Is it harvest time? please help me

Pic 1, 2, 3, 8, and 11 trichomes tell a story. Still a majority of clear trichomes IMO. I'd go another week. water only. You want the trichomes to start to mature but perhaps the overfeeding is stalling the process. Older trichomes oxidized but the most resent not maturing fast..Not to fear though. If your plant still has legs and isn't dying and drying out dead, your patience will payoff. Most people look for mostly cloudy..often with a 10-20% amber and the bud will throw a few new clear trichomes daily.. If you can see mostly cloudy deeper in the bud then go for it but your pictures don't show nessesarily what your eyes will catch deeper inside. A majority of clear trichomes with cloudy gives most people a bit more racy high. Avoid if your prone to anxiety. Even with a strain known for a heavy stoned effect can come on racy if harvested to soon. Cloudy with some Amber will give a more balanced effect and a majority amber with that couch locked effects. Thc degrading at that point. In your pics the outside amber's are probably older or damaged oxidized trichomes, I really don't see many cloudy trichomes at all. Unless they're deeper in the bud. Don't use the sugar leaf trichs at all to determine when. I'll say this that your real close.
