Mold?

First grow - Durban poison sativa
About 7 weeks into 10 week flower cycle

Started noticing this white spot at the top of a couple of the buds. Might be hard to see but tried to capture it.

Does it look like mold? I don’t notice any different smell - still smells sweet

Anything I can do to save the rest of the plant if it is mold?

Everyone is going to want to know the relative humidity and air flow you have in the tent.

Sorry - humidity is low - 25%
Airflow is 2 small fans built into the cabinet. They’re higher than the low buds, so I’d say airflow is lower than I’d like

Almost looks like light bleaching what's the lighting situation?
