flushing

im a couple week's away from harvest and was just wondering should i just stop feeding nutes or give my plant allot of water to flush out nutes if so how much and over how long of a period of time i am using a 3 gallon pot

while you are here does adding perlite to soil help hold water or help release it better.....THANKS

never added perilite but from what i have read it helps with drainage

as far as flushing the last 2 waterings i would flush, some ppl dont flush and some flush 2 weeks before harvest, imo flushing the last 2 waterings is good enough

Jorge Cervantes says to use a very weak nutrient solution to flush I use 100ml molasses in 20 gallons of water for the last 2 weeks in an organic soilless system and it works fine good luck I've used plain water too and it works the important thing is to make sure the nitrogen and other mobile nutrients are flushed out of the plant so if your not totally organic stop all nutrients and flush for 2 weeks prior to harvest

thanks guys good info
