Phosphorus deficiency?

[Yaggi]

This plant is about ready to harvest, but in the last week it's shown some autumn color. Not sure if it's a problem so late in the game or not, thoughts? The temps have been cold here at night, 50 or below almost every night. Basically i'm wondering if this is gonna be a problem when I chop her down, or will this just enhance the color of my ganj?

I think if you'll get harvest soon the color is not important.

Yeah that's what I was thinkin, I guess i'm more concerned if this is just normal color change? or if this can effect the final product in any way besides color. I'd love to see some purple in the final product and if waiting another day means that, I might just do it. If it could potentially harm the plant to leave it in the ground any longer, then she's comin down ASAP.
