looks like a trace mineral deficiency starting up... what are you growing in?
PH fluctuations most likely. Not bad really. I wouldn't worry too much.

water more carefully at exactly 6.50 pH. We suspect that your pH is out of the usable range of 6.3-6.8. Since you are coming in on the low end, this almost definitely points to a molybdenum deficiency.
Nice chart Emilya. Saved for print and laminating.
