There could be something bad going on in the sub. I wouldn't bother it you may kill everything in the that if it's a dead spot.
HC carpet 'bald spots'
So, my HC carpet grew in in about 2.5 months, and was doing really well, but now there is a bald spot forming in the center; now it happens to be directly below where some taiwan moss is growing on driftwood. Am I just seeing a shaded area where it is not able to grow?
I also sometime see the rainbowfish pick at the carpet, but not specifically in that spot.
Think its just being shaded out?

Was it yellowing there first? A bald spot sounds strange. If you saw it yellowing and dying and decaying that's one thing. Just gone is another.
Are you saying you think a part of the substrate is anoxic?There could be something bad going on in the sub. I wouldn't bother it you may kill everything in the that if it's a dead spot.
The whole thing was yellowing about 3 weeks ago, but i bumped up the iron and most of the carpet recovered within a few days, and then this started to happen. It does only seem thin in the darker areas.Was it yellowing there first? A bald spot sounds strange. If you saw it yellowing and dying and decaying that's one thing. Just gone is another.
Yes if you mean toxic. Decaying matter under the gravel will sometimes build up and create dead spots in the sub. If you disturb these spots the dissolved gasses will be mixed around and kill anything that is alive in the tank wether is be fish or shrimp, etc.Are you saying you think a part of the substrate is anoxic?
Some people uses snails such as MTS or malaysian trumpet snails that over time mix up the sub. which leave you with small tiny pockets or no problems what so ever.
It's also referred to as something else but I forget what it's called.

Well, two things; first its only 2 months old, so I doubt there is enough stuff built up to form hydrogen sulfide pockets. Second, I have malaysian trumpet snails. Third, I use fluorite, which is quite large, and I doubt it would go anoxic very easily with such large pieces.
Anyone else have any ideas about why I'm getting the bald spots?
Well if the dead spot is in a shaded portion then its most likely a lighting issue because HC wont travel into the dark areas. Typically it is a high light plant, that was the case for me anyways. My 2cents.
Turns out the CO2 was just too low; the carpet and stem plants had filled in so much that they needed about 30% more CO2. Turned it up, and everything is returning to normal.
