Yellow droplets on your grow block
Small, clear to amber droplets on your block are normal. It is moisture that the mycelium releases during active growth; North Spore calls it natural and harmless. You do not need to do anything.

University of Florida / IFAS Extension · BS-01Droplets or bacteria?
Amber droplets are clear to pale yellow, odourless and do not change the substrate around them. Bacterial wet spots are cloudy grey, slimy and smell sour or rotten.

Nothing: it is a sign of active growth. If in doubt, smell it and look at the colour of the substrate around the droplets.
