First of all, I get a brown solution when I mix up Selectol Soft also, I
think that's relatively normal.

Secondly, dividing the chemicals up the way you did is inviting problems.
There is no assurance that the various powders are uniformly dispersed
through the mixture. As a result, there is no way to assure that each
batch will be identical. Even though it is more expensive initially,
you'll end up saving by buying smaller packages because you can depend
on consistant results.
