Trichomes Aren't Turning Amber

hey guys it seems like my trichomes are never going to turn amber. its been weeks since i thought my plant was done im always checking the trichs and they arent amber at all. also my plant is on the verge of being dead i fried it with a 600 watt light with no ventilation and some branches are literraly hanging on by a thread so im wondering if theres not enough energy in the plant for the trichs to change color maybe? heres a pic of my plant should i wait it out or harvest

hps lighting makes it hard to tell from pics. how many weeks in flower?

not exactly sure but i know its been much longer than enough. plant should have been done in 45-50 days after flower
