I think some use EC instead of PPM
Mine from the tap is EC 0.4

Sorry guys, I know I haven't gotten back to any of u in a few days and I haven't cared for my girls the way I normally do, my dad is battling cancer and doesn't have long. But I just went down to my room and now I'm completely baffled as to what's going on. I added tap water that I ph'ed to 6.7, and my runoff was 6.5. So therefore that makes my soil ph 6.3 correct? By looking at the chart it doesn't seem I'm locking out very many nutrients. I did just notice I have a bunch of red stems on 2 of the girls. Could this still be a phosphorus def? Or possibly something else? Do u guys recommend I flush em? And sorry muddy, no my soil didn't contain any dolomite and I haven't added any at this point.
Whoa that was a whole lot of info that I've never read up on. How do I check the ppm of my water?
it matches verbatim those symptoms of root rot, could that be it?
get your ph up, I'd flush with a solution of 7.0 for 1 x the pot size then hit it with a 6.7 watering with 10% run off and Check the ph of run off and re calculate.
Rough Calculation Guide:
Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference
If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.
For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5
If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

If you see the chart above at 5.5 in soil you are locking out a lot of needed nutrients......
