>>I use two wide carriage printers, HP 1050cPlus, 750cPlus. Neither's colors matched my screen, I use photoshop cs6. I calibrated my screen with a Huey Pro, and created a icc profile for the 1050 using a Spyder3. I do a soft proof in ps and see some green blotches in shadows and other places. I print on kirkland glossy paper (same as the test prints) and get the same green blotches. Some of the skin tones are off too. I'm printing two pages of test prints, a total of 240 patches. I print using the printers color profile and it is actually better than using the icc I created with my Spyder 3.

Okay, I'm going to assume from this that you calibrate your display(s) with a Huey (not ideal, but better than being uncalibrated). And that you use Spyder3Print (patch reader) or Spyder3PrintSR (strip reader) for profiling printer/ink/paper combinations. 

>>Most of the photo came out good, just some colors were bad. I read somewhere, that I might try printing new test prints but do 720 patches instead, or whatever the number is.

Increasing the effort and materials used before solving your problem is not a good idea. While your description (blotches) is new to me, and not very technical, if you are getting areas that are very off in color, that is most likely indicating errors in the patch or strip reading process. 

Open your existing measurement set and toggle between the "1" and "3" keys to see the values sent to the printer, then the values produced by the printer. Make sure the shift from the ideal to the real is even and consistent, and that the gradients are smooth, without any big, unexplained jumps. Reread any areas (you did save the printed target sheets, didn't you?) that are suspect, and build a new version of your profile. See if it prints differently than before. If so, there were errors in your patch reading previously. 

If that does not solve your issue, then it may be a color workflow error in the settings used. The best way to solve such issues is a support ticket at datacolor.com, not though forum discussions, but I thought I'd give it one shot, before sending you to the support system. They will want a copy of your measurement set (not just the profile), the details about your OS, printer, inks, and driver, as well as the settings used when printing targets, as well as prints, and a detailed description f your results, using the test image in the Print software, so gather as much of that up as possible before contacting them, to save time on both ends.
