Black Leaf Edges on my Purple Haze

[snappybob]

I am growing these out in my green house. I am growing about 12 varieties. This plant was sown about 6 weeks ago. All of the other varieties look OK. It's just the Puple Haze. I am selling tomato plants but I have pulled this variety due to this leaf problem. Is this some kind of deficiencey that will go away once the plants are in the ground or a disease. Any help would be appreciated. Thanks

Reminds me of what I had in the greenhouse Carolyn called CRUD. It happened only on some varieties, and went away when they were planted out. Not sure exactly what it is, but it was harmless for me.

Thanks, I sold two in the last hour. I pointed out the leaf problems and offered to substitute another variety but they didn't seem to be bothered by it. They bought them anyway.
