A fair while yet my friend I would say atleast 2-3 weeks if not longer though I do say it all depends on what kind of smoke you want personally I go for a harvest when not just the trikes are mature but there are enough of them and a plant will continue to produce trichomes alot in the last few weeks they are the most vital time for a plant :) She looks like a really healthy plant though besides the burnt edges hehe best of luck for a happy harvest bro
