Auto #1 2700k for whole grow?

Hey guys this is my first grow
Il start off with my setup

Im about to grow the strain Auto #1 i ordered from the single seed centre
Im using DWC 5 gal bucketeer from stealth hydroponics, 2 clamp lights with dual sockets that have 2 40watt 2700k cfls each so its about 10000 lumens.

MY QUESTION IS: is it ok for me to use 2700k bulbs the WHOLE grow and still get a good yield?

To my understanding there is a very short veg time for auto strains and i dont really have the money to get 6500k bulbs jus to use them for a couple weeks

Thank you for the help
I appreciate any input

Anybody???????

Yes, you can use 2700k only throughout the entire grow. It is better to mix the spectrum, and you get out of the grow what you put in. You'll be growing this plant for over two months. It seems a pity not to spend a few extra bucks on more lighting.
