Leaves turning purple

[Kpenn]

This plant has been butchered and tortured and somehow managed to stay alive this long. It's OG kush and been in flower for about 14 weeks (10weeks average) I'm figuring I've put it through so much stress that it's just stunted her growth that's why she's taking so long to finish up. She was part of my first grow with the manifold technique so she's been experimented with. But here's the purpleing of the leaves and onto the stems. Looked it up on the website it said possible phosphorus deficiency. What do you guys think??

The purpleinng itself is not a red flag. But the way the leaves are droopy and curled. Very weak and small buds. What kind of light are you using?

CFLs it was one of the plants in my first grow, it's kinda been my experiment plant. I plan on just letting it finish up and using it all for bubble hash.

the cold can make them go purple sometimes or its just genetic, no worries in my book it looks frosty enough for bubble hash
