Hello, first post here, I'm sure this is just general knowledge, but with a RDWC or UCDWC system when people talk about "changing out the 'nutes'" every week or so, what is the actual process? Do you drain the entire system and refill it with new nutrients and water, or put new nutrients in the epicenter/reservoir? I only ask because I've also heard people saying the only thing they ever did was ADD new nutrients and top off their reservoir.
