I spray-tested my lawn today using Q4 to test it on crabgrass/nutsedge. I was using a Hudson never pump backpack and Teejet AI11004 for the first time (per Greendoc's suggestion) for low drift. My issue was that the water filled droplet's landed on the crabgrass/clover/dandelion and didn't "spread" out, they simply landed in the bead form it came out of from the sprayer. I added probably .5 oz De Fac surfactant to 3 gallons of my mix. Was that not enough? Is De Fac even any good? It says non-ionic surfactant. I used about 2.5 oz/gal Q4 since it was a little warm today and it was being put on a terrible mix of bermuda and fescue. I am used to spraying Glyphosate and seeing the pretty "glossying" of the leaf blade due to the sticker it comes with, and the sticker I add. Why did the Teejet make such bubbles? Was it enough for the weed to soak up?
