Hey Mate,
I'm not a coco grower, but little plants require same things wether it's in soil or coco.
Growbie is absolute right, until they are in the small cup, I soak the soil before planting and then just spray water foliar evry other day. Due to the rootsystem is not fully grown, your damsels drink the most via its leaves.
So my suggestion would be:
Keep the medium moist, not wet
and give her water foliar until you repot. When you transplant your damsel in a bigger Pot, take care with watering. She still drinks not too much, so adjust the amount of water to the size of the plant!
Hope this helps a bit, have a good one!
