I actually haven't watered for about a month or possibly more. The soil just looks wet because I gave them a good soaking. I clipped all the old shriveled leaves off the bottom of this plant. I'm wondering if I'm underwatering for this plant. I'm not 100% sure, but this is the only one that looks like it's dying now. I'm using a succulent/cactus soil I bought at a gardening store. So the third photo is right after repotting. So it's drastically changed. This specific plant is in my living room tv stand right next to the sliding door. It gets indirect light for 8+ hours. I also have 4 other plants in the same room that aren't wilting away....Do you think the Miracle Gro succulent plant food pump stuff is killing it? I used it two waterings in a row to try to see if it helped, but nope. All the other plants receive the same treatment, but they don't look like they're dying away..
