This might sound dumb ive been looking at the lucus formula and others. And it says .5 n .7 conversion rates. I have no clue what that means or pertains to. I have a hanna HI9813 grochek meter. I can't figure out if its a meter conversion rate...or does it have to do with the fertilizer strength. If anyone could clarify this it would be a great help because i can't use the formula till i know what the hell the conversion rate means. Any help is greatly appreciated. Thank you
Their talking about your meter conversion rates. My millwaukee for example is .7 . If you don't know your rate check the manual or online.
TDS Conversion Factor 0.56 to 0.72 ppm = 1 μS/cm is what the manual said. Does that mean just to be safe i should use the .56 conversion?
