Some strains never go amber (White Widow as best example).
The brown spots: If you can pull those brown leaves out without any resistance, it's probably rot.
I would harvest it right now and save what I can, if I were you.
But I also don't want you to panic about it.
I have 0 experience... but I've read/watched a ton about it, during the last 3 months or so.
I might be wrong.
sorry to bring those bad news 😔
I should have checked the clear/milky/amber, I was so sure of myself! 😭
Yeah, I'll get it harvested...
The brown bits stayed put when I gave them a tug, cut the plant anyway.
Note to self do that sort of thing AFTER you go to the shops not before! 🤣
