Is this mould?

Dear Gang,

Not really had anything worrying before, I had 10 grams in my last prescription with one nice big nug included!

One side looks fine but the other there is some white marks.

Please could the more seasoned among us tell me if this looks suspect or is maybe trip as im not sure!

All other nugs look good and all smells fruity. But the white is in the main body of the nug not on the trim etc.

Would really appreciate some views!

Cheers!

:)
