need help identifying this strain

I have a plant that has now just entered the flowering stage. It is healthy and doing well, but since it was about 2-3 weeks it has had vertical purple lines on the main stem that go all the way up the plant. i believe that it is genetics because i got the plant as a clone from a fellow grower and he had the same happen to his. he called it number 9 thats all i know. Any help would be great.
Will post pictures tomorrow probably.
