You have a jade, aka, crassula ovata. It is in desparate need of light. Was this where it was when you moved in? If so, do you have a balcony on which you could slowly acclamate it when the outside temps are above 55 or so consistently. If you just moved it to this spot and it is better-lit than where it was, these could be sunburn marks. Typically sunburn marks are more uniform in shape, though. It should have about 1/5 the amount of space it has between the leaves. It almost looks like it is supposed to be a Crosby's Compact which should have all the leaves very close together with proper lighting. Jade grows spindly when it isn't getting enough light. I would take it out of the plastic pot and repot it in a clay pot. Buy one that is shorter. THey are sold as azalea pots. Your soil should be very free draining. When I mix mine, I use one part pine bark fines or soil conditioner, one part grit (decomposing granite), one part high fired clay granules (turface, aquatic soil), and one part small pea gravel. When you water it, water should run almost right through it. If you use peat based soils, they will compact and stay too wet, thus strangling the plant due to lack of oxygen. Even the soils that say they are for Cacti and Succulents are too peaty. You could also try coir inplace of the pine bark fines or in addition to them in place of peat. Almost anything you would use for a bonsai would be okay for a jade since they are very free draining. They don't need a lot of fertilizer. Use something low in nitrogen. I use Schultz Cactus Fertilizer mixed for every watering, but I only give it to them every other watering during their growing season. It is warm where I live until Oct or Nov, which is usually when I stop feeding and slow down watering to once a month until it warms up again in spring. We were warming up in March and then had a frigid spell over Easter holiday. I've gone back and forth with my plants, but having a mild spring has been nice for a change. I hope this helps, and don't hesitate to ask more questions. Do searches on this forum about Jades, and you'll get more than you ever wanted to know about jades. They are, without a doubt, my favorite. I have about 10 different plants, 10 starts from cuttings and two that are bonsaied.

my cactus is suddenly leaning, and has some brown spots. These spots are not soft or mushy. It is located in the sun all day. what could be causing it to lean, and have spots? I do not water it on a regular basis.

I'm not finding photos of necrotic blight, but other blights show darker spots with a circular pattern not seen on my leaves. Also my fruit is unaffected. Septoria Leaf Spot sounds and looks similar to what mine have. Either way, the treatment is removal of affected leaves and a copper spray. I will do both as well as a preventative spray on my other tomatoes. Thanks, Omni.

What’s in the last two pics is normal or at least I see the same on my Opuntia. As Stush has said it’s corking. I believe it’s the beginning stages of corking. My Opuntia below has it all over the lower pads. What will happen is the circles will get bigger and then connect. Some of the dots are old wounds from being stabbed by other cactus. The top pic is the weird one. It possibly could be fungus. You could do one of three things, cut the little area out with a clean sharp knife, take the pad off, or leave it be and watch it because the cactus may just scab over. I would personally do the latter. I find Opuntia to be tougher than other cactus, just keep an eye on it and keep the cactus’ surrounding environment dry. Since it’s the cooler seasons your Opuntia should be kept dry, no water till Spring🙂. Edit: I thought of a fourth option, you could spray with a fungicide, but imo I would wait. As long as the environment is warm and dry the cactus should heal the wound. It will always have a scab in that area tho.
