titterbug,
I put down a link below that I had bookmarked. Since you're in Canada is this a greenhouse grown plant? I know you said stems (plural) but is there only one plant of one variety with this condition? Anyway, there should be some help by comparing the pictures on the link. |
Here is a link that might be useful: http://aggie-horticulture.tamu.edu/tomatoproblemsolver/index.html
