Hi @Bub1972. Take a look at this picture https://www.growweedeasy.com/wp-content/uploads/2010/05/when-to-harvest-cannabis-diagram.jpg

Hi @Bub1972! Pistils can be a clue, if you noticed that new pistils have stopped appearing and old pistils have almost all turned red and curly, but the best way to ensure it's the right time is to look at the trichomes with a magnifier/microscope. Clear/Transparent/Skinny trichomes mean it's too soon, Milky/Cloudy/Fat trichomes mean the harvest window is open, Amber trichomes mean the harvest window is ending, and THC is degrading. There are dozens of cheap hand-held microscopes available online or at your local growshop (5-15$). After months of hard work you don’t wanna rush this nor miss the best harvest window. Enjoy your harvest!

hey man looks like you're confusing pistils with trychomes. those little hairs turn brown, depends on the strain how they ripen, but when you cut your plant down they all turn brown anyway. Only way to really tell for the trykomes is to get a 70x magnifier, and you'll see them. When they rippen they turn milky / cloudy. You cant really see them even with 30x , i got a portable 70x microscope for 1.79 including delivery. Take a look, once the trykes have started to turn amber, they are oxidised and you're days away from the chop. make sure you check all up and down your plant to see how well they're doing, they can turn milky overnight ! hope this helps ! 🚀
