Hello. Well, I have a problem with N. Rafflesian's pot. Previously it was the same with N.reinwardtiana and he died. It appears that the leaves turn yellow> curl> brown. The cone of growth changed color and it was very windy, so I honored it. The rest of the cone changes color, the one in the middle looks ok but it probably starts to deteriorate. Watering every 2-3 days Conditions on the southern parapet, 19-25 C humidity 30-50%. Subsoil peat, perlite, sponge, dead moss. What could be the reason ? I exclude pests.I suspect over watering but i dont know.
