Hi! This is my first time posting here so forgive me if I haven't done it right. About two years ago I acquired a colocasia mojito in San Francisco and brought it home to northern Nevada (very arid climate). I have it in a north facing windowsill with a grow light nearby for 12 hours a day, a humidifier set to 70%+, an infrared heater to keep the room at 70°, and I'm sure to water it once the top soil begins to dry out with good drainage. I also purchased a heat mat to put it on but it hasn't arrived just yet. Since I've had it, all of the larger leaves have died off and each leaf that comes in is much smaller and I can't seem to get it back to a bigger size. Right now it's winter so I know it's dormant, but even in the summers it doesn't seem to get much larger. What can I do? It's looking very sad at the moment and I'm so scared that I'll lose it! Photos from right when I first got it to where it's at now.
