What is this Beautiful plant? how did they get it to look this way?

Hey i got this picture from ICMAG and i have never seen anything like this. this plant is gorgeous, but how did the leaves end up like that? The OP on the site i yoinked it from says its Sour Jack. but man that is a crazy good looking plant.

Id say afghan and It looks that way because its sucking up all the left over phosphorus from the leaves giving it the color shown.

oh... i see

That is a gorgeous plant. If we're going with the deficiency theory then I'd say lack of phosphorus and nitrogen.
However, I have heard of theories that say when a plant has a lower ph and grown at colder temps it grows purple and when at a higher ph and higher temps the plant will turn red. I'd ask the guy what the ph of his soil/water was and at water temps the room was at during lighting. That could explain the dark red fan leaves with a little yellow burn on the edges due to high temps. Just a guess though.

my guess is its a purple pheno that has some nute burn and was in colder temps...but looks great.

shiiit if it was mine,,,,, id brag
