Update, 5 other folks reported similar results in terms of pearling rates, and growth rates/water clarity.
They only changed(to the best of their knowledge) the delivery without changing the rate of CO2.
Dramatic changes.
PO4 was not this intense.
If you have grown plants a while, you know when you see good growth(even if you cannot measure it with a meter/Test kit etc).
I've suggested several plausible reasons for the observations and the DO meters readings as well as the visual and plant observations also correlate well.
My red plants are no longer red, they are all silver from pearling.
