It's day 5 that the seedlings begin sprouting. The rockwool has been moist for 5 days and inside a humidity dome being misted by me. This just appeared on 2 of 12 rockwool cubes within the last 6 hours.

Maybe its a deposit from the water I keep misting the dome with? Im thinking of scraping it off and spraying the rockwool with a H202 solution but if this is mold what should I do :(

Thats why I switched to Sure to Grow for the little starts. I dont like STG's bigger cubes and bucket fillers though. But STG is completely synthetic so you dont have natural substances atracting mold. Ive never had your issue though even when I was using Grodan, So it might be your overmisting your humidome.
 
I'm already constructing a cover for the rockwool as we speak, but should i:

-remove the 2 infected?
-scrape the mold off and hopefully covering it stops it?
-spray it with something?
 
It's probably just an algae.

Do the covers for the rockwool to block the light.

Enough with the misting and humidome. Get some air in there and quit being so happy with the water.

The seedling itself looks fine.

I would scrape off any mold myself first. IF all your plants are that under your humidome than Wet's right, you dont need the dome anymore. Your seeds have cracked and your starts have already taken root. Your dome is no longer needed. Get more ventilation as your mold is an indicator of future humidity problems
 
Ok, I'm still making the cover for the rockwool and going to pinch off the white stuff.

Will followup with a pic and more information~
 
Powdery Mildew.... and yes, a H2O2 spray will take care of what you have there. As others have said, it's time to get rid of the dome.
