DIED, I'd recommend that you take a pH reading at around 8 p.m., and then around 6 a.m.
pH fluctuates so much during the day, depending on whether your plants are photosynthesizing, or respiring.
The pH graph is meaningless unless you are getting readings at the same time of day each time.
...or did you know this already and I just missed a previous post? The picture you included in your 1,000th post has distracted me from the true meaning of this thread.
:p
