Hey there! Don't worry, that is not mold, nor is it a pest problem. This phenomenon is called Guttation.
Itās essentially plant sap (mostly pure sugars and water) that the plant pushes out through its pores (hydathodes) when root pressure builds up overnight, or when the plant has an abundance of sugars produced during peak photosynthesis.
It is completely harmless! It actually looks super cool and almost clear/amber, like real honey. However, even though it looks sweet, it's mostly water and sugars, so it doesn't contain high amounts of THC/cannabinoids since those are produced inside the trichome heads, not in the plant sap. You can safely harvest and smoke your budājust let that little sap drop dry up or gently wipe it off if it bothers you. Congrats on the beautiful harvest!
