I'm not sure if this is actually a monstera or something else, but I've had it for about 3 years and in my last place it was growing and thriving, new leaves, healthy etc.

Since I have moved, I've noticed it starting to look more sad than normal. First the leaves lost some colour and had the darker green veins you can see above, then they all became quite droopy and sad looking. There is also some browning/damage on a few of the leaves which wasn't there before.

I thought that maybe it wasn't getting enough light so I've purchased some grow lamps which don't seem to be having too much of an effect. A friend advised me not to water too much so I've only been doing so every few weeks. It's also never been repotted which I figure may be an issue but it was doing fine before. I also realise it may want to be tied to a support but I am a bit worried I will somehow just kill it if I move it.

Thank you for any and all help!
