I have it cascading from pots but the top leaves kept turning brown. Could it be sunburn? I do also have the same in a shaded area with the same problem. What causes this?

If the same symptom is appearing in both plants, it is unlikely to be sunburn.
If the browning is just at the tips or around the edges of the leaves, see this article:
Brown circular spots or brown fuzzy growth on the leaves is likely a fungal or bacterial disease. If none of these fit, and the whole leaves are turning brown and crispy, it could be lack of water or simply that the plants need pruning to remove old sections.
