What to do in the weeks before harvest?

If your not using water soluble fertilizer just running clean water last 1-2 weeks would be fine

Don't start a flush until there are 95% brown pistils and harvest when there are 98-99% brown pistils. This will put you in the "10-30% amber trichome" zone without having to look too hard. At this stage she still needs good feeding to grow her flowers, so keep doing what you are doing for another few weeks. Hope this helps, Organoman.

Hey Buddy They need some feeding asap and an extra carboload. Dilute 2tbs molasses in 3 Liter PH Water + half dosage bloom nutrients and give it to her in the next watering. She needs atleast 2 more weeks. Good luck 🍀

I feel your plants still got some time, Your ripeness will be best determined by trichomes. Try and check them out on the buds vs the sugar leaves. Good Luck!
