Humidity issues

I'm growing autos in a 4x3, it's my first time growing and I've already planted my seed in my medium. Now that my pots are in the tent my humidity drops too 30-40% instead of the 60-70% I was able to maintain. I have a inline fan exhausting air and a humidifier in my set up. If I run them both my humidity drops and if I turn off my inline them my temp spikes and It doesn't do much to increase my RH. Any tips on how to increase my humidity before I resort to getting a better or more humidifiers. (If you need anymore info lmk) please and thank you all
