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

You may want to try putting your inline fan on a timer so it's not running 24/7. Although, you mentioned heat issues. Is your grow light dimmed down?
Looks like a decent size humidifier for the tent. Is your fan 4" or 6" ?
Maybe a cheap solution would be to put your fan on a timer switch so that it runs for like 5 minutes then off for 10 or something?
It could be my humidifier being to small, my inline is on the lowest setting but I have negative air pressure in my tent. My set up is in my closet and it's a little bit of a tight fit. I think I'm gonna put some domes on the seedlings to try and keep my humidity up. But here is a picture of the inside of my set up if it helps
Getting it to balance can be a pain. I'm using the AC Infinity system with digital controller now so it's more automatic.
With seeds and seedlings you can run humidity pretty high. An easy way to do that is to put a dome of some sort over them. You could cut up a 2 liter bottle and cover them to create a little greenhouse. I do something similar and always have happy seedlings. This would also buy you some time to dial in your tent setup.
Does your fan have a speed controller? Maybe it's just a matter of getting the system balanced so that the humidifier can keep up. It sounds like you may be exhausting too much.
Maybe your humidifier is just too small?
Tent location matters. If it's in a closet it's easier to keep that space more humid so that it's pulling in more humid air.
A quick way to raise humidity is to use a spray bottle to spritz in some water onto the tent walls but that's usually a very temporary fix.
A bucket of water with an air stone bubbling could help some if you have room for it in the tent. It also serves to dechlorinate and aerate water to feed the plants, or you could make compost tea.
Balancing heat exhaust and humidity can take a lot of trial and error and it becomes much more difficult in more extreme climates. Automatic fan controls help a lot but they're an investment.
I used to struggle with heat but then I upgraded my lights to a fixture with an external driver that I've put outside the tent, heat is no longer an issue for me.
