If you have added anything to them recently, then it might be responding well to the treatment. If it was stressed and just now recovering, then this would indicate healthy growth. The same happens with my indoor citrus after having to cure a round of spider mites. Once it recovers it will start to grow much larger growth.
As for the bitterness- There are several causes to consider. If they cross pollinated, then this years fruit will not be affected. This will only show up in then next generation after starting new seeds from one of the parents. What could be happening, though, is usually environmental. This can indicate pH issues or nutrient needs, as well as soil quality problems. Sometimes specific cultivars can be more bitter.
