Looking good bambam....Thanks for the update. Something to start training your eye to is plant color. When conditions are right then your plants will be a DEEEP green. Plants that have a very light green color or geenish yellow....or if you're seeing any reds and purples....then these are signs of nutrient deficiencies or stress.
Lighting can make a big difference in a picture but from what I;m seeing your field still has a greenish-yellow look to it. My guess is its needing some nitrogen but it would be good to send in a soil sample just to see how everything else looks like.... P,K, pH......Go ahead and add your other bag of 13-13-13 next trip. It would be good if you had a little 33-0-0 as well to put out but its no big deal if you don't.
