Hey Freshwater, i was going back and doing some rereading and i seen where you said you let your tank get to about empty then refill and check EC/PH. How are you keeping your EC down long enough to get it that low?
My EC seem's to keep rising, i'm assuming from water evapurating.
When you flush your system are you just using PH stable water and dumping in each bucket? I kind of think that maybe i'm not cleaning the root's good enough when i flush is why i ask. Might also be why my EC is going up, as my system run's it's bringing back more nute's that have been hanging in the bottom of the bato buckets.
