Leaves turning purple? Deficiency?

This is an auto purple devil on day 60 from germination.
Its had some dry spots and nute lock up and got a bit damaged but managed to pull through.
The flowers are beautiful and purple but the leaves should stay green, wondering if its defiency or anything that makes the leaves purple?

Ps: tried to look up reasons for leaves turning purple online but none looked quite like mine...

are the stems purple i can not see well.

Doesn't your plant have purple in its genetics?

Yeah, it's name lends itself to genetics. But I'd wait for one of the pros to chime in.

Yeah that down there isn't the purple you want. Looks like a defiency or something, maybe phosphorous, http://www.growweedeasy.com/phosphorus-deficiency-cannabis

Leaves towards the bottom like that usually die out anyway so it doesn't look that bad. And your getting towards the end at least.

Is this a new development or is this an effect from the previous problems? If you feel its from the previous problems just keep following your solution.

I only grow in water so can't really give the best advice on balancing your nutrition in your medium. My best guess would be to flush your medium, let it dry out, and reintroduce a medium level dose of nutes for its life stage. Kind of a reboot.

That purple is not good.
Looks like you overfed and locked something out.
