Help my prayer plant

"The prayerplant prefers well-drained soil and requires high humidity to thrive. Prayerplant houseplants should be kept moist, but not soggy. Use warm water and feed prayerplant houseplants every two weeks, from spring through fall, with an all-purpose fertilizer."

Below is a website (blog) where people talk about different things with this plant.

Try a little more sun, rotating it toward the direction of the sun, and a few drops of cool coffee, also a few grains of fertilizer every two or three weeks. Don't overwater it. An artificial light bulb nearby might help. Say a little prayer, God loves all his creations.

Get a moisture meter to make sure you aren't keeping the plant too wet or dry, it really helps. If you have a lamp near it, get a grow bulb or a daylight bulb. The daylight bulb has the whole spectrum of light, but is not as intense of a light as a grow bulb and cheaper. This will give it the light it needs to stay healthy and happy in your low light in your house. I use them for my five pots of hibiscus and they are staying really green and happy. Make sure to give them the fertilizer they require as directed. It wouldn't hurt to mist them occasionally.
