Q.Why do the red flowers of my anthurium never turn red?
the leaves and flowers grow out well but the tips of some leaves turn brown and the flowers start to turn color but then wilt and die long before they turn red.

There are a couple of things that could be happening here. Disease from overwatering is one possibility. The other possibility is a high nitrogen fertilizer. This will burn leaf tips and prevent flowers from forming properly. Both issues can have the same symptoms, but they will show in slightly different fashions.
