You can Try getting some air tube extensions lines and run the pumps just on the outside of the tent and that’ll drop you humidity be 15-maybe 20 right where u need it since u leave ur tent open. I know that might sound crazy but if you put your hands on the pump itself you can feel how hot it is and realize how much temperature it’s actually putting off into the tent along with your light. where the heat is higher like summer it’s preferred temperature for veg so that’s why it hasn’t been an issue and it compensates the summer, but tricking your plants to think winter also challenges that which means lowering the temperature 10° or so would be all it needs to think winters coming. I live up north and have plenty of times grew weed in feet of snow . I also have a friend who lives in Afghanistan and his temperature never goes lower than 70 and still grows just fine because they’re photosynthesis mainly. Good luck to you but I can try to help with some advice you don’t have to take it I’ve just seen people who Aqua grow pull there pumps outside to lower the heat during flower and it helps.
