Sounds like some of the chemicals are not going into solution. This is odd because I have not previously heard of this problem and have never experienced it myself. I would recommend as a general precaution that when adding the chemicals you make sure that each goes completely into solution before adding the next. However, the only really stubborn one is phenidone and since you are already mixing it with alcohol before adding it to the solution I am really stumped as to why some of the chemicals appear to be settling out of solution.
