Nail discoloration

I wasn't quite sure if anyone could tell me what this is

im not sure what is going on with the tip of my nails or if i should even be concerned

Does anyone have any ideas?

Please anyone ?

Very difficult to tell. Is this all your nails or just the one shown?   It could be the start of a nail lifting but it could be quite normal. You are obviously concerned so a visit to your doctor would be a good idea.
