so questions about portulacaria afra. I was looking for indoor bonsai and had some portulacaria afra in succulent arrangements so chose that one. See photo attached. All leaves are turning black and dropping off. I am watering every 3-4 days as soil dries out and happening with both soil types using 1.) bonsai soil mix (pumice , lava, calcined clay and pine bark) 2.) cactus mix with extra perlite. Both are having same issue. Plants are around 24” from grow light and get around 7 hours a day. Humidity around 50%. All other plants are doing fine (succulents, money trees, etc). However this one just can’t get right. Any suggestions on soil type, watering schedule or any tips would be greatly appreciated.
