Deposit deduction

We rented a 3 bhk apartment. The deposit was 90k. The rent was 27k. It was agreement from aug 2017 to july 2018. We left the house in sept 2018. All dates 15th. From july, we stopped paying him rent. So it was 54k. There was n no increased rent agreement after june 2018. He asked my husband to increase it by 1k. To what my husband said, is it necessary to do it only for two months? He said let's see it later. Now we painted the house. We repeatedly asked him, if there is anything else u expect us to do? He said no. This is fine. There won't be any problem. Cleaned everything. There was a bathroom mirror broken, which we didn't repair as it was a builder problem. And many apartments in the society had this happened in their houses. So not our fault. Now this owner, after taking the keys, stopped responding. For a few days, i was just calling him. Finally got ahold of him. Now, he is saying, the house is not in the proper condition. he can't give me full deposit plus he is going to apply increased 10% rent from june. Amount due was 36000. He gave me a cheque of 32000. Can he stop payment of cheque? Can owners deduct the money they want? we haven't paid our electricity bill yet.
