I made two PCB's around December, and have recently been planning some new ones to make. I went to etch them, and on two separate occasions each with new Ferric Chloride mixture (of the correct measurements), a discolourment will occur and the PCB will turn a tint black, then after a while it sometime hours turns green, or drys to a dark brown. What is going wrong??? i made two PCB's a few months ago with the same HP photo Paper, and the same ratio on the Mixture. Also I have used the same iron, attempted to keep the temperature the same and it still wont work??

please help I am wasting materials and i don't know why!!!
By the way, discolourment usually appears within the first 10 minutes, both pictures are after 40 min - 80 min in Ferric Chloride around 20 deg
