some of my nep

[Angkau Tekor]

My first thought when i look at cway truncata is that the potting media might be too packed or it has got rootbound causing drainage and aeration problems. Since cway mentioned that he tried different caresheet to no avail, that's why i recommended repotting to bigger pot, hoping that it will solved his problem.

But now i'm a bit confused as sifu Nepnut mentioned that neps require little growing space for their roots in relation to the size of the plant. So what could be the reason cway's truncata is not doing well?
