Not a fantastic picture, at least from Aurora,CO USA looks like genetics..

How many days in flower, what lineage, current temp outside, nutrients, pH. Details my friend! Details.

Could be genetics driven but it's probably holding on to a lot of N. I agree, looks otherwise very healthy. How is it smelling?

Yeah, I would say genetics! But if you’re in Australia, you were probably growing it in some pretty cold weather! Just now coming into spring! That might have something to do with it! It’s pretty!

Yup, probably the cold. My GDP in the cold

Thats just genetics, if it has N toxicity its barely any. No clawed leaves. Looking beatiful
Im expecting my dos-si-dos to throw some nice blue aswell since the temperatures go a little bit below 19ºC with the lights off and it has blue genetics.
Black is just a lot of blue or purple, makes them look black sometimes but its not really black.

slight N tox upper level of leaves with slight clawing but nothing bad, shes good, the color, thats genetics, if they go evenly purple though mid to late flower, my Gary Payton x okie got so dark she looked black, but purples, pinks, oranges, all come out depending on what genetics shes holding

heres an apple fritter for example

I had a plant last year that threw a blue hue for a day, in August. Only lasted till next morning, then back to normal.

I've come across some conversations that suggest pH affects the colors the anthocyanins will show, with a lower value appearing more red and purple and higher pH taking on more blue. I had a run of a pheno I've been keeping turn out a little more "teal" color than I've had in the past and with that run I was struggling with buffers that had run out and was sitting low 7's when it was done so I believe there's something to it.

Years ago, when I was growing in my closet, I found that dropping the temperature to about 16 °C with an air-conditioner could bring out purple tones in the plants. It didn’t have to be freezing, but the strain did need to have purple genetics.
