Anyone running water soluable packets out of their Magnum?? This is the first year I'm doing (2) different things. 1) I bought a Magnum, sold my Ultra, so I AM used to running a ride on. 2) I switched from 19-0-7 .15% granular Dimension to 10-0-20 Fert + Lifeguard (Dimension) water soluable packets, to try to stop the excessive top growth in my KY Bluegrass that I have to maintain mowing as well as chemical apps. My problem is, is that I cannot keep the nozzles clear. I go 5', and they're plugged again. Pull everything apart, clean the screens, put it all back together, go 5', they're plugged again. I was wondering (hoping) that someone else has run WSP's through their Magnum yet to tell me for sure that it can be done, especially LifeGuard?? I've been mixing it in a 2 gallon bucket first with water, then putting it in the Magnum. Then adding the rest of the water.
