Drying my plants temperature are 67-75 humidity is like 40-55. One bud has a wierd discoloration kinda a brown color or something. Sent from my iPhone using Grasscity Forum
I can usually tell by fluffing it up by my nose, I either instantly get a headache or start sneezing. Might work for you, lol.
Looks like nute burn/light burn that went into the bud. And judging by your fan and sugar leaves id say I'm right. The yellow/brown bud is just dead plant matter at this point. Just cut it out, no biggie. Or grind it with the rest and smoke
