Yes i use something similar for foilage spraY and soaking my rockwool. If that's whatyour talking about. Is it basically B1 or sea kelp?
Its also good for transplant shock i looked it up its basically the same thing i use just different company.. why do you ask?
that's not a bad idea bro I use it myself. just make sure you don't overdo it. also depending on what kind of soil you are using you are going to need more than just the super thrive expecially when you switch to 12 12
