Yeah this is pretty common for their purple strains to get some mutated growth but they end up with great buds. It is hard to tell if any issue is going on with the color from the light, but I would check the pH of your runoff just to be safe. As long as the pH is between 6 and 7 then you are good there. And give her a light dose of grow nutrients high in nitrogen and a little calmag if you aren't feeding her something already. It looks like there might be a slight lightening of color in between the veins which would be mag deficiency, but could just be the lighting? I would also try to get the humidity up around 60 and that will make her happier. Good luck!
