Go for it man. I believe those are made for use with any nute line up. I’m not sure exactly what you mean by phase ratio? I would read directions on front, use low end of recommendation. I’d only use one of these tho, I believe it’s a bit redundant using both but I could be wrong I’ve never used either.
I can literally read on the front from zooming in it says compatible with any fertilizer in bold print. It also says 5-15 mil per gallon in flower.
I believe they are similar like I said, and I’d only choose one if I were you. Then again, I don’t believe the purpinator will actually do anything significant to bring out color.
