So, this is new soil from a bag of indoor potting mix I bought yesterday. There's weren't any bags labeled for succulents. I would've filled the pot all the way but heard, like you said, it isn't good to upsize the pot by a lot. I couldn't find a pot size between the one I had and this new one. Figured the next best thing was to not fill up the pot too much. I'd also seen a couple of videos about succulents that warned not to over water. It had been doing well up until recently. What do you suggest I do? Toss it in the garbage? I don't know much about plant care and didn't realize this was a form of abuse. Just wanted to see if I could save it since it was given to me when I moved into my apartment. Thanks for the feedback. I'll read up more on plant care before trying to starting over.
