Tracy,
Did your Discus look like the pictures before you used the Chloramine T. If they looked like this before the Chloramine T , its not going to help. You have a serious bacterial infection,or protozoan infection, or possibly a virus. WE need more information here..
1. How long have the discus been sick?
2. How long ago did you treat with Chloramine T?
3. When was the last time you brought fish into the house? any kind, not just discus.
4. You said you added plants, when? and where did they come from?
As the others advised... stay away from the chloramine T.. its not a good medication for Discus treatment, Koi tolerate it better and harder to overdose in a koi pond than in a discus tank because of how it reacts with organic matter.
At this point, I am afraid it looks like you may lose some more.. I would do a very large water change and add salt at 1 tablespoon per 1 gal aquarium water. Doesn't need to be "aquarium" salt, regular table salt is fine. Maintain that concentration for the next several days. Do daily large water changes and replace the salt to maintain that concentration.
