Is the Atmospheric swing my issue here?

So I have a veg room and flower room at opposites sides of the house. Veg room stays at about a constant 75 degrees; everything looks amazing, green, and healthy. After the veg room they are moved back to a 10x10 flower room with 2 1000w king cobra hoods. The temps are in the mid - high 80's during lights on and drop into the 70's during lights off. The plants being grown are split with me and a partner. Both using completely different soils, nutrients, and grow styles all together. But they are both showing some of the same issues. Fan leaves are dying and falling off, and the ends of the leaves are curling up. Showing almost a nitrogen burn, but like I said we are using totally different methods and nutrients all together. Only thing the same between our plants is the atmosphere. Could the 20 degree swing in temperature be what is causing this problem? They are literally flawless in veg, and don’t start showing signs till they get to the bloom room. Giving rep for good responses, please chime in, anyone who can help.
