Alright...sap it is. I finally found pics of someone else's on the net...NEVER seen it before on the bud itself, at least not that I've noticed.

aloha Reviewed by aloha on . sticky amber balls....what pest? My last harvest ended up with a few areas that had sticky little balls, like honey or amber, on the buds. Very sticky. It only affected one of 2 strains I was growing side by side...and as far as I can tell it reduced bud size, but the plants were still harvestable and loaded with crystal, etc. Growing Indoor in beds, Sunshine #4, Advanced Nutrients, temps in the 70's, good air flow, Ph always between 6.1 and 6.3. Both strains/cuts came from the club...the problem was on some Cherry Kush Rating: 5
