I just happened. One day I was doing canopy management and trimming leaves and noticed a sap-like substance oozing out. I thought it was interesting… and then checked again later and it was oozing out at many parts of the plant. Then I when I trimmed I found it all over.
This is the best picture I got of it, but maybe I’ll look in some of the buds and get more:
You can see it sticking to the end of my trim scissors.
