It's not the pistils that you want to see turn brown, it's the heads of the small trichomes and you'd need a jeweler's loupe or magnifying glass for that. The pistils can turn brown long before the plant is ready to be harvested... And these ladies look like they've got a ways to go yet (4 weeks?) - I think you'll see them fattening up nicely. Just have patience - and use the time to buy yourself a jewelers loupe!
Good luck!
Hi there
The best way to tell if you’re ready to flush is to get a cheap jewellers loupe/magnifying glass and check your Trichome development,
when there cloudy and starting to turn amber .. flush 👍
Best of luck 🌱
Since you are using an organic fertilizer with Biobizz, it is not necessary to flush. In the last 7-14 days, you simply stop the fertilizer, and from then on, she only gets water.
