7/27/19 - removed microfiber towels due to feeling that roots weren't drying out as they should. presence of white mold. Just a few days after, bottom three leaves started to yellow. Possible causes are excessive drying/under-watering of roots or possibly caused by the mold itself which has dried and cleared up. Will keep an eye on plant and care for it while it recovers. Will try potting in clay pellets for a couple months to promote new root growth. will add kelpmax.
