| That is a natural phenomenon for some phalaenopsis, especially some pink varieties. In some, that "tinge" can be caused by too much sunlight-a reaction by the plant signaling it's reached its limit for light intensity. In Vandas, a tinge that color usually means magnesium deficiency. I'd review the phalaenopsis culture sheet, make sure you have it in the appropriate light and make sure that your fertilizer has appropriate micronutrients. |
