It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

Be careful if you use Ni/Au. The "black pad" phenomenum can be crippling. We moved from Ni/Au to OSP because of it. I also don't want to return to the lack of flatness of HASL.
