Are My Stems Supposed to Look Purple?

I know purple is usually a sign that something is wrong. My plant looks health to my knowledge. I am growing Ultimate Purple in a 3x3 running ocean forrest soil. I ph my water (6.2-6.8) and my temps have been 78*F Humidity 55%. I was running a 300w vivosun LED on full spectrum, however I just switch to a 600w vivosun LED today/.I also noticed it doesn't look as purple with the lights off. Am I being paranoid.
