It could be oedema, which happens as a result of too much water.

Would you recommend repotting or just watering less from here on out? Thank you so much!

That depends on soil it is in. If water retaining (that I would suspect it is since you said you water once a week and it should dry up enough in Summers heat), it should be repotted. All my jades are in very gritty mix and stay outdoors, being rained on a lot - sometimes 3,4x/week. Drainage is excellent and there is no problem.

Your plant also needs more light, it shows etiolation. Where is it kept?

Thank you for your advice! I inherited the jade as a gift and am not quite sure what soil it is potted in.. it does stay moist for a few days after watering so I'm inclined to get different soil.

I have a spider plant and then a variety of succulents/cacti (see pictures/labels below). Most of the small succulents are just potted in their original soil from Home Depot. All of the pots are draining and I water the succulents 1x/week. I appreciate any advice that you have! Thank you so much.

One more (the flowers are droopy on this one and the new buds are drying up)

All of them need better light.

They usually come potted in peat, and that is difficult to keep just right as for moisture. Watering them 1/week could be too much, or if peat dried up completely, not enough: but do not start watering more often since dry peat is hydrophobic and repels water. It would be best for your plants to be repotted into mix of Cactus&Succulents soil mixed minimum 50/50 with sifted perlite. And all of them in better light (not sure about peperomia, I never grew any).

Cactus in 3rd photo has a fake flower glued o top. You can leave it or remove...

White plant is Senecio haworthii.

Next a Kalanchoe, I believe milotii.

Is the next one in glass jar? Any drainage holes? It may be Crassula perforata(etiolated).

Last one is also Kalanchoe, K. blossfeldiana and it may be overwatered.
