Typically yes, the solution turns green within a minute or so
No discoloration at all, no residue. Solution turned light blue/green. After the first attempt there were small amounts between some of the traces, and a larger area just off the board, on the excess margin (I file it down to make it pretty after etching lol). After second attempt, the copper inside the traces was gone, but the larger area seemed unaffected.

The etchant that you say failed to remove all the copper from the board, what did it look like? Was there a bunch of brownish solid floating around in it?
Your new batch, did it turn green when you performed the etch?
I stand watching the steam-liners roll by...
