Flushes required with RO water?

[FemmeFatale]

Is it still necessary to flush plants if using RO water?

The water you use doesn't have much to do with flushing. We flush to get toxins, excess salts, etc., out of the growing medium. Otherwise, some people flush a couple of weeks prior to harvest.

I don't flush my plants at all unless I have a problem.
