"Unknown soil" is not good . If it was me I'd yank that bitch out of the pot you've got it in, then replant into a 6 " pot with a known media like Promix or Coco Loco. Add mycorrhizae and an organic fert like 6-4-4 when transplanting. Water thoroughly and use a suitable light source!!! Peace... Have you done a soil saturate test on the unknown soil ?
