I took 3 samples of Happy Frog and did a 24-hour slurry test. I was curious since we get so many questions and see so many issues of newer growers having problems with this early in their grow.
I thought it might be useful to post results with these key words so it shows up in folks’ search results.
Here’s what I found (variances are approximate):
PPM: 850, +/- 75 PPM
pH: 6.6, +/- 0.3
