Hi Mark, yep, classic overwatering , you can tell by the puffy space between the veins of the leafs. The downward pointing leaf tips is a sign you might have water mold. At this stage in the plant's lifecycle, you can probably get away with it as long as you follow a very strict wet dry cycle. Try squeezing the medium a bit to "unlock" pockets of humidity that might take too long. Hope this helps ! 🚀
