Would anyone have any idea why two of my strawberry plants should have dark purple veins on their leaves...? Should I be worried...?

It couldl possibly be a virus brought by aphids. Inspect the leaves carefully, as well as the stalk and stems and see if you have any aphid buildup. If you do, spray for aphids if ladybugs aren't about and pull and bin the infected leaves.
