Hello everyone,

A few days ago I bought a Monstera plant from IKEA. It looked healthy until we brought it at home. After a week or so, black marks started appearing on its leaves.I attach a photo below.
Does anyone know what could be the cause of that and if yes, what could be the solution?

Thank you for your time and consideration, I appreciate any help you can provide.

Are the marks only on older leaves?

If you mean only the big leaves, no, they are also on some smaller leaves..
But there are also some healthy leaves. both small and bigger, and also some new ones that look healthy.

That looks like it could be damage caused by sunburn. Are these marks only one side of the plant, or all over?

I agree these could be sunburns. I made the same mistake with a Cordyline Australis that I bought from a store. It was under artificial light and I got it right in the sun of my window, having read that it is a plant that needs sun. What I did not consider though, was that not even a plant that loves the sun, can go under the sun rays if it had been in a different environment, with a different light source. So it got sunburns. Yours look like the same. I suppose it was also under artificial lighting in the IKEA store? This kind of plant like yours do not need a direct exposure to sun, they love a dappled, or partial shaded place, I keep one I have in a place where it gets a lot of indirect light, no full shade, but neither in the sun. Let us hear what other, more experienced members have to say. :)
In some Native languages the term for plants translates to "those who take care of us."

That type of leaf spotting could be caused by sunburn, as suggested previously, or by physical mishandling or improper watering. It appears that it is mostly lower (older) leaves that are affected. As long as new leaf growth comes in healthy and stays that way, you have nothing to be concerned about, although the damaged leaves will never heal.

Keep this plant tightly potted, in bright indirect indoor light and water it as soon as the top half inch of soil feels dry.
