My first grow - 2x4 tent

Just noticed a pollen sack on one of my plants!! Not sure whether I should keep it in the tent or not.... I have three plants and only one had them. It is the one that has been showing the most stress this week. Adding a second light increased the temp to 91 at times and the tallest fastest plant had the tip of the leaves start to curl, indicating heat stress. I also took a couple of fan leaves off of each plant a few days ago, maybe it didn’t like it? Any recommendations on keeping the plant in or not? Update: I took the hermie out the next day when I saw a couple more pollen sacks.
