At what point the buds start to frost ?

This whole grow is 100% organic no nutrients everything‘s been homemade I’m asking because I’m on my second week of flowers and took a couple pictures up-close and notice my buds frosty in 2 weeks of flowers ? It’s that right? It’s a 10 weeks flowering time for this plant

Yeah seems normal. That’s when my trainwreck started to get frosty.

Nothing out of the ordinary

Good to know it’s normal but what those purple hairs in the buds mean what it’s happening to the plant right now for when I see this hairs again what it’s the plant doing at this point ? It’s what I’m asking

Pheno expression.
