Unanswered Plastic continually coming of the nozzel.

Okay so I have noticed that as of late when I start heating everything up I see plastic oozing from the nozzel. It's not like a blob or anything just a nice thin line continually coming out.

• I started my nozzel at 165C. I then tried to extrude 10mm, nothing. (ROBO 3D Glow PLA)
  
• 175C nothing
• 185C nothing
• 190C extrudes but then won't stop coming out. If I go lower it will miss spots printing.

Also during the bed level check; it leaves little spots of plastic on the bed. Is this normal for this to happen?
I have also noticed my nozzel appears to be to high off the bed. How do I fix this in Cura? Or how do I fix it manually?
