Having one 'weak ear' is normal. And I've one too.
Like Simos said, keep on going, add all the equalising improvement tricks there are, keep your head warm, and do a lot of equalising on the way down every count 1. Start with a nose pinch to make sure your tubes are open at the start. And even assist your handsfree a little with it. Head position also makes a big difference. Do plenty of in deep water training, preferably in warm. Decent slow, keep up with the equalisation. Know that in the beginning being able to skip a few hands-on equalisations is a victory, but tiredness sets in quickly because the range of movement and strength are not adequate yet. A heads up FIM is a very nice way to train, and it's easy to have success in this way, and thus a good training programming the muscle memory. Combine the BTV with Fattah-Frenzel. Heads-down the BTV is tougher because one easily can have a vacuum moment in your mask, sucking the tubes into collapse where the remaining slime keeps 'm glued together making reopening very tough or impossible. Crawling on a sloping floor is good training and the middle of head up and head down. Take note of the times and actions it did work. Maybe some nose pinching btv muscle warm ups before diving can help too.
Learning btv makes regular equalisation much easier and better too. Enjoy!
