New leaf not opening and going limp?

This new leaf on my large #philodendronimperialred has been growing for nearly a month now, and it just keeps looking sadder and limper... I haven't changed much with its situation, it's in a self-watering planter so gets very even water, and it lives under the grow lights in my room which is more light than it used to get from behind the folding screen. One of the leaves snapped off recently from age and the plant might have gotten stressed from that, but that's all that I can think of that changed. What could be causing this and/or what's wrong with it?
2ft to light, indirect
6โ€ pot with drainage
Last watered 1 month ago
Howโ€™s the humidity? Sometimes philodendrons tend to get stuck and misting their leaf may help them get unstuck. I like to mist my stuck leaf, rub with a cotton swab to โ€œencourageโ€ it to move and the next day the leaf will most likely unfurl.

Only other issue I can think of is possible problem with roots or pest issue, which Iโ€™m not sure about. ๐Ÿชด
@dreamlettuce is Right.
โ–ซ๏ธLow humidity maybe responsible for that unfurl leaf.
โ–ซ๏ธpests could also be the reason. When I enlarged the image of your beautiful Philodendron Imperial Red, I noticed some white spots on the leaves. ๐Ÿ˜ฎ Those white spots maybe powdery mildew or mealybugs or spidermites. ๐Ÿ˜ž These pests are stealing the plantโ€™s nutrients, weakening the leaves and stopping its unfurling process.
โ–ซ๏ธTake a very close look at your plant leaves. If the white spots are a pest infestation, then asap QUARANTINE this plant away from the other plants in your oasis. Inspect your other plants to see if theyโ€™re okay.
โ–ซ๏ธClean your leaves using water or insecticide soap. Spray your leaves with neem oil or use one of the many chemicals fungicides on the market. This website will help: https://thepracticalplanter.com/why-does-my-philodendron-have-white-spots/
โ–ซ๏ธI hope Iโ€™m wrong and I hope your beautiful Philodendron Imperial Red will quickly recover, live long and prosper.
I agree with @kscape. I have a prince of orange philodendron, and when the leaf was finally opened, it went limp the next day. A few days later, it picked itself back up and this is it now. Leaves are weak at first until they grow to size and harden. But it does look like the end of your new leaf might be dry
@Ada3 Ahaha, thanks for the concern, but it's just dust! I have good eyes for tiny stuff and can see mealybugs or spider mites with my naked eye, so I would have noticed that first. Just to be sure I checked, but it's definitely dust ๐Ÿ˜‚ But that certainly makes it seem like it's definitely too dry, what happily humid plant will be dusty? Sorry for scaring you!!
@dreamlettuce @Bplants I didn't even think about it since my Prince of Orange leaf hasn't wilted like this, but it's also taking a while to open and it's not sitting in the path of a fan like the Imperial is ๐Ÿฅฒ It should be only mild fanning but with how big it is it certainly can't help. The meter says my room is... 47% humidity, oh no.... that must be hitting the big guy worse than the little ones that can huddle together and humidify each other.

Thanks for the insight, I'll mist him (and Prince) a bit over the next while, and keep you guys updated if things change!

Ahhhh.... sadly, the leaf fell off today. it was very limp, like wet tissue paper..... the middle wrinkled in a strange way? It's a little sad after watching the leaf grow for so long, but these things happen I suppose... I hope the new one has a better fate!
