Abnormal crystalline formation on buds

[NMPaulie]

Honey banana grown in a pot, indoors and out. Moved from morning sun on back porch to afternoon sun in front window. Healthy. Most colas turned out great. Some later developed buds show this. Grown in soil with recommended liquid nutes.

ETA: Hi everybody! Noob grower.

I'm going to pretend those are my plants and consider beard dandruff. Since I don't know your facial hair situation, I'll suggest something got dusted on, knocked on, brushed on, or thrown on your plants. I say that partially because you seem to have knocked off all the trichomes. Also, because those bits are inside your loupe. Maybe moving inside and out got something on them?
Can you post non-louped bud shots.

Perhaps the residual from nutes after evaporation. Salts?

Have you been spraying them with a foliar spray or accidentally tipped the nute mix onto them?

Upon further review, it may be gypsum...
White Sands occasionally likes to visit up the hill a bit.

Odd though, in that this is the only plant with the stuff on it.

Looks like white asbestos to me.

look UP above the plant if inside.

You get aerated gypsum particles. I get aerated fecal matter and medical waste.
