    Some areas of my Jap Millet got over planted. All of the areas, which are to thick, are more yellow and leaves tips are a red/rusty color. All the areas that were planted at the correct rate are green, twice the height, and look good. Have had a few showers, so not competing for moisture. Any thoughts?

    Looks like a nutrient deficiency. Possibly nitrogen and phosphorus? I'd take a sample by the local extension office and let the county agent take a look. While I was there I would also pick up some soil sample boxes. Get separate samples from the affected areas vs the unaffected areas for a comparrison. If not a soil issue, possibly a drift issue. I don't know how secluded your place is, but dicamba drift has been a major issue in Arkansas this year. I doubt that's the issue though, cause it's not wide spread across the entire plot.

    I would dump 100#/acre of DAP or 20-20-20 on it. That should address the N & P deficiency symptoms. If you wait for foliar or soil test results, it's likely to be too late to matter.

    Yep, broadcast the 100 lbs/ac. of 20-20-20 or something close to it. I wouldn't wait for tests either.

    And what if he has a ph issue or it doesn't rain for the next 2 weeks(it is August afterall)? Just spitting into the wind. Any reputable university soil lab should be able to get you results within a week this time of year. Regardless of what you do, get a soil sample. Might help address this for the future if not this year.
