If it's "white, hairy like fluff, with the texture of cotton candy", it doesn't sound like mineral deposits at all, but rather a mold or fungus in the soil. You say it's on both your herb seedlings that you have in plastic, as well as your houseplants? What about watering .... how often do you water your plants? You may be overwatering also. It sure would help if you could post a photo. There are so many knowledgeable people here on DG, I'm sure someone would be able to look at your photo and give you some suggestions.
Keep us all posted as to how your plants are doing. I have been growing house plants for nearly 40 years and mine tend to thrive on neglect. Many years ago I killed everything from over watering .... now I keep everything on the dry side and they seem to do much better. In the winter months, I only water every two to three weeks.
