Help??

So I've been doing this for about 5 years or so and never seen anything like it. She's into her second week of flower, fed 1st bloom nutes yesterday and today she's got these strange stripes right down the center of the newest growth. Any ideas? She's a purple kush so I'm hoping it's just a random genetic thing

Think I seen something like maybe virus

I really don't have a clue but I seen a post that people were putting on here that saying that had a problem looking something for viruses buddy
