I'm gonna do my spring cleaning cure for houseplants. After a winter sittin in the house plants get stressed and tired looking. Looks like the plant needs placement in another spot warm 70' yet indirect light, it looks like it's shed a lot of leaves.
Keep plant away from fans, heat, drafts will dehydrate the vegetation causing them yellow and drop as overwatering to and causing soggy soil.
Also this is a good time to repot house plants. Most house plants have exhausted the old soil and by adding some new well draining soil ideal for the plant will help start new growth. Also weaken fertilizer by 1/2 each time you water. Of course if there are any scale issues or root nats or diseases do not fertilize until plant has recovered from any infestation.
Also you can take the plant to your county extension service and a master gardener can see the plant to get a better picture on how to condition the plant & diagnose any issues we can't see in pictures.
Just a few things to think about to outweigh like cancelling out one thing as you go along until the plant improves. Sometimes less watering and checking the soil for root or soil bugs and while replanting also loosen roots check to see if they are root bound and clean out any dead roots. This will help recharge the plant in a few months you'll see a lot of new growth and improvement.
