At 50% humidity and 78 degrees, you are at the high end of VPD. Anything over 78 and you are in the red…VPD wise. You could either lower your temp or raise humidity. If you raise humidity be sure you have a fan moving the plants around a little. I would lower your temps and take the pressure off the plants.78-85 degrees 50% rh. I’m upstairs and it gets warm. Feeding GH trio and pk booster cal mag and microbes. Tried advanced nutes, dr earth organic as well. I’ve gotten harvests outside no problems, and indoor autos. It’s just the photos that go south in week 3-4 of flower.
