I would not recommend "flushing" with large amounts of water the last two weeks, it accomplishes nothing and basically starves the plant. If you want to stop fertilizing a couple weeks before harvest, that's your choice, but why would you want to starve the plant as it's trying to bulk up the buds? As for the "chemical" taste of unflushed synthetic nute plants, that's Broscience. There is absolutely no difference in the nutrients absorbed by the plants from an organic or synthetic grow. The synthetic nutes are bonded to a a salt (not table salt) when mixed with water the nutes dissosociate from the salt and are immediately available to the plant, the remaining "salt" is not absobed by the plant. In an organic grow microbes are responsible for breaking the compounds down into forms usable by the plant, but it's the same nutrients the plant takes up. There have been tests of plants that were flushed vs unflushed and the only diffence is a slight decrease in the amount of iron in a flushed plant. In blind taste tests unflushed buds were preferred.
