Why is my plant showing oranges hairs week 5 of flower ?

It’s actually week 4 I got that wrong,the thing is it’s only 1 top that is doing it that’s why I’m so confused 😩

She is just aging------- thats normal Singns of close to Harvest Plant is changing color to autumcolor// fading out Pistils are orange by 75 percent ( not all strains do it...........like gorilla its hard to say here if you look at pistils) and here we go... the trichomes...... Get a jewelers loupe // magnifier glass to look at trichomes,,, they should be all milky at least and from here on ( beeing milky) its just your Choice when to chop the ladies I let you alink here: https://www.growweedeasy.com/harvest#supplies-harvest

It sounds like the plant is already flowering so this is normal. Somewhere around week 4-6, midway through flowering, is when the first orange, red, and/or pink colors begin to emerge and proliferate. Hopefully, I answered your question and remember " Happy Growing and Free your mind one puff at a time ".
