Sudden Large Black Spots on Mature Catts

[realoldbeachbum]

Thanks everyone for the advice. I have hope now and will NOT trash them just yet.

When I entered the grow room this morning, there was Pot. Jessie Lee "Hawaii" with a big black spot!!! She has now been isolated, leaf removed, Phyton27 treatment, and cinnamon.

One other bit of information that I did not mention in the original email is: When I removed the affected growths, the cut was clean and bright green. No red circles or brown/black areas or oozing. Hopefully I cut far enough into good growth to avoid speading. We will see!

Thanks again, kind OB experts, you have probably saved my collection! ROBB
