dude......haha that is a hard question with the pics you provided lol
....first pic..plant looks fantastic bro, well done
...second pic is trichs and shows LOTS of amber heads, which for some is the perfect time to harvest....third pic...I think that is the end of a brown pistil, some headless trichs and the rest are clear lol...clear trichs means its too early........the pics look like they are from trichs that are on leaves dude....try some that are on the actual flowers, it might give you a clearer idea bro:smiley1:
EDIT:....I think some trichs turn brown after we brush/damage them with our hands when we are growing.....not 100% on that tho lol!!!
