So, it's day 50 since flip. The trichomes are increasingly turning milky and the smell is increasing and becoming sweeter. However, I have noticed a couple of new pistils appearing on the the top of the tallest buds, which leads me to believe it could be the start of foxtailing, so have lifted the lights back up to 18 inches as a preventative measure. That being said, there do appear to be some new pistils in lower buds as well. Oh well, better to be safe than sorry.
I wonder if the premature browning of the pistils could have been the result of the fan blasting across the canopy as I did have it set high when it was colder and the humidity higher.
The new scope I bought is not very easy to use and I struggle to even see the triches clearly with it, let alone photograph them. I did take some other pics, but the camera battery died so they'll have to wait for another time for me to upload them.
