purple leaves 30 days into veg?

I water once every 3-4 days or till the soil is dry
Lights:2x 110 Watt LED's 20 inches from the plant's surface
Using a fan that's blowing above the lights, not direct.
Temperature is around 74-79
Soil is bio-bizz all mix
Fed them 3 times with Bio-bizz Bio-grow and some Bio-bizz calmag.
Plant is 30 days old. Topped it 5 days ago.
Pot size: 0.9 Gallon
Humidity is between 55-65%
water pH 7.0 (adjusted to 6.5)
Seeds is 24K Gold from DNA genetics

Thanks for your time

Probably time to start feeding more often, if not every feed.
