This NorthStar Broadcast Nozzle does not have an adjustment. It is only adjustable by the height and angle. This nozzle does require a minimal of 1 gpm at 15 psi.

I get a 12 foot wide spray with the nozzle set at 3 feet above ground level attached to a tow-behind sprayer that has a NorthStar 2.2 gallon per minute pump.
I filled my tank with water and did a test pass on dry concrete. I got full saturation 12 feet wide and saw no gaps in coverage.
I used the unit to spray a total-vegetation killer in a pasture and the results were clearly successful. There were no gaps or patches of vegetation that were not dead.
You might want to fill your tank with water, remove the hose right at the nozzle and verify you are getting the volume and pressure you expect right there at the nozzle end of the hose. Mine initially was quite low and I found a fouled in-line screen-type filter at the pump input connection and some thick gunk in my hose lines themselves. Once those were cleaned out I got the results noted above which are quite satisfactory for my purposes.
