Make sure you are not checking the trichomes under a HPS light. You won't be able to see the amber trichs as easily.
Always use fluoro's or MH to check trichs.

Otherwise, just be patient. They WILL eventually change.

Hi Guys, Believe it or not I'm on day 86 (week 13) of flowering with a couple of Great white Sharks and I'm waiting for the trics to brown but they seemed to have stopped or slowed done considerably. Should I harvest now with most of the trics cloudy or give it a bit longer. The plants are dying off with most of the leaves turning yellow, which I know is normal for this period. I think I messed up somewhere along the line with my Ph and didn't get it sorted until quite late in the grow, I Rating: 5
