What is your ph and light ?
A dome over your seedling will help get your rh up to a better level. ( 60-75% )
Coco loco should be 6.3-6.8 with 6.5 as ideal.
@Oldguy thanks for responding and my ph was reading was 7.0. I checked it with a soil tester that you stick in the dirt. I have a 8×4 tent with two 1000w leds. I have both lights in veg mode. I had the solo cups covered with a plastic bag until they sprouted. Should I cover them back up with the plastic bag? Also should I try adjusting the ph level of the soil.
Those cheaper soil testers are only vague at best. A proper digital one is almost mandatory for indoor growing.
Ph should be at or close to 6.5 going in for water.
I wouldn’t try adjusting the soil due to the buffers put in during the making of it.
And yes put the bag or a clear cup /pop bottle over them.
They get their moisture at this point through their leaves. They are still developing roots. So easy on the water or they could drown.
@Oldguy ok I’m going to put plastic bags back over them and make sure that I invest in a digital meter. I’ll ease up on the watering and see how the ladies respond. Thank you for your advice. I’ll keep studying as well to increase my knowledge.
@GrowforGold. Any time friend. 
We all want to see success.
