I don't think I would worry about the leaves splitting. If the bulbs are swelling, that is probably a good thing, and the leaves not being able to get out of the way may be less than desirable, but not of any particular consequence. However, it looks to me like you may have had several growths in a row that are much smaller than the original bulbs. Just a little smaller would be OK, but these seem much smaller. I think that it is indicative of less than desirable culture. Maybe not enough light (or too much), or maybe drying out too often or two hard. It is hard to tell what could give the plant better culture, but the last things I would worry about are fertlizer and humidity. They are usually the first things people think of, but from my experience are probably the least important.
