Wow nice pics and nice buds man. You got a perfect look on ur trychomes, just cut it on the moment u like, depending on what efect you looking for. 30% amber 70% milki ..."is the way"hehe 🌌
I wouldnt give them any water in the last 3 days or so, making sure the soil is dry.
About the dark period, is there any solid evidence? Just care with the humidity if u do it, to prevent fungus.
