Heya!
One thing to consider with temps and humidity as well is you want to make sure your VPD matches up for optimal growth. In general:
Vegetation: Day temps: 21-27C
Night Temps: 17-22C
Humidity: 55-75%
Flower: Day temps: 21-26C
Night Temps: 17-20C
Humidity: 45-55%
As far as the optimal humidity and temp, I always follow this VPD chart and seems to work really well! (https://www.cannabissciencetech.com/view/understanding-vpd-and-transpiration-rates-cannabis-cultivation-operations)
Cheers and good luck!
