How much armor si to use in deep water culture hydroponics ? Was using like 50ppm at first and then 150 ppm calimagic b4 base nutrients. But my ph went high and had to add a bunch of ph down. When I mix my nutrients without armor si my ph usually don't need to be adjusted unless it drifts up the next day or few which then I drop it with ph down. Seems like a waste of ph down adding this stuff. Any thoughts or opinions?
