Proper ec/ppm range for well rooted plants

Can anyone tell me the ideal EC/ppm for my hydro res i am using DNF their chart says 2000 for well rooted plants but ive been reading that it should be about 1000 max on the Grow FAQ. I just bought a blue lab Truncheon nutrient meter today. If anyone has any thoughts on this i would greatl appreciate thanks guys!

right now i followed the ec table from DNF. So i got the ec at 2000 with a ppm of 1000.

Too many factors for anybody to tell you what PPM/EC to run. When I first started growing hydro I had the same questions. Bottom line is that some systems are more efficient than others and everybody's set up is different. My drip systems run at 900PPM and work fine but if I were to go over 650ppm in my aero systems I'd kill everything.

Use your new Truncheon and let your plants tell you. If you measure PPM today and it's 600, then you measure it tomorrow and it's 700, the plants are using more water than nutes and you should back off on the nutes. Conversely, if you PPM is lower today than it was yesterday then the plants are using more nutes than water and you can go stronger on the next mix.

Start low and build up. 1 overnute can ruin everything.

Oh, one last thing. 700PPM is usually 1 on the EC scale.

Convert EC / PPM measurements

By the way...that Truncheon is a nice meter and should last a while. I have a Hanna combo (PPM/EC/Temp/PH) which is a really nice meter but the probes are temperamental. I bought both Truncheons (PPM & PH) to validate readings on the Hanna and the Truncheons need calibrating less frequently than the Hanna. I've heard they last forever.

Ya i know i love that truncheon they say it never needs calibration. and you can clean the tip with unscented vim, For a ph tester i got a oakton it works really nice just have to keep the sensor saturated with the storage solution. Thanks for the tip man! Happy growin.
