You shouldn't worry at all, the purple lines can appear even from slight stress on the plant. If you don't see any other symptoms, you should feel happy about your work! Good vibes! 👌

No, you can rest assured. It's either genetics or light stress.

issues late in flower
I am late in flower with my little blackberry kush and she has begun to fade. Shes foxtailing and doesn't seem to be putting on bud weight, has red stems and clawing leaves. Is this natural late in flower or something caused by me?
