Start Flushing now?
Hank dank im not sure at all lol but i like the way you workif your wanting to "flush" now id suggest just continue watering your plant with a 1 tablespoon per gallon mixture of molasses, it will make sure your plant uses up the remaining nutrients in the soil while feeding the micro organisms as well, happy soil = happy plants.
