heavy water... not enough to make a pond of course, but make sure to use enough that you get more than a drip from the drainage holes of your containers. Once that's done I would say wait 3-5 days before harvest but seeing as yours are good to go, 2-3 days should be enough to get most of the nute flavor out of your gold
