Are purple root tips normal?

[Gage]

Agreed, normal for many, but not all orchids. Technically the foliage and root tips of orchids turning red-tinged in higher light is indicative of a magnesium deficiency. I'm not sure how ill-affected by magnesium deficiency a plant showing these signs would be. But many people use this sign to help determine when the plant is getting sufficient light, and it seems to work. It is the plant saying of its current light, "Thus far and no more.".

I have an encyclia that suddenly developed a strange looking marbled purple pattern when I brought it outside for the summer. Magnesium maybe? As far as purple roots go, I have seen them on perfectly healthy plants.Posted via Mobile Device
