It is slight pitting and it has the toner that I didn't wash off properly. I'm not using any agitation other than swirling the PCB around in a plastic dish. The Direct Inkjet PCB guys noticed that Ferric Chloride is more forgiving for resist than acid etching as well. The Hydrochloric Acid is cheaper and nicely see through, like Ammonium Persulphate so it's hard to get rid of just because of the rash that I get on the board. I still have FC here for those times that I want a pretty etch.
