First grow - Auto Hindu Kush

Got a jeweler's loupe to inspect the trichomes but having a really hard time getting a steady image to tell what color they are. Some even look somewhat purple so not sure what to make of that. Day 79 - The leaves have become quite discolored very quickly. within about a day or two they look like the Day 79 pictures. Not sure if this is from the leaves naturally about to die off at the end of their flowering cycle, or a nutrient deficiency. The trichomes are cloudy with a small amount of amber ones thrown in here and there. I'd like to aim for more amber to try and get as much of that 'couchlock' feeling as possible, so I will at least give them another week. I gave them a super light feeding in case it was a nutrient problem, and ph'd water. This will probably be the last watering i give them, or if I push it to 2 weeks just flushing from now.
