I have switched to 12/12 about 7-8 weeks ago, I am using five CFL 2700 lights and the strain is Sativa. I used PHperfect Bloom, Micro, and Grow and just flushed it two days ago. The calyxes started swelling about a week ago. I do not have a microscope so I had to use my camera on macro setting to get the best zoom. Of course I still can't get a clear color of the trichomes. I'm hoping a pair of fresh eyes at help.determine whether it's time to harvest or if I should wait. Let me know if additional pics are needed.
