Cymbidium bulb rot and yellowing leaves in Semi-Hydro.

[james mickelso]

I don't have an issue with S/H but this looks suspiciously like rot from being too wet. Not because it is in S/H but because it became and stayed too wet and unless it is dried out it will continue to rot. Once the bacteria invade they keep at it until the environment changes. Spraying with a bact/fungicide won't help now because the invasion has taken hold on the inside tissues. I've been wrong before but this looks exactly like the 20 or 30 I had rot on me when I started out. Too dense a mix and stayed too wet for too long.
