You can try updating the application or most of the time, you won’t find blue ticks only for a particular contact because they haven’t upgraded to the next version of Whatsapp.

Check your settings , in accounts-> privacy, there you will find option for " Read receipts " tick the chechbox. Now you can see blue ticks!!
