Bone Meal And White Mold Top Of The Soil

Hello,

I added meat/bone meal to potting soil (2 tablespoon/gallon).

after 1 week, i began seeing white cottony molds top of the soil.It smells like mildew.

Is it normal ?

What is the wrong ?

Thanks

make a mix of 1 part milk to 8 or 9 parts water(10-15% milk) and spray it where you see mold..also let the soil dry out on top before you water
