Moldy soil? Please help!!

This morning I went to go check on my babies and noticed the soil was a bit greener than usual. I suspect this to be mold, its occurring in small patches in 2/4 pots, but I fear it might spread. Can someone please confirm and advise what to do next, and how to prevent this from happening again. Thank you!

PS: The plants themselves are fine for now.

I'm also experiencing some kind of deficiency I presume on another plant (3/4 - Not related to the moldy ones).
Its on a lower fan leaf and its the only one with those symptoms on the plant. The same conditions are applied as the above.


Any help is greatly appreciated! Thanks again!

it's moss-relax!..the spots may be light burns....indoor leaves are tender.

Thanks for the reply, so I'm guessing its not harmful to the plant, but should I take measures to getting rid of it?

there's a book called secrets of the soil, by tompkins and bird...it will change the way you think about soil, and point you in a more wholistic direction.
