6 days old Northern lights AF, YELLOWISH LEAVES.

[Felix.jude]

Hello everybody,
This is my first grow. The strain used here is Northern Lights Auto flower from Nirvana.
It was planted on - 8/8/16
It's under a 45 W 6500 k cool light CFL. I've been keeping the lights on 24 hrs. Watering little amounts every 24 hrs.
I am using 100% organic potting soil, with exceptional drainage.

The YELLOWISH center towards the end if the leaves started appearing about 3 days in. I am confused if it's natural and to the strain or if it's a deficiency.
I am also growing a male sativa with it which appears to be doing fine and is healthy.
Thanks a lot for your time and help..
Any suggestions are appreciated.
