Default reddening of dendrobe pseudobulbs & foliage

Hey Kenni,

How does a magnesium deficiency show its ugly face? Does it come on fast?
We use a lot of Cal-Mag fertilizer here and I do not think I have ever seen
it.

From sunny south Florida -- are you sure you have a problem at all?

Around
here, we consider a bit of pigment showing in the foliage to be a "healthy
suntan." I have one client who was keeping her [one live] den with her
phals, and then complaining that they never bloomed ... I moved it out

into
brighter light, it started showing some red-purple in the foliage, and
promptly put on an incredible growth spurt.

The most common nutrient deficiency that we see is magnesium, and applying

a
bit extra [preferably chelated, but in a pinch Epsom Salts will do] will
help to green up both pale and reddened foliage.

Good growing,

Thanks for your response, Ray.
After checking out "Plant Nutrition" on your website, I assume my
problem may be low phosphorus?
If so, will a higher P fertiliser reverse the colouration, or only
improve it for new growth?
