I can't find the parent to this, so...

In my experience, most Milt and Mtps problems are due to water, one way
or another.

If the RH is too low or there is not enough water at the roots, the
leaves will accordian rather quickly.

Nearly all of the Milts I have bought have come in a fine bark mix.
With indoor growing, they need a lot of water to compensate for lower
RH. Fine bark + lots of water = dead roots. After moving mine to
semi-hydroponics (with coarse media), I give them a ton of water and
they grow like weeds. I suspect that sphagnum would work better than
fine bark for Milts, but I have not tried that.

FWIW, HTH, etc.
