I constantly found that I had to clean the strainers at the spray heads every few weeks. What I did was use two zone valves for each zone. Basically there are two seperate manafolds. One is fed from the the injector, the other manifold is fed from the water source. My beeds are 8 zones. After the 8 zones being fed by the injector run through their program, zones 9-16 run briefly with straight water to flush the lines and strainers. So basically zone 1 is fed by valve 1 & 9, zone 2 is fed by valves 2 & 10, etc.... Since I implemented the second manifold I do not see as much of a problem, the strainers last about the same as amount of time between cleanings as the non-injected zones.
If it was designed correctly you should not have stripes. Do you have matched precipitation rates? Are you using water soluable fert? Liquid will not give you problems like the water soluable.
Thanks for the semper fi wetboots!
