The white lighting can be deceiving , appearing hungry. Not saying they couldn't use a feed, 1/4 dose.
I see curling of the serrated edges, are those fans blowing directly on them?
16° is very low. Have you considered running 24/7 to keep temps stable? Also, a fan controller for exhaust would help keep heat in. You can get one for like $20.
Being that cold, I don't think they are drinking as much as you're watering. How are you testing the need for water? When the top soil drys, it's still wet in the rootzone.
Can you take pics outside of the tent to see the real color?
