Should be fine adjusting after mixing, but I don't have a ph pen so don't use that method of ph control. I use the color-coded ph test kits which don't work once you add a colored liquid. (nutes)
I also use knowledge of what nute lock-out looks like in my plants, coupled with mag sulphate and flushes when needed.
