@weedwhacker thanks for the feedback, it helps my peace of mind to know that they jades do lose leaves fairly regularly. It's a pretty hot window so maybe I'll try moving it during the day and see if that improves the spots. I'll look forward to hearing from

@purpleinopp it does have a drain hole at the bottom, I also added a layer of rocks and there is a plastic tray with holes too! Lots of drainage.
