I'm thinking it has something to do with organically or synthetics??I running Botanicare PBP w/supplements. On Botanicares site I've found where it says to add silica first, then in another area where it says to add it last.
Under the Silica Blast FAQS:
"Q: When mixing nutrients, should I add Silica Blast before or after adding other supplements?
A: Silica Blast should be the last product added to the nutrient solution, before adjusting pH. Silica Blast tends to increase the pH of the nutrient solution significantly so it is best added last, after all other nutrients have been mixed in."
On the PBP feed chart:
"2. Follow these steps when using Silica Blast or Cal-Mag. When using Silica Blast, always add Silica Blast into your reservoir FIRST followed by Cal-Mag. If Silica Blast
is not being used and Cal-Mag is, Cal-Mag should be added FIRST, then add the remaining nutrients"
I've always wonder d too because there is such differing opinions.
They're probably both right depending on the product
I always hear "use it as ph up" but if it had to be put first thag wouldn't add up
FWIW I try to figure out how much SIlica I need to get my ph right and add it to my res first. But if it needs to raise I add more after everything's mixed.
I haven't seen any evidence either way of it not mixing. The Ph always holds steady after raising it so I imagined it mixed well
