How often do you guys flush in your hydro set up?

I hear of people flushing all the time in between veg and flowering cycle. How important is it? Do you do it out of precaution or when your medium needs to be leached out? Is this something that tap water users should be more concerned with?

thanks guys

i flush before harvest thats it if i feel like it. if i dont i will taper my nutes down till the last week to 5 days im running straight water and i use tap water.

I put them in straight water for the first day of bloom, then add nutes the next day a little weaker then norm around 1000 PPM. Every time I change the reservoir I give them plain water for the first day giving them a mini flush once a week basically. Last week of bloom they get straight H20.
