Well, with some woods any oil finish will cause blotch and some are a lot worse than others. What is the wood, and is it possible to get a pic of the effect?

I just bought that Earlex 6000. Do you think it’s the mix, or the varnish? I’ll be interested to hear the final results on this topic.

It might be blotchy but I can’t see through the orange peel and dry spray to the surface.

Sand it back and apply a thinner coat. It should be wet, but not puddle. Do you have an exhaust fan?

Like OSU55, I can see orange peel, but not blotch. Is it possible you are calling the orange peel (un-smooth finish) blotching?

Ok whatever it is orange peel, blotchy whatever. I just want a smooth finish. I need to sand it down and apply a thinner coat. I do have a fan blowing out.

I assume that’s a test piece, not the final project that you are spraying on. Like Fred and OSU55 said, that’s orange peel, not blotch. Generally, orange peel comes from finish that is too thick. Take Clammy’s advice and thin out the finish a bit.

There are videos out there that might help you get started, but I found that practice is what will get you there. Variables such as the species and surface prep of the wood, the finish you’re spraying, temperature and humidity all affect the finish, and no one setup will work for every situation.

Be sure to be practicing on sample boards of the same type of wood and surface preparation as your final project. Sand to the same grit, seal coat, stain, whatever should be the same, since oils in the stain can affect how some topcoats behave. Take copious notes too. For HVLP systems, adjusting the air and fluid flow rates change how the finish will behave as well.

-- No matter how much you push the envelope, it'll still be stationery.

Like RichTaylor said practice boards of the same material are a must. Looks to me like a bad air/fluid/thickness issue. First spray just plain water on cardboard to get close to the mix, then spray the cardboard with your finish, then some practice boards that are prefinished with whatever your project is done with. (stain, oil etc) You can just wipe off the practice boards with a rag and try again before it drys. Not to worry. I think we’ve all had similar issues. If that is your actual project just sand it off and start over.
