Good looking, trichome dense buds you have there. Good job.
What you want are the milky trichomes so wait till you have at least 20% amber trichomes and harvest. In your case you don't have any yet, and some trichomes are still transparent.
The more amber trichomes you have the more relaxed effect you will have (but I wouldn't go higher than 40% amber). Rough estimate you have about 2 weeks left
