Thanks for all of your help! And thanks for kicking me in the ass to post here lol.
I did buy a small humidifier and had it running in the tent, but it kept building up this white film on everything inside the tent pretty hardcore. From the limited research I did, it seems like it was calcium buildup from the hard water that we have in NY. I since moved it right outside the tent and have not had the same issues, but unfortunately it is not as effective. Maybe I need to run better water through it?
If it is an ultrasonic humidifier you need to run distilled or reverse osmosis water in them. If not they vaporize all the dissolved minerals in your water into the air. That is the white dust coating you are seeing.
I would advise watering/presoaking the entire pot. Those first few days the seedlings are putting down some long roots. I typically presoak and then let the seedlings alone for the first few days. I don't think you need to water to runoff but perhaps get the pot a bit more moist throughout. They may be small but if you learn each time and progress in your growing you'll get great plants. Germination went well and that's one of the hardest parts.
