I don’t know when should harvest this plant. What do you think?

Strain is unknown.
Nearly all pistils are dark, but trichomes don’t tell me much (first grow, can’t really differenciate yet clear from cloudy). Buds have grown a little during last week, but definitely not too much. She was kept outside and first actual but tiny flowers appeared around 20-25th of August, pre-flowers around 10-15th of August.

100% legally grown for own consumation

Thank you
