WEEK 10 Flowering!! 45% ORANGE HAIRS?

I have a question...I am on week 10 in flowering with my White russian's. My plants only have about 45% red hairs. I am getting anxious and want to harvest them. If I start 48 hours of darkness now, will there be a significant increase of orange hairs after the two days?

Not really. Give it another week or two. Harvest a single branch if you're that hard up.
