Reusing hydro nutrients

It's my first time with hydro. I need some help. I clean my hydro system once a week and there's still alot of food in my resevoir. Would this be alright to give to my ladies in dirt or should I just discard it? Also, is this too often to be cleaning my system out? Thanks for your help.

The plants not only take up the nutrients, but they deposit waste material into the water as well. So, if you use "used" nutes for your soil plants, you will be feeding them depleted nutrients plus waste material.

Don't be so cheap ... ya gets what yas pays for.
