Is the latest package you opened from the same carton as the previous package?
If so, it is the same fluxed chemistry.
It would appear that your Ca and Mg levels are low. This could be a result of low specific gravity / salinity. Recheck at an honest SG of 1.025-1.026 / 35 ppt.
If the solution from the latest package test differently than the previous package from the same carton, consider some variable in testing procedure and/or a change in reagent test solutions.
