WE BEEN IN A DEBATE ABOUT THE ACCURACY  OF E. C. VERSES PPM OR TDS?AN PL?? I SAY E.C. IS BETTER JUST THROUGH MY USAGE. WHEN I THINK THE PPM IS HIGH THE E.C. IS WITH IN RANGE AND PLANTS LOOK FINE MAYBE A LITTLE TIP BURN BUT ONLY ON  ONE PLANT! THE PPM RISE’S AS IT GET’S HALF WAY THROUGH A RES CHANGE BUT IT STAY’S WITH IN E.C. SPEC. KEEP BLAZING THE PATH DUDE
