Cold temp at lights off

when the lights come on, i'm of course waiting at the door like some kind of stalker lol.
the temp in the room has been down to 14.5c, the high has been 22.5 - 23c.

Just wondering how cold can they take it? they're all between 3 - 6 weeks. What's the minimum safe temp?

They will stand a lot of temperature extremes. 10 C at night will start slowing growth. If you are growing coloured plants they should end up really pretty with those night temperatures.
