ELOS Mg help

[Dyspnea]

I just got some ELOS test kits, MG, DKH, Ca. The CA and DHK worked well no problems. However I have done the Mg test several times now and I'm having issues.

I'm following the directions properly, I added 30 drops of reagent A, until I get the greenish color, I added the 5 drops of reagent B, the small scoop of the powered. And here is where things alway go wrong it seems the color of my solution is a very dark green/nearly black which according to the directions should start with pink and change to blue. I've added up to 24 drop of)reagent D and there has been no color changes (which seems like a lot)

Can anyone help me, I'm I missing something or doing anything wrong? ELOS Mg also seems to have the most steps in a Mg test i've ever seen.
