Lawn looks very nice. Super deep green. The primo maxx in my use of it does exactly what its supposed to do. You may need to experiment with application rates and time between applications at first. Varies with time of year as well.
A good sprayer is a definite must. In one of my first uses i missed a strip around 3cm wide between spray passes and for 6 weeks it was always around 10-20mm higher before mowing
I got mine last year from here
