I agree with you; i think its a watering/soil mix issue. The watering routine need to fit the media mix. You should repot your lil guy in some fresh mix(50/50 peat moss/perlite), and add water only a couple times a week. No standing water :-)soil is whatever it came in... looks like mostly sand and perhaps some kinda peat or coir. I add some water to the top to where it comes up to the leaves every few days.I'm going to let it dry out for a few days and see if it perks back up. I suspect some over watering issues.
