to me she looks very thirsty, plants that size need 5l daily at least if not more
so give her daily water,
first time let her soak wet complete
means you have to be patient, before she takes all water
second shes about to flower// stretch, you may need more headspace and nutrients to keep her happy
open your tunnel and she will have a good airflow, and yes you can add fans if you dont open the tunnel
normally you dont have to fear surrounding hunidity, as long as the temperatures are above 20 degree
only continueing cold temperatures and high humidity are not so good, in flower
here some airflow is always an option
but for the moment i dont see big troubles, sepite having not enough to drink
feel free to look at my outdoor girls
