Flower discoloration

Looks like she is just a purple pheno to me.

Looking up information on this particular strain, I've found it DOES lend itself to a range of colors when in flower... so to ME, this looks absolutely normal and I think you're going to have a wonderfully colorful harvest! "Appearance: One word: beautiful. The NYC Diesel is characterized by flamboyant buds with splashes of blue, purple, and yellow. The flowers have an inviting olive green color, with a sheet of crystal trichomes and amber pistils that will get your fingers pleasantly sticky." https://green-theory.com/nyc-diesel-strain-review/ Good luck and enjoy!!

Im actually worried this is an issue and of concern. I’ve had this color show up outdoor on certain buds and it looks just like this, keep us posted cuz the way it’s showing is a bit off for normal color but I could be wrong .

That's just genetics, my friend. Enjoy the views from now until you harvest, there should be lots of colors.
