Blueberry leaves turning orange
Have otherwise healthy, large blueberry plants. Lots of blueberries on them. Within last few weeks, leaves on some plants turning bright orange. Have I been watering too much? or any ideas? Thanks! Allen Neuringer

Thank you for your question, Allen. Are you able to take a photo and send back? Since we can't tell from your description whether this is isolated, or throughout the leaf, it's hard to narrow down potential issues. Thanks for more information!
Pictures are of the 2 plants showing this "disease." They lie at the bottom (of 15 plants) of a hill and may have gotten (I'm guessing) too much water. 3 Images attached. Even on the affected two plants, it is only a part of the plant that seems to have the problem. Thank you.
Thanks, Allen. I’d like you to take a look at the photos in the following Extension article: https://blogs.cornell.edu/berrytool/blueberries/leaves-are-unusually-colored-spotted-or-necrotic-browning/ I think your plants have iron, potassium and possibly nitrogen deficiencies. Have you had your soil tested? A &L Agrucultural Labs near you can do the testing and make amendment recommendations. It’s probably not too late (although you may not get any/more berries this year). Here is contact info for A &L: http://www.al-labs-west.com Hope they can help. Good luck!
