Hi
Did you flush with plain water or very low nutrient water? Its best to do the seedling dose nutrient flush for any future flushing.
Usually you want the last bit of water to have a normal dose of nutrients. With your soil being soaked id say either bring in 1-.5 L of nutrient water and then increase air flow, or increase air flow and then wait a day for it to dry out a little bit then water with nutrients. Either way you don't want to leave coco bare for very long...it has nothing. It even needs calcium from day 1 which lots of other mediums dont.
Happy growing ✌️
