If the bud is hanging on for dear life then it should be removed. This is for the folks that dont know. Locs consist of hair and hair can be cut therefore locs can be trimmed. Ive seen many people with blunt ended locs from where they trimmed it. coily ends are different from loose buds hanging on by a strand of hair lol I do also prefer coilies. Let me get back on track. Your locs have had a growth spurt in recent times :)
