I decided to go with water-only feedings this week. I'll check her trichomes next Saturday, or the end of NEXT week, Day 75 and we'll see if I should continue to flush or pull her then. If she's not ready, I'll check trichomes weekly until she's where I want her. I do believe the harvest window is open now, but I want to give her more time to mature.
Feel free to comment if you think she needs to go more than a week or two after this week ends. I'd hate to take her down too early. The Galaxy Brain in the same tent looks about 2 weeks away from where this plant is. Last grow, I think I made the mistake of pulling both plants at the same time when one was clearly not ready. It was done mostly due to not having space to dry, but now I have a 4x4 being delivered and can separate the plants.
She's looking MIGHTY frosty, super dense in some places, and I'm hoping to get 80g or more from her. Only downside is that she's about 1/3 the height of my previous grow, so I'm probably overestimating what I'm going to get. I picked up some Grove Bags for the cure since I'm not comfortable using humidity packs (they always mistreat the flower in my experience). The Grove bags are engineered to keep your flower at 58%-62% humidity and not require burping, so we'll see how well it does. I figure it can only help by dummy-proofing the curing process. The idea, as far as I know, is to take your dried flower, fill the bag, and seal. The bag does the rest (when it comes to the cure). First time trying it, so we'll see how it goes. If anyone has experience and DOES NOT recommend it, let me know ASAP before I mess up my whole harvest :D
