You VPD is Ok!

If your temp is too hot and you can’t decrease it, you must add co2, your plants gonna be on top with hot weather and co2

If hot and no smell you cooked terpines, something wrong, heavy wrong. I had temps up to 40 celcius in grow room, still all neighborhood was stinking at end of flower , BUT Few times i had root issues, ph issues or heavy overfeeds - then i was loosing smell in growing phase, not drying even ( where most terp overcook mistakes happens ) so maybe issue is in other place ?
