Hi all,
I would appreciate some input on what might have affected some of my Cattleya plants. I have something that attacks the new growths, starting with a small black sunken spot or brownish tinge on the new growth. This spreads until the whole leaf tip is black and then the whole leaf might die if severe enough. Sometimes it stops when half of the leaf is black. I have difficulties deciding on what it can be. I am considering Pseudomonas (Bacterial Brown Spot - Acidovorax), but then the older leaves should be affected as well. The other thing I am thinking of is false spider mites. However, I do not see any mites even with a x15 lens. Can they be too small to detect even with this magnification?
