it looks to have started from the edges and I also notice yellowing in the other leaves. Did the plant get regular watering. I do notice similar situations in plants that have gone for a prolonged period without watering and then was suddenly given a lot of water - however when this occurs, it's not just the leaf buds that would have been affected but also the other leaves.

There might be something more systemic. Perhaps an insect that bore a hole into the stem interrupting the supply of nutrients and water to the leaves. You'll probably see more of that if the damage widens to the other leaves. However if you water regularly and notice the other leaves remain healthy, then it was a problem that's localized. Anyway, keep watering the plant regularly and observe it. It may be that this plant was just recently transplanted, interrupting some water to the tips of the plant. There are lots of possibilities. You just have to keep observing the plant.
