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.
