This Chinese cabbage leaves is changed to yellow color on the edge of leaves.
My teacher said me.
it is caused by strong pesticide.
But it's not so problem, he said.
Because those plant are still small, young.
So they can cure it. You can see new green leaves the center of Chinese cabbage
And if you spray strong pesticide when plants are young, the leaves
become stronger against insect and disease.
But it's not non-problem. So you should spray early morning or late evening.
Because in that time, there is moist on leaves. So leaves are hard to be
burned by pesticide.
