It's no longer in that pot. It's in a one gallon plastic pot with like ten air holes in the bottom. The soil is an organic mixture with about 30% perlite mixed in and thouroughly broken up and mixed by hand, it's very loose at this point. If I blew at the pot hard enough soil would lift up and take off.

It can't be an over watering issue as if anything I under water it. It gets maybe two tablespoons of water applied directly around the bottom of the stem a night right before bedtime (dark cycle).
