barley yellow tips

[suffeks]

today I noticed certain spots in the field look like this. I'm guessing lower pH patches. new growth looks healthy, its just the old leaves.

so nutrient deficiency? maybe I can apply something foliar tomorrow... my other thought is glean phytotoxicity. i applied only 15g/ha. i would say its too early in the season for bugs or diseases.

oddly the low spots of the field are fine. it did rain alot though, maybe lack of N?

One of the more mobile nutrients going short!
Oldest leaf tip going that colour means nutrients moving/transfering to the newest growth/youngest leaf, which looks a good colour!

ok ive concluded its chlortoluron injury, this hyvido must be sensitive, probably will grow out of it. i have a spot in the field which i did not spray and its twice as big and twice as green without any yellow tips.
