    Default Paph concolor

    Dear All
    My Paph is growing a new fan and it looks healthy except for that dark leave.
    I read it likes a subtract with a PH 6,5 to 7,5 and to achieve that is recommended to use crushed shell when potting it. (I did not do that).
    I give it MSU fertiliser and CalMag and flush it every 3to 4 weeks. Light is bright but no sun, and temp 22to 24 degrees C.
    What can be the reason for the unsightly dark leave? it is not mushy or limp, only dark !
    Please give me dome guidance here.

    May I say that I also recently bought a concolor. I think it is doing very well. And it doesn't look any better than yours.

    Hi Zain
    You were right to be concerned. Today the infection had spread to the opposite side leave from the base to the middle (so it has to be bacterial infection.)
    I did remove the affected fan (had excellent root system, no dead roots).
    The other fan and the new growth seem to be ok, nevertheless I did spray them with Physan20 before repotting.
    Thank you for your support.
