I am not talking about the flush you do before harvest, i am about to empty out my resevoir like i read you are suppose to every 2 weeks to a month to clean out any build up of salts/nutes.
my question is when i drain my resevior and refill it with water when do i add nutrients back to the resevior? do i add the nutes back to the ppm it was before i drained it or do i leave it without any nutes for like a day or so?
