this is correct however if your using mg with continous release nutes. you are gonna risk severe nute burn if you flush. id wait till 2 weeks from harvest then id flush with 4x the amount of water to soil. look for the water to run clear out the bottom if its yellowish there are still nutes in the soil.depending on the size of the pot, u put in 3 times that of water......so 1 gallon pot = 3 gallons of water......
