Not sure if we are supposed to or not . We change our reservoirs out after week four in flower to make sure any nitrogen used in initial flowering is removed for the end run. We also change out for flush at the end. That's 3 tanks for the duration of flower with daily top off of water and nute.

We use Botanicare in a semi organic [live biologicals] environment. Maybe chem nutes are different but I believe that once a week changes would be a huge waste of nute$...not to mention killing the planet by dumping volumes of water.
