1st time grow Brazil Amazonia organ LED

I don't know anything about the right time to harvest. Although i researched and inspected the trichomes, it's hard to tell if they are ready yet. I found that maybe less than 5% of the trichomes have brown spots but in my point of view in general they don't really look that milky. Also had to fight with humidity, especially 3-4 days after watering (61-67%). I stopped to give them nutes and I'm planing to harvest next sunday. If anyone could tell me if they are ready to harvest, I would really appreciate a comment :) Cheers and happy growing
