It seems that the soil remain a little too moist. They need the top inch of the soil to dry out, pretty thoroughly, in order to preserve the delicate balance of microbes in that soil layer. Too moist of soil invites anaerobic bacteria that survive without oxygen. This leaves good microbes unable to defend the territory.
I would keep a close eye and make sure that the soil has a chance to dry out on top. Make sure, as well, that your container has drain holes and can allow all extra water to leave it, freely.
