...
Several of my dendrobes (moschatum, phalaenopsis hybrid, pierardii)
are showing noticeable reddening of pseudobulbs & foliage.
I believe this is typically due either to too much sun or to a
nutrient deficiency. In this case I doubt sun is a problem.

I have read an explanation of the nutrient deficiency - can't remember
where, or what the cause was.

Can anyone advise, & if possible point me at an on-line elaboration on
the problem please.
