Well it all depends on what nutes you are feeding and also even more importantly WHAT THEY NEED. If you're using chemical nutes then every couple of weeks are normally good. I have always prefered organic based nutes though as they don't build up toxicity nearly as easily as the synthetic counterparts, so they are a lot easier to use (more forgiving) than stright chemical nutes which is better for the novice grower. This also means you won't need to flush like everyone says, even before harvest! There are so many benifits to organics I can carry oninfo here.. I would first test your tap water for the tds and ph before using it. Depends on where you live, some tap water could kill a plant in days, other flourish.
Good luck
Hey, on another note. I just tested the tap and it is only 40 ppm. that's a good sign i guess.
