Hey BiteAway,
They still need like 3 to 5 weeks.
Looking at your THC seeing crystal,more milky and some brown thc people think that they are done but looking at your
diary you still had a short flowering time. Don't worry about those brown trichomes, your plant will make new and more THC in the comming weeks :)
Your smaller plant looks ready but its because it got heat problems and probably also had dry soil. When this happens your plant stops flowering and is getting brown hairs.
Good luck growing :)
