Depends on a lot of things, it could be:

The phenos of those plants
Fan or heater pointing at them
hydrophobic substances in the soil like the powder from perlite
Where the out take fan is
where the intake fan is

If there aren't any fans or heaters near them then its probably just the phenos. I water all my plants individually when i think each of them needs it so maybe try that to prevent over watering.
Hope I helped
