Artichoke experts

[catjac1975]

I have had great luck with starting artichokes the last few years. I grow them as an annual and they have produced nicely for growing up north. I have some lush seedlings in the greenhouse. But, they have some leaf discoloration and a few dried leaves. Other than that the plants look wonderful. I am thinking they may need some trace mineral or something. I think I remember reading that tropical plants need copper once in a while though I have never used it. Any of you experts have any thought?
