Calathea Trouble

[RachInCo]

Hello - I’ve had this Calathea for about a year and it was beautiful for the longest time but the leaves are browning around the edges and new growth is coming up with brown edges. I’ve replanted in a moisture control soil and moved to more light but the problem seems to be persisting. What would help this poor struggling guy?

You need a humidifier and distilled water. They need very high humidity and hate salts or minerals in their soil. The whole group of Marantas, Calatheas and Goeppertias are rather touchy about both.
