Day 64. Another week on the calendar! Time is flying but also feels like an eternity. Still can't tell if there is any signs of light stress from swapping to the QB this late in the grow. I do think the bag seed in veg sharing the tent is possibly showing signs of trouble (https://imgur.com/a/9Sn0gEZ) and would love if someone reading this could take a look and let me know. Other than that, nothing new today, won't water again until tomorrow maybe the day after. I've noticed the environment in my tent has become very consistent since swapping out the blurple. Not sure if it's connected but the RH has dropped to a steady 44% ish and the temp never climbs over 25. Loving it so far!
Day 64 update, my loupe and PPM meter arrived. Tested the run off and found it was over 2200 PPM. Flushed her with around 5L of pH'd water, got the run off to 1000. Leaving it there for now as it seems to be a recommended amount for late flower. Will probably only give her plain water for the rest of her time, maybe one more light feeding, then continue to flush it down in the next couple of weeks. Took some test shots with the loupe but sadly I don't think the magnification is strong enough to clearly identify the stages of individual trichomes. Maybe I can play around with it when I take her out of the tent again but that won't be for some time. Let's see how it goes!
Day 65. It's almost been 24 hours since the panic flush. She seems to be doing fine other than showing stronger signs of yellowing in the fan leaves. Not sure if its something to worry about or part of the end of life fade? Tried to get a few different trich shots from various flowers but again, the loupe is probably not strong enough to accurately tell. Wondering whether I should try to treat the yellowing or leave it.
Day 66. The yellowing continues but at this point there is probably not much to do about it. Gave her a small feeding PPM'd to 300 to see if it helps get her over the finishing line. Tried checking trichomes and can't really tell if some are cloudy or all still clear. Definitely no amber yet though. Hoping for a couple more weeks at most before the chop! She puts off different levels of smell day to day as well. Was a bit more pungent today, very nice smelling.
Day 67. She hasn't lost as much leaf as I was expecting considering the last few days progress. Trichomes still look a while away from turning and mostly looking clear. Still has lots of white pistils too. Humidity has been a bit higher than I'd like since watering but I try to keep good air movement and a negative pressure in the tent which will hopefully reduce risk of bud rot. Smelling good but wish she'd have covered herself with some more trichomes!
Day 68. All the yellowing/dying leaves have given up and fell off. Not worried as I think I have spotted the first signs of amber trichomes on the main cola and one other. Would love someone to take a look and let me know!
Day 69 (nice). Going along fine. The fading seems to have slowed a bit and haven't noticed it spreading to the remaining sugar leaves. Definitely going to give her another 7 days and assess then if she needs to be chopped. Thank you to everyone who replied to my question regarding that. As someone said, if I had already started flushing, the timing was perfect, and luckily I had already been flushing her, so I will continue to do so. I gave her a heavy watering today with some runoff and I might do once more before she finishes? She isn't the frostiest bitch out there but she's mine and she taught me a lot. Hopefully some of what I've learned with her will transition well to photoperiods and the bag seed that is vegging next to her. I'll flip her into flower once this girl is done.
Day 70. All her leaves are starting to fade now. There are still a lot of white pistils that concerns me about the timing. I feel like the plant will fade and yellow before it fully matures. The trichomes still look the same to me but I need to get better close ups really. She doesn't seem too frosty in recent days, not sure if it's in my head or not though. Still, hoping for a chop at the weekend if she finishes up, otherwise I might be forced to due to how fast she is fading. I think I also see some purpling on the leaves? Is that from the temps or from the nutrients being used up?
