I have an echeveria I purchased online about two months ago who appears to be spontaneously deteriorating. It looks like it’s been overwatered, however when it started dropping leaves it hadn’t been watered for 21 days and its soil and roots were bone dry. I figured why not try giving it some water and see what happens but even more leaves turned yellow-brown/translucent. I have it planted in a shallow pot (with drainage, under a grow light with three other echeverias who are all thriving minus some minor etoliation from back when I had the grow light too far away. Anyone know what’s going on here? Side note, all the leaves that have dropped have been on one side of the plant.
