Your plant looks good. Cactus, above poster, is telling you to re-pot because the soil used by the plant growers is not the best for succulents. Most often suggested here is commercial cactus and succulent mix combined 50-50 with perlite or pumice. That size pot might be OK unless you find it root-bound. Remove all the old potting mix from the roots when repotting.

If you cannot get out to shop for the proper potting materials, your plant will be OK for quite some time as long as you don’t overwater. You can check to see if your plant potting mix is moist by putting a wooden skewer deep into the soil. If it’s damp when you pull it out, don’t water. When you do water, let the water run through the pot and out the holes. Nice plant, good luck.

First, repotting is different from potting up. It's more involved in that it usually includes bare-rooting, root pruning, returning the plant to the same pot, one smaller, or one larger - depending on soil choice. The more open (the larger the soil particles) the soil is, the less critical pot size becomes. The 3 primary considerations re when it is/isn't appropriate to repot are: 1) Timing - where the plant is in the growth cycle. Houseplants vary significantly in their ability to bounce back from repotting. While there are a few exceptions, most houseplants would rather be repotted sometime around mid-June. If you keep Father's Day or the summer solstice (June 21, annually) in mind, you can't go far wrong if you live in the N hemisphere. Working with your plant's natural rhythms instead at cross purposes to them makes good sense. In early spring, plants are usually still recovering from the adversities of winter which cause the plant to expend most or nearly all of its energy reserves. By waiting until mid-June, the plant will have substantially recovered from the outlay of most of its energy reserves; and, it will be entering into the most robust part of the growth cycle, when days are longest and light most intense. This ensures the fastest recovery possible, leaving the plant less susceptible to insects and diseases that are more likely to enter the picture during long recovery periods 2) Root congestion. At the approximate point in time where the root/soil mass can be lifted from the soil intact, important considerations like growth rate, vitality, appearances, and in some cases yields, begin to be negatively affected. The limitations increase in a direct relationship with the severity of the (root) congestion, and can rob up to 100% of the plant's genetic potential. Bare-rooting, root pruning, and a change to appropriate soil can work wonders for a plant and make you feel like you're a better nurturer. And if you think about it, the only reason we grow things is because we have that nurturing bone. 3) Existing soil. It's not at all unusual for a plant to arrive in a medium most growers would consider to be inappropriate. Sometimes a repot might be so needed that we're forced to overlook the fact roots aren't congested or the timing isn't right. For the most part, it's better to use a work-around until the timing better favors the plant; but, when you think the plant's viability is in question if you wait until mid-June, you occasionally have to 'go for it'.

Your sans is sensitive to fluoride, which is accumulative in tissues. IOW, once the fluoride is in the leaf, it remains there and accumulates until it manifests in symptoms at leaf tips and margins. No matter how often the horticultural myth about allowing water to rest in an open container so the fluoride can gas off is repeated, it simply doesn't happen. In fact, as water evaporates from open containers, the fluoride left behind actually INCREASES the concentration of fluoride. If you can, irrigate with rain water, snow melt, distilled water, or condensate from air conditioners or dehumidifiers. I use a small and inexpensive reverse osmosis filtration system for drinking water and water for indoor plants. It delivers water with 0 PPM dissolved solids or the equivalent of distilled water. It's made a notable difference in my ability to keep foliage pristine. Perhaps you know someone with an r/o system you can get water from.
