hey guys thanks for the info!!! i use to change my res once every 2 weeks but i think il do it every 7 days now!!!!! could you please tell me why its beneficial to do it in the time frame that your telling me and why i shouldnt leave it longer than that, is it because the water goes stail and it turns out to be no good for the plants by laking in nuts or something by the time it reaches 2 weeks or can it corse disease and some deficiecies if left for 2 weeks before you change the res!!!!! thanks oldman60 and bongwaterbob for all your help )

def ever week in flower period but early veg u can go 2 weeks as roots arent developed enough to take up all the nutes. as long as u have air stones in u be fine. check ur ppms and go by that if u are unsure. u should be topping up regularly with ph water too. every couple days or so.

I'd say the res change can depend on which type of system you're using. I'd say a recirculating system should be changed more often then an individual DWC for example.

I stick with once per week, it's to help prevent anything negative from happening to your water and roots. Granted if your water temp is good and you have great airation you should be fine, better to be safe then sorry.
