humidity up to 90% after switch to 12/12 - help!

So I put ventilation, intake and circulation fans along with both lights on timers, but I left the air pumps running ... figured it probably is not good for the roots to sit in non, oxygenated water for 12 hours.

This morning, I open the tent after the lights kick back on and there are drops of water on leaves and the walls of the tent are dripping wet. Do I need to keep the intake and ventilation fans on all night when the lights go out?

Thanks in advance,

Yes, ventilation should happen 24/7 (I don't just mean active, it can be passive as well). But more importantly, in your case, I would try to do something about the humidity because you don't want the humidity to go too much higher than mid 50's during the blooming phase if you want to stay on the safe side. You can also help the cause by reducing the plant mass (defoliating to reduce the surface area). High humidity also contributes to carbon filter not working as effectively.

Is it normal for humidity to sky rocket during the dark period? I assume it is because of my air stones with my squirrel cage fan turned off ...

I don't know about skyrocketing but I would assume that the humidity present in the room has nowhere to go if you do not have any passive ventilation available and you have all active ventilation gears turned off during the dark period. I would first start off by taking the ventilation equipment off the timer and let it run 24/7. Then document and see if this works out for you.

get a dehumidifier yes humidity spike when lights are off, i would also say that your lights off temp is to low by the fact the the dew point was reached and collected on hard surfaces, i would also recommend wiping the room down as well as your buckets/pots with a weak bleach solution to prevent any possible fungus/mold growth due to said humidity reaching the level it did

Why do you turn of your air stones during the dark? Leave them on 24/7

Are you sure it's 90% ?? Seems like if it was you would have condensation everywhere.
