Could some one have a look at my grower diary for July 5th. About ten % of my leaves look like this. Haven't used any herbicides or pesticides and no round up or 24d around patch.Plant looks healthy besides this!!!

What are you using for fertilizer? What did your soil test look like? This is leaf tip burn...I don't have my book right now but can be caused by a couple things.

The white spots are cal-carb that I applied the night before. Sunburned leaves usually show up as a crinckly leaf that eventually turns brown then falls off. These leaves aren't following that pattern. I am only using 10-10-10 at a very low rate. Cow compost was put on in the spring!!
