Hey @kan1979 welcome to AG and congrats on starting your first grow. I’m glad Todd requested a picture as your coco pod is sitting way to deep. The top of the cocopod should be flush with the top of the reservoir lid, not sitting down inside the whole like yours is now. Very carefully push it up from the bottom until it is even with the top of your reservoir lid. This is very important as it is currently picking up far to much moisture from the liquid in your reservoir which can cause various negative issues with your grow. Again, be very gentle when repositioning your pod, they are fragile and can break.
As for your seedling, I would let it be for a couple more days and see if it pops. If not by day 10, you can pull back the piece of coco pod that is covering it with a pair of tweezers and take a peek inside.
