slow growth and leaves cupping down

Soil is mg seedling soil, ph of water is 6.8, temp of room is 73ish, plant is maybe 2 weeks old with four leaves and about 2.5 inches tall. lights are on 24/7 which are 2 four foot Fls 1 daylight 1 growlux, and 3 cfl's 14 watt which are daylight also. I water when soil is dry on the top with a spray bottle. From what I noticed this soil really sucks the water up. I will transplant soon to fox farm but I would like it to get a little bigger. Lights are a inch or two from the plant.

so i need some nutes from what i have been reading from the above link, it does have a reddish stem also, but its so earily too add nutes with mg seedling soil right?

Some plants just have reddish stems. Adding neuts will not help.
PIC please. That will be easier.

sorry no camara but from reading I think it's because of low hudmity. it's very dry in my house and i'm using a space heater in closet to keep things warm. which drys things out... right???

I just plugged in a humidfyer now.. just a cheap one i had lying around.
