I was told by the soil provider my plant is in that it is about time to harvest because the pistils have turned sufficiently. I want to double check with the experts on this forum. First grow and super apprehensive as well as super anxious.
Sorry you was told the wrong information. You have plenty of white pistils on her. The pistils will turn amber to dark brown then they recede into the flowers.
Glad you checked here first which is what you should do anyways. You have growers here with decades of experience. I used to pull based on what I thought was correct information about the pistils. Glad I learned better here from more experienced growers.
The fan leaves in the bud of my autoflower also served as an indication for me. Yours are starting to fade but I’d say you have a little longer. Do you have a magnifier/ jewelers loupe to check the trichomes.
Patience. You’ve got a few weeks(?). Forget the pistils and keep an eye on the trichomes. The starting of amber trichomes on the buds means she’s ready for harvest.
You certainly are getting close though. I wouldn’t be too harsh on the guy who told you these were ready (although it’s good you got a second …and third and sixth opinions) but some big commercial growers harvest way early because it can make for a prettier product.
