Heh, there is a straight answer, I already mentioned it. The old leaves were probably grown in a different environment then the one the plant is currently in. the old leaves will look bad, have no worries newer leaves will be acclimated to your environment.

good luck

For future reference:

Cuttings that are “topped off” like that never grow as nicely as a properly-taken cutting. A topped-off cutting comes from the end of a stem, where the stem is thinner/smaller and more delicate, and there is only one active growing region – the apex/tip of the stem. Also, the large leaves place stress on a plant that doesn’t yet have a well-developed root system.

A proper cutting will be taken from further down on the stem, where the stem is large and tough. All large leaves will be removed. And such a cutting has two active growing regions per node: Two nodes will yield 4 healthy branches.

See the attached photo of some cuttings I took just yesterday:

that makes 140% sense...thanks for the info, but, unfortunately, I didn't have a saying in the type of cutting when I ordered so...anyway, thanks fo the info, now I understand why my plant is growing so slow, I think I'm going to cut the two lowest leaves because they look almost dead

I also think I have to fill a tray with stones and water to put it under the pot so the humidity level is a little bit higher, I am starting to think that she is really struggling with this issue. I can see that the stem is nicely colored at the bottom but kind of dry looking towards the top...I am guessing that is because the roots are still small and the plant cannot take as much water as needed only from the soil and because the humidity is low the leaves cannot compensate for the loss of water...I settled for misting her a couple of times a day to help( at least that's what I think I am doing) until she spreads some "serious" roots.

If you(or anyone else) have more tips I would be more than happy to recieve them.

Thank you

and ringworm, that also makes a lot of sense, both of you shared precious info and it proved to be the right thing every time, but I am a still a little bit afraid for her future...mostly because of the humidity issue...I do hope that it's only an accommodation problem.

Anyway, I can't thank you guys enough for the information. It has been extremely useful.
