Hello, this is my first time posting here. I have a couple of Borneo Giant Alocasia's that I've grown for a few years now. I live in Colorado at 6,000 feet. The climate is dry and arid, and while the summers can get rather hot during the day, our overnight temperatures dip about 10 degrees or so more than most zone 5 climates. Usually around 55-60ยบ or so. These are not ideal conditions for this species of plant I know, but I love them and keep trying different things every year. In the past my plants start to go dormant by about January and then they don't send up the next leaf until about the middle of June. This year to get a head start, I built a small indoor grow room and they have done pretty well. They have been sending out new leaves all during the winter. Recently however I noticed some of the new leaves that have sprouted look very ragged and sad. You can see in this photo the larger leaf in the back has some raggedness near the bottom of the leaf and then the latest two leaves are completely ragged. Any ideas on what this could be?

Thanks so much.

It seems too near the glass door/window, and those areas are rather cold during cold season..maybe it feels too cold? What is the temperature inside the room?

Something seems to have damaged the leaves while they were still in the leave stalk.

Well, I only had the Alocasia by the window for about a week. I had been taking it outside during the day hours as we had about a week of temperatures into the 70's and even low 80's. Other than that it has been in my grow room for the entire winter and is back there now. I agree that it appears as if the leaves are being damaged somehow while still inside the stalk. In fact, I had one pop up about a month or so ago that didn't even have a leaf. Is it possible I over fertilized?

I normally wait for conditions to be more stable and warm to fertilize my tropicals. I don't do it during the cold/winter months. Especially if the plant is showing visible stress, I delay fertilizing.

You can also try and check the condition of the roots, or maybe it is due for a repot/new media if it has not been repotted for the past few years.

Was it putting up ragged leaves before you had it outside?

Thanks for the responses. I do think it's due for a repotting. I am waiting until the frost threat is over in May and then I'm going to try planting it in the ground. For fertilizing, I normally don't in the winter but since I have been growing them in a grow room I thought they might need it. Yes, some of the leaves came up ragged before I took it outside. Thanks all.
