Bletia leaf tip die-back

[Herrania]

I acquired a Bletia patula 5 days ago, it came bare root and I noticed some of the leaf tips were dead. Since potting it (pro-mix HP, stalite, marble chips) next to a humidifier, the die back has moved down the leaves. Does anyone know if this would be expected from the stress of shipping and potting, or could this be something more serious?

Edit: I sprayed it down with neem oil when it arrived, have I found one of the few that hate the stuff?
