You might want to invest in a humidifier. From what I’ve learned recently you want to have higher humidity with those temperatures at this point of the grow, like maybe 60% minimum. Look into VPD (vapor pressure deficit) and if you’re like me, ignore the complicated science, lol. It boils down to aiming for the right balance of temperature and humidity at the different growth stages. There’s VPD charts and calculators and apps out there, I like the charts myself. These guys have a chart I really like:

And a nice little humidifier is the Pure Enrichment Mistaire. I actually just bought a second one, $40 on Amazon.
