First grow, how often do you all change out the res? Or do you just keep adding nutes as you see the PPMs go down? Thanks all

Once per week to keep it fresh. I run plain water through for 30 minutes before adding fresh nutrient solution just to wash out any scummy stuff.

You just run tap water through? Im running off a spicket from outside so the temps are a little colder than I would like. If the water is too cold it will shock the plants right?
