Symptoms NOT caused by virus

Symptoms that are NOT caused by virus or for which tests were negative for CMV (Cymbidium Mosaic Virus) and ORSV (Odontoglossum Ring Spot Virus). Some plants were also tested for BYMV (Bean Yellow Mosaic Virus), but this is an uncommon virus in non-pleurothalids. Any additional info on these symptoms would be appreciated.
