High temperatures and humidity. Genetics??

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

You VPD is Ok!

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 ?

Some seedbanks have categories for mold resistant or types of climates- this is where you'll find the stains you're after.

high humidity could slow evaporation of terps/flavanoids. slower evaporation = less smell. Some plants just don't smell much unless you agitate them -- don't agitate it, lol. but, if you shake it a little bit, i bet it stinks up the area. Due to all the interbreeding, anyone source telling you specific traits like that is probably lying or lying to themselves. Could look up where various strains came from and hope they haven't been interbred withplants outside that region where it evolved... someting near equator, for example, is better equipped to handle high heat, i wager... but the seeds you buy are all hybrids and interbred.. jumbled up traits. word-of-mouth is your best option and that is incredibly unreliable, lol.
