you exuast to the room the tent is? if you bought a dehum it has to be larage enough to control that room's cubic feet. So, it doesn't have to be in the tent. You could heavily defoliate / prune lower growth... that would also reduce RH. Exhausting to a different area not attached or easy flow back into the tent's room, and that too will help greatly. i don't know what would be better... reducing canopy evenly acorss entire thingn to get RH under control or removing na plant. I'd wager the even distribution of defoliation wil be better.. less proportion of larf and similar yield, if not better because you aren't losing sq footage of canopy. Target a shallower canopy depth. Take off in waves and see how it affects RH so you can maximize what you do keep. get a dehum.. use it in that room. it is an option. it's the better option, unless you only grow in seasons that don't result in this dangerously high RH for developed buds. I don't grow in the spring/summer for this exact reason. My climate requires less effort to maintain a good range if i grow in fall/winter. So, i scaled up to match fewer grow cycles, which comes with it's own cost savings and increased efficiencies too.

I have been in same position many times. Many times have tried to keep all plants but eventually have to give up. Earlier is better.

I grow in a small space. Over time iv learnt how to sort out RH. The room your tent/cupboard/growbox is the lung room. Depending on conditions in the lung room will impact the grow space. If you vent out of growspace into lung room then you are increasing RH in lung room which in turn will raise RH in growspace. Vent into a different room or outside will help lots. Growspace should be similar conditions to lung room, lung room 20c then growspace will be 20c plus the extra heat from lamp which will push it up so many degrees, example my lung room at 20c my tent will be at 22c during lights on, if lung room is 16c my tent will be 18c with lights on. Same with RH if my lung room is 50% then my tent will be 65% when full. So if you can control your lung room in turn your controlling the growspace. There are other things that help like defoliation, I'm in the mind set that when I have filled the tent and no light is hitting the lower growth then it might as well get cut off.

By killing one it will open up the other two for and provide more air flow, which should bring down the risk of powdery mildew. What’s the humidity on the outside of the tent? If the humidity is lower outside the tent, you could just exhaust more air to bring down the humidity. Do you’ve room outside the tent for a dehumidifier? because 75% humidity is in the danger area for problems, I’d be really recommending a dehumidifier.
