I potted plant into chc and watered once a week. After a while I noticed a new growth which is growing into a pseudobulb. Now I think it can be logged in here, since there is a chance plant will make it:

Old leaves still have the black and brown patches, I monitor them to make sure they don't get near the new growth, but they seem to stay the same.
Cattleya araguaiensis is still on my wish list, but that would be a blooming sized plant I want to get.
