She is at week 13, she looks like one that need to...

If the trichomes are part amber and cloudy then that's one good sign saying its ready. some clear is also good. I'd also look at the pistils and how they look. If a bunch of them are dried up like 70-80% its also a good indactor to harvest. A proper dry+cure is just an important as the grow, remember to burp jars or use a system that works for yea. Good Luck!
