Looks like you have quite a few that can go into bigger pots. I usually pot up when the first two true leaves are well formed. Alex

Hi, William! Your plants look great! I think the pot size is fine for now, but, you can gently slip one or two out of its pot and get a look at the roots to see if they are growing down and around the soil, and holding it in. If they are, and they are starting to circle, it is time to move them to a pot that is at least few inches bigger in diameter. One pot size up. It is better to up-pot now, than in the winter if you can. You will have them under lights, but, will you be letting them go dormant during the winter?? Some folks don't like growing citrus in Clay pots (I started out with clay) because they dry out so fast, but, it depends on where you live, climate, and how often you plan on watering them. When you upsize, you could switch over to plastic pots, which are easier to monitor for water issues. And, they are lightweight .. I am sure you will get great advice from the pro's on here shortly. You are doing a great job so far!! Nice varieties! !

Yes, it could really use some water. Coming up soon when the lithops begins to split open and show the new forming leaves inside you will withhold water until it is done absorbing the outer leaves.

Where are you located? If you have a spot outside that gets morning to early afternoon sun I would put it outside. Gardenias do really well outside if you can find a spot that doesn’t get too much harsh afternoon sun. If you gardenia is doing well now and you’re not having to water everyday to keep it from drying out (a symptom of being very pot bound) I would wait until fall to repot after it has bloomed. Often growers will allow the gardenias to become very potbound to force a lot of buds for retail sale so it will most likely need to be at least potted up to a 10” container (not too much bigger). Where you’re located will dictate the timing. Lastly the black nursery pot will heat up too much if placed in full sun. If you can put it in a lighter colored pot it will help to keep the roots cooler, but make sure it drains or take it out before you water.
