Too much Barricadce will keep the pH on the rise.
It is best to use just enough Barricade or silica blast
to bring the pH up to minimum
and then it should stabilize.
I always use an eyedropper when adding Barricade/silica blast.
Just a small amount is all that is needed.
Also some calmag will lengthen the stability time.
I try not to go over 100ppm calmag
and 50-70ppm is probly better
depending on your nute load.
I am using botanicare calmag-plus
and it does not change the pH but it will stablilze it.
About the time you get the pH really locked in,
it is time to flush and start over.
After a few tries
you can get ahead of it,
and get the pH stable for 3-4 days.
My pH drifts from 5.3 up to 5.8
in my 20gl aero system
in about 3 days.
I use about 1ml Barricade for the 20 gl
.
