it looks more dark green than purp probably had an nitrogen toxicity at the end of flowering.. tastes quite trashy, but will do the job.
High salts are a great way to cause purpling (i.e lots of ph up towards the end of a hydroponic grow).. While much of the color can be lost to curing, I'd probably chalk it up to that before I'd go for N toxicity..
