She looks like she could use few more weeks bro. And as tokage said you should invest in a powerful magnifying glass or a jeweler`s eye, to view the trichs . Depending on what type of high you wish to have,.... clear starting to get milky = head high/ daytime. Milky is still nice for daytime. Milky and starting to turn amber here and there, heavier high, perf time !! Lil more amber almost all amber Perf !!! couch lock high. Wait too long and the trichs start to degrade.. Harvest in the morning at first light and bring to cool dark room. Best for outdoor I find. You may result with smaller rather then large kolas since your plant looks very sativa dom. Good luck n happy harvest !! . PS. good job on the supercropping (tying), a personal fav trick !
