I'm not sure if these leaves have some sort of disease or if it is a nutrient deficiency or maybe to much of something. Anyone have any ideas? Thanks

The first thing I would do is give it some high N fertilizer and see if they green up.
It might also be from water stress.
Keep it watered good.
It could be an early sign of disease but I don't think so.

Here's a good link for pictures to compare. Without knowing what you've done or not done its hard to recomend anything.

Has your area been hit with 30 days of rain like in some parts of the US.

I had two plants do that to me Mark at a time when soil was saturated, nothing but cloudy skies, and at the same time and location on the plants. The plants came out of it and growth returned to normal, although the affected areas will be stunted. It couldn't have come at a more inopportune time either, as it also affected the females I had tagged for pollinating. Growth from there on out has returned to normal and I'll get the next females on those two plants. Don't do anything drastically reactive. It's a weather-related condition.

Adding N now in response will do no good, as N cannot be taken up until things dry out a bit. By then, you'll be faced with too much of it at a crtical juncture in the season.

Right, If the roots are being suffocated N will not be absorbed very well.

Looks to me like Manganese deficiency. This is common in AG's at or close to pollination time. Symptoms are light green leaves with dark green veins...it apears on new tissue first....apply a couple apps of filiar manganese, two weeks apart....this condition will show up when there is a soil deficiency and then the plant is subjected to stress...I.e. Rapid growth phase, combined with high heat/ drought conditions.

Hope this is helpful

The Manganese deficiency theory fits. It definitely occurred during high heat/drought conditions. Although those effected areas did stunt the rest of the plant is now growing beautifully!
