Braided Money Tree

1. we used to water the pot twice a week ,later we bought a water sprayer two or three weeks back and started spraying the whole plant .its leaves turned all of a sudden yellow
2. we maintain a temperature of 80 in our AC room
3. it do not get more light as much as through a open window ,it is far from the window but not too far.sometimes i turn on the light so that it can get enough light ,but i dont know whether it is neccesary or not.
4. it used to be twice more than, as it is shown in the photograph
5. i want to know why it is happening to her and how to water her and to take care of her

Thank you very much
