I'm 6 weeks into flower on my first grow and trying to plan my harvest. I've read all the amazing stickies regarding when to harvest, and will be watching trichomes as well as the other signs of peak ripeness that SpruceZeus mentions in his sticky. I just picked up a 30-50x handheld scope today and I'm going to have a look at all my plants tonight as soon as the lights come on.
I am under 600W HPS, in Promix, using GH Maxibloom and Koolbloom (liquid and dry) in a modified Lucas grow, and I'm growing Nirvana White Widow and Northern Lights. I am planning on doing a 2 week flush with straight RO water, but I have no idea how my plants/trich's will look in 2 weeks! The color of the hairs vary greatly from plant to plant (some plants are 100% white still, some are 75% red already), so I'm ignoring them altogether and want to plan my flush based on what the trichomes tell me tonight.
I haven't found much helpful information on judging when the START flushing based on trichomes. I know it will vary according to strain and environement, but how long does it take a trichome to go from milky to amber in color? Will they stay milky for weeks or do they progress quickly? If I wanted to harvest at say, 10% amber and 90% cloudy, would I start my 2 week flush at the first sign of cloudy trichs, or later when the trichs are all cloudy?
If any experienced growers could shed some light on these questions, I'd greatly appreciate it and will toss around the +rep like confetti!
