I don't see why not. I mix my trace so others can dose it when I'm gone.
I dose a CSM+B plus Fe solution almost daily. (do forget from time to time)
500ml bottle (I double everything but the Glut for the 1000ml bottles)
14.4g CSM+B
35g GLA Fe 11% DPTA
30ml Excel (actually 1.5% Glut)
Mixing a new bottle of soup it takes about two days for everything to stay in solution.
I shake the bottle a couple of times a day and turn it upside down to see if anything settles.
Currently doing about 5ml/20g per day.
Millers is very close to CSM+B isn't it? or I missed something
Dry in the jars I noticed my trace tends to separate into layers just sitting on the shelf.
