You sprayed once, then twice, and the weeds are still standing. The herbicide didn't fail you, your water did. When your spray water sits at a high pH, the calcium in it wraps around the herbicide molecule before it ever reaches the plant. You mixed expensive water and called it a day.
We get into two things here. First is gypsum, what it actually does to your soil, why high magnesium locks your ground up tight as concrete, and why your soil test can show plenty of calcium and still have none available for your crop.
Second is spray water pH, how to test it, how to lower it, and why a coffee can of citric acid in a thousand gallon tank can save you an entire extra pass across the field.
There's a live demo in here too. Watch the pH drop in real time with barely a pinch of citric acid. Once you see it you'll never skip the water test again.
