Could be temp to low.

You're probably fine. I always have plants with reddish/purplish tints to the stems and leave veins. I've never had a problem with it. Just give them some time. How's your watering/feeding schedule? Nutes?

Watering when the soil is dry.
Its in a 6 litre pot and I water it about 2 litres at a time.
Enough that a small bit drains out the bottom.
Overall the plant seems healthy.
It's in a cardboard box. The temp, because of CFL bulbs, is between 80 and 110.
Its 100-110+ just above the lights (heat rises)
Not sure what the temp is at canopy.
Humidity has been between 50 and 75
If my hygrometer is accurate.
I figured it was just genetics. Googling suggested magnesium deficiencies.

Canopy Should be 75-85, from what I read.
The cfl keep the ambient temp above the bulbs to about 90-100 with the box door open. With it closed more the temp is around 100-110
But it's noticably cooler below the bulbs than above it.
I don't have a way to get a lower temp reading with the thermometer I'm using. It's from my reptile tank and it's just taped to the lights wiring.. :/
I believe the plant temp is fine though. It doesn't have many signs of heat stress.
When I first added more bulbs I didn't realize the temp would spike. so after a few hours of the plant roasting, I noticed twisting leaves and corrected the problem.
It's been good since.

Usually one of 3 things for me, Genetics is 1 main factor based upon stain, next is Neuts, usually cause I put more than I should, 3rd Water based upon temp and ph which as others have stated may lead to stress which in turns leads to stunt growth.

Shittake, peep Amazon for a laser thermometer. You can shoot it right at your canopy and read how hot a leaf is. I got mine off there for $15. Love the thing.
