It looks really good overall. Beyond that, are you getting a good positive roi to all those inputs? If you want to improve more, you need to be able to better measure things.

Soil moisture sensors are invaluable to me for any crop. What you see above ground is a direct result of what happens below ground. Usually all or parts of irrigated fields get over irrigated early because guys don't want to run dry. Hard to manage without a good moisture sensor.

I'm not seeing obvious nutrient deficiency of any kind from those pics. Your ph is high and that makes nutrient availability harder..
K is very cec dependent.

I think you need to better finish the crop out. Maybe not more nutrients, but at least keep applying later in season. Lots of nutrient uptake long after 10 days after tassel. Like 40% of N (although you don't appear n deficient). Do some in field tests fertilizing some acres later and see if you get a response.
