Well calibration and angle. I'm treating it as one nozzle. I want uniform coverage on the plant and row. I feel like the first row is good but the second and third get overspray. If I pivot volute up I feel I don't cover well. I'm spraying strawberries, 1 acre, planted on 5' centers. The info from manufacture is not super clear, they say it's an art not a science. I'm not very artistic. I plan is to use nozzles that do not apply as much, and travel slower and focus on one row at a time. Pretty much shooting straight down. I would like to spray slower to give fan time to really swirl foliage more. I'm I on the right track?
