Adjust one month rent from security deposit

I have given my owner the notice tat I wil be vacating by end of Jan 2016.as per agreement I have given a months notice. I stay with my family,and have always paid rent on correct date since the first day. Now I have requested him to adjust the last months rent from the security deposit.(owner is having 2 months deposit,I am opening with last month rent only) Agreement clearly says ,deposit wil be returned after 1 week from vacancy only after deducting DUES,DAMAGes,loss against property or maintanence. Owner wil be still having a months rent with him to deduct anything after deducting a months pending rent. In this scenario, m not breaching the terms ,I am only asking to extend some time for RENT and deduct from deposit instead of returning it. Can owner ask me to vacate the premises with immediate effects?
