looks like it to me.
if you have a scope what are the trics like, day count etc how long left to go?
i think i would chop off the section myself or harvest if near done. i found mold in the main cola of a plant i just harvested, it was travelling down the stem in the centre of the bud but i couldnt see anything from the outside. best to stop it before its everywhere. see what others think though.
separate the moldy bits soon as you can if you harvest dont dry them with the rest if you keep them atall.
*from what i hear ice hash is not mold safe, neither are edibles. bho and other solvent based ones should be.
