How does this bud look?

Hi I was just looking g at a bud I snipped from a plant to see how close I am. I noticed some dark spots on this bud and am not sure what it is. I need a trained eye to see what's going on and also how close to harvest time as well. Ty

Iv had this time an time again if its only one section of a bud still on the plant snip it out. Iv had a few leaves that died and curled up into my buds causing that section of the bud to go brown. Hope this helps somewhat or relates to what your talking about
