There could stem rot which may not be explicitly visible. By the time you recognize it most often too late. If there is yellowing of the newer leaves then thats for sure that there could be stem rot but if bottom leaves are yellowing it can be hard to recognize if there's stem rot. If you lost more than 2 leaves quickly that also might indicate stem rot. One of my phals I was able to save at the right time. Even I water very carefully but there are times mistakes happen. As soon as I saw one of the top leaves yellowing I tried to look for stem rot and when I couldnt find it I just decided to rip off the leaves at the top to locate the rot. I'm not suggesting that you do the same but just check and see if you can look for stem rot. Since you are saying that the plant is healthy in bloom, new branches and healthy roots I have a strong feeling that there could be stem rot. For me luckily the rot was above a set of bottom leaves. I cleaned up the rot and dabbed cinnamon powder now its recuperating pretty good with the bottom leaves.
