Corn comes out of the ground & kinda sits there for a while, waiting for hot humid weather to really spurt, the growing point takes off and shoots up in just a few days.... That waiting period it develops a root system, gets ready to grab moisture & fert & grow like crazy.

Anything that slows the corn down will be _very_ noticable about this time of year.

Compaction.
Lack of N.
Too wet.
Insects.
Poor soil.
Too dry.
Seed depth/ spacing.
Shading from weeds.

You need to walk your 'field' and figure out why one plant had a great growth spurt, and the ones a couple feet over did not.

In 3 weeks, the effects will be less noticable, as the corn that had 'issues' will grow out of it & all the corn slows down to concentrate on setting stalk strength & ears & tassels & not so much on growing upward. However, those plants did lose 10-40 bu an acre as they had to play catch-up to the rest of the field.

You are looking at the corn at it's break-away racing phase, and for some reason some of the plants missed the green flag start. You need to figure out why if yield is important to you.

_Just_ adding fert might not help, until you know the real problem causing this.
