She's starting to turn color, softing and shrivel. I've been watering her every Tuesday and I leave her on my window sill all day long with shade as well. I know that I do need fertilizer for her and if she does have pest what can I use?. But I don't know what I'm doing wrong. (I inserted a picture of her pot she's in) Please help me.

This looks a bit too organic to be watered every tuesday, even for something like this...
Does the pot have holes? Have you checked the roots? Did you water after repotting?

skopcollection, I don't think I watered it after repoting it only has one hole the size of my pointer finger and her root system feels dry. I use true lining professional potting mix with fertilizer.

I don't think fertilizer is the problem if you're using fresh mix. Usually potting mixes have plenty of nutrients for a couple of months when fresh. I'd say just report it and soak it through and give it about a week to see what happens. Also, like previously mentioned, it isn't a problem here but terracotta does retain more moisture because of how porous it is, for future reference in case there are any problems with rot.

I doubt that potting mix with fertilizer matters much, I use potting mix like that all the time and the fertilizer washes out pretty quickly. No need to add extra fertilizer though.

I suspect that given the pot size/root mass that there is very little actual soil in the pot that can serve to retain water. So I suspect that watering weekly while seeming like a lot actually does not provide the plant with that much actual water. The vestigial leaves drying out and changing color combined with the wrinkling suggests that - though the color changing on the leaves could be due to a change in sunlight exposure, but if this plant is kept inside it hard to really think that would be the main cause.

I would find a slightly larger pot (not too large) so the roots can be encased in soil a little better, I think soil needs to be a little more water retentive that the current pot allows for and then only water when the pot is almost to completely dry. Then stop messing with it. The roots like fine and healthy so the less you disturb them the better.

Aside from that, the narrow new growth suggests the plant is not getting enough sun by far. I grow this plant's plant big brother (it is about 7ft tall) in half days (about 7 hours) of full sun in the desert here. It is showing some sun stress, but generally is taking the sun quite well (I water thoroughly once a week at the moment), so once it is back to looking plump and less wrinkled (some of the leaves will shrivel up and be lost from the plant - that is normal they tend to be only a feature on the newest growth on this plant), you should see about giving it some more direct sunlight especially if it is behind glass.
It is what it is!

Yes, that pot will not hold much water for long. On top of the size, the fact that it is unglazed clay means it will dry out by evaporation through the sides as well as the top, and if it gets strong light that process will be accelerated. So there's a limited holding capacity and a rapid drying out process. Watering weekly would probably mean the soil is still going bone dry in between, at least at this time of year in strong light. You can check this and probably should when you repot the plant, so try to time the repot for a day or two prior to when you would normally water, and then you can see the actual soil moisture by observing it when the plant is out of the pot, and assess whether your intuition was correct. Thijs made a good point about watching the leaves on the plant, as another way of checking this intuition.

Clay pots are especially different from plastic pots when they are small. All clay pots will dry out faster than a plastic pot of the same size, but this effect is more dramatic the smaller the pot gets. That is why I actually never use clay pots smaller than 8", because I prefer not to have to water any more often than absolutely necessary.

I understand the advantages of clay pots are helpful in avoiding rot complications due to excess water, and in some places they are pretty much necessary to help keep succulents going strong. So don't go plastic if you like the clay. This is just a note relevant to the consideration of volume, when choosing a pot for your plant. When in doubt take small steps, like 1-2" at a time, and make sure the new pot is wider than deep (or underfill it).

Thank you guys I'll go for plastic for now on and I did notice that whenever I watered my plants the clay would soak up most of the moisture and the soil will dry out faster. I did change my soil to succulent and cactus only now I'm just waiting for my plastic pots to come. As a new plant mom I can take all the information I can get.
