Hey friend,
The grows looking great. I'd be wary of going off of the sugar leaves versus the buds though. I think you're getting very close to harvest but I'd personally let those clear ones get more in the 20% amount. Everyone has different opinions on white over amber, i usually like to let my ambers get around 25% because of the "less anxious" aspect. I think you maybe have a week to go before your windows open and then its just personal preference of how you like your buds.
Happy trimming.
Hello buddy, I'll tell you what I do, I only harvest when I see more than 70% of the trichomes are nice and dark...
Regards buddy, I hope I could help you
