Until recently, I didn't know how different, apparently, Majestic Tresses are from most other Phrags. I just took for granted Phrags were pretty much the same. I'm sure I've been overwatering it while at the same time underwatering the others. I'm still not sure about how to use the fertalizer. It's liquid and OLD - about 4 years old. I'll be getting a new batch. You're all right about the roots. I took that photo of them when I re-potted (6 weeks ago) because they looked so different, almost black, from all the others. Short and thicker too. Would it be wise to change the M T mix, (adding perlite) and re-pot now, since I re-potted so recently?
As for the Living Fire with the seemingly verigating leaves, I've never used any sort of spray on or near it. The newest leaf dosen't have the white lines.
