To me it looks like you are right and your nozzle is too far off from the print bed. 
The biggest help I found was printing the big wheels in the corners, the make adjustments of the bed a lot easier and more exact. Don’t be too lazy and make a couple of rounds until you adjusted the bed good enough, that you can move the head into every corner without he any further need to adjust. (That means you must touch every corner at least twice).

If you are already sure that your printed is absolutely level, the easiest fix would be to alter your printers z-offset via the M851 command:
1. Go to your terminal an enter M851 and the printer will reply the current z-offset, e.g. z-1.0
2. Next enter M851 Z-1.07 to lower your nozzle for the next print by 0.07mm (-=lower,+=higher)
3. Enter M500 to store the setting
4. Enter M502 to reload the new data from eeprom
