Hi!
Depends on how do you like to be high : despite the huge compression of you pictures (if you can, disable noise reduction) I can see you're around 65% creamy.
If you like the mental effect, you can harvest it in just one week. If you're looking for a more couchlocking stone, wait until you have a majority of golden trichomes.
By the way, if you have a [D]SLR or mirrorless camera, you can use the lens backward (pointing the mount toward your flower and looking by the front) and it'll act as an enhancer. 🕶️
