My set up is a Vivosun 2x4x60 tent with 2 vs1000 100 watts each. I just started 3 germinated autoflowers one has popped out of dirt waiting on other 2. I have humidity dome on them. Humidity in tent is only 50%. Should I keep domes on after they pop out of dirt and if so how long? With the one that has spouted how should I go about watering? If I leave dome on do I just mist inside of dome or water around plant in scorched about an inch away from plant? Just don’t want to mess this part up. Here’s a pic of the one that has popped up.

I’d keep domes on after they pop out of dirt for a couple weeks. I also use a root stimulant to make sure my babies have a quick start. Especially with auto flowering varieties.

I would leave dome on do and water around the edge of your plant. Enough water so it reaches the roots. But I would not water near lights out. Best practices is water right after lights on.
Humidity is fine if you are using domes to keep plants moist during seedling stage. Also keep you lights about 24 inches from plants.
If you have not read the ILGM growing guide that is what comes next.

Looking great! I usually keep a dome on for about 2 weeks or until theyve got a set or two past the sucker leaves…

Looking good.
I leave dome on myself for a week or so till they get a set of true leafs. If the soil is nice and damp they may not need watered but once or twice the first week or so.
While it’s still growing roots it needs very little watering 
basically we are just trying to keep soil damp so it can establish a nice root system the first week or two…
Did you say “it scorched about an inch away from plant?” I’m a little confused by that line 
I dont see any light burn but there is a piece of the seed membrane stuck to one of the round leafs, this is perfectly normal and if you van remove it great, if not its fine also. If it comes off easy then remove it but don’t damage the plant if it’s stuck it will be ok.
