Difference in EC numbers Bluelabs Truncheon VS Digital TDS meter.
DreamCatcherstarted grow question 4 years ago
Can somebody describe what they can see in this picture? I only received it a few days ago, and since have been watering based on what the Truncheon tells me, but few days later i see a toxicity on my plant, and testing it against the Digital TDS meter shows me diff numbers(?)

I have to say after reading online the manuals for both meters, both have embedded termometers to work under any temperature, and they come factory calibrated so I suggest this:
1) Clean them both very well with distilled 7.0 ph water.
2) If you're using rechargeable AAA batteries with the Truncheon, that's the issue, replace them for regular batteries.
Measure again, stirr for a moment and let them stabilize, hopefully the readings will be a lot closer than now!

PH and EC meters require calibration, and very frecuent to make things worse.
We have a professional lab PH/EC meter, actually used for beer brewing, but also used to help with day to day growing, and it's a pain in the ass to get calibrated every time before use.
I suggest using a solution with known values on both meters and see which one is the uncalibrated, hopefully it's advanced enough to be allowed to recalibrate. So good you have two of them!
Happy smokes!

Growth seems stunted?I feel like the growth is a bit stunted and she isn’t looking as good as usual. Leaves hanging/curling a bit down and some look a bit blistery (very lightly only). I just did a flush with 5.9ph water 25 degrees and the runout was 6.1 ph and 605 ppm and ec 1210 so I assume 1.2?

TDSI’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.

Is it worth buying mycorrhizae funghi at week 7?Is it worth buying mycorrhizae fungi for my roots at this point? I only found about this now and i’m planning on flipping my plant in about a week. I’m wondering if it’s worth the investment or if I might as well leave it on this plant. Do I need to take her out of the pot if soWeek 7
