I agree with Elaine. I sounds to me like you are drowning the plant's roots, both from too frequent watering and perhaps a water-retentive potting mix. This is a good time to re-pot. Purchase a good quality potting mix, but to give better drainage, either add a cup of coarse perlite or orchid mix to every gallon of potting mix. Slow release fertilizer is a handy way to fertilize, and I use a lot of that. I still fertilize quite frequently with a diluted, soluble fertilizer from spring till fall. Since I grow so many other tropical plants, I am always fertilizing something.
I use 1/2 the rate (1/2 tsp./gal.) during the spring and summer months and 1/4 the rate during fall and winter months. Remember this phrase: "Weakly-Weekly".
Also, be sure you dump the water out of the saucer after every watering.
