Hi Veggies To Go,
I'm not sure I understand what it is that you saw.* Did you happen to take a picture?* This corn diagnostic guide is one of the best I've come across.* Unfortunately it doesn't have pics, but you can look up the symptoms on google and click on 'Images' and you might get pics.* Do look at the stage of 'Tasseling to Maturity'.

Let me know if you find anything that sounds like what you saw.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
