When To start flush? (New Grower, all advice needed and appreciated)

Hey! Harvest window opens when you start getting amber pistils. Normally when there's 70% amber and 30% white pistils they're ready but that's not always the case. The best way to check is looking at the trichomes. Clear trichomes haven't reached their full potencial yet, cloudy ones are full of THC and amber are losing THC while gaining CBN. So depending on your preference whether you want more of a head high or body high. I harvest when after examining and finding 70% cloudy trichomes and 30% amber trichomes. For me that's a prefect combination, depending on the strain as well. Have in mind if you use nutrients you'll need to flush the roots, watering with PHed water only for at least a week before harvesting. That way you'll clean the roots correctly from all the nutrients used.. As for the difference between CLOUDY or CLEAR.. Clear trichomes look like shiny glass while cloudy ones look like more like plastic. Good luck and Happy Growing!😃🌱🌿🌲
