whats going on with my blaster?

I'll try to keep this accurate,I just got medium grit glass media and it doesn't appear to be firing right.
It doesn't seem to be coming out of the nozzle just a lot of moisture. I empty the tank after each use. To confirm my suspicions I
made a mark on a stummel with a sharpie and tried to blast it off it did not come off . The million$$ question is whats the problem?
Pick up tube clogged? gun build up ? your thoughts will be appreciated thanx

Do you have a water trap in your line? Sounds like you got moisture from the compressor in your media and it's clogged the syphon hose.
