Hi, your plant look for me as if they have at least3- 4 more weeks to flower. they just started with flowering. all the hairs are white and i cant see trichomes. .... if you want to know when harvest is near buy a jewelers glass (about 5 euro with light) and look onto the leaf and around if your trichomes get milky/ cloudy you will have about 2 more weeks. If they get from cloud to amber harvesting is near
