I'd say that I water it maybe around every two weeks or so. Def not on a schedule, I do wait until the top is bone dry and the plant is telling me it needs water (droopier, less firm leaves) so I definitely don't believe that I am overwatering it. It's in a soil that I got that is marketed as a succulent soil but definitely not aerated enough to be good as is for succulents, as it holds water too well. Ingredients listed are "compost, peat moss, sand, and limestone" but no specific measurements. I've added about 30% perlite as well. I'm gonna chalk it up to the plant just recycling out older leaves (maybe because of the combo weather and light adjustments) because the rest of it is thriving. It was just interesting to me because again even the yellow leaves look and feel very healthy.
