I am having a serious problem with my collection of Phalaenopsis Orchids. They have what appears to be a type of Orchid Rot that starts with the roots and moves to the core of the plant after which the leaves start to turn go & the plant then dies. I am at a loss to pin point this problem, as I cannot find any classic disease signs before it’s too late. I am treating the plants with a topical fungacide and bactericide but it seems to be ineffective. It spread like wildfire killing 6 plants in the space of a week before I separated the plants to their own discrete areas and since then another 2 have died. I have ruled out the basics (water humidity temp etc) changed the mix sterilized everything but so far nothing seems to slow this pest down. Any advice is appreciated, as I am desperate so save at least one or two. Photos will be posted
