Growing Royal Gorilla by RQS

Well this week has been quite stressful ! Where I live has been humid as f...k and the RH in my tent is around 60 percent !!!! (week 5 of flower !! ) Even with a dehumidifier !! I m keeping a good airflow and low temps ( around 23 c ) hoping it will avoid bud rot or powdery mildew : //// !!! Does anybody have good tips to drop down that humidity please ? Besides that the plants are looking healthy and frosty and are starting to get bigger every day ! I've just been taking some fan leaves off now and then to expose buds to light. I hope buds are going to fatten up ! Happy growing y'all !
