Hello @mipiano, nice to greet you, good that you like plants, plants give life to the spaces of the house, on my farm I have many, but even so, I also grow them on my balcony, especially aromatic plants. Your plants look very good, you say that one of them looks a bit withered, good friend, succulents have their water reserves in their leaves and stems, they can spend 7 days without watering them, I recommend you supply them with more substrate, preferably compost, for the nitrogen contribution, greetings.
