Thanks for the feedback and suggestions.
As far as copper goes, I think my IC probably takes care of that.
I have read in the Jamil Z/Chris White book about the relative slowness of first gen yeast. Maybe I'll harvest some of the yeast from the current batch and make another CAP just to see what impact that might have.
Also, from the Jamil Z/Chris W book on yeast, I did figure out that I might have under pitched by 20% from the recommended level.
I guess the take away for me is more/better yeast and some additional nutrients.
