I assume you mean Maranta, which like the so-called peace lily or Spathiphyllum wants evenly moist potting mix, meaning neither sodden nor bone-dry, and high humidity. If the soil moisture varies widely, the air indoors is dry, or if you’re over-fertilizing, that can be trouble. (In winter I don’t feed at all; unfortunately, a lot of the potting mixes people use these days are loaded with fertilizers.)
All of these factors––soil moisture issues, low humidity, and excess salts from plant food–can caluse what you describe. Never leave the plant sitting in a dish of water; let it drain thoroughly each time you water. Frankly, I think all these factors are key for most houseplants, but some show their resentment more obviously than others.
