Well, it's clear to me the UV (and lights in general) was far too bright. Don't follow AC infinity's instructions in the manual--1/2 their recommendations is appropriate. Probably cost me a bit in yield, but hey, I got some purple buds?? I'm new to growing these flowers; I'm happy to count it up to a learning experience.
Despite the incredible burn, I'm holding on to these for a bit longer while the lower buds finish ripening. Still plenty of clear trichs all around; minimal to no amber on calyxes yet. Honestly, I've been having a hell of a time identifying what is what. I have plenty of ways to look at them, from cheap loupes to full-on microscopes, but I feel I get a different result every time I look. It's all dependent on lighting and equipment so I'm going to stop placing significant stock in how they look. I have enough green fan leaves left to make it work for at least another week if I need to. Advice would be appreciated.
I went back and checked my photos. It's been about 8 weeks of flower since the actual buds appeared, 9+ since the 12/12 switch. I definitely messed up the schedule some but again, LEarNing.
Christmas update, 3 days later: pistil production seems all but finished on the plant on the left, but I'm still not happy with how the trichs are looking. Upper nugs are mostly cloudy, lowers are 50/50 clear, maybe less.
For the plant on the right, calyx production continues with vigor. Seems the plant is taking it's dying breath, but I want to give these new buds a chance to swell a bit and flesh out the colas. Trichs are *slightly* ahead of the other plant. I found a seed(?) but am not worried with widespread pollination with how the plants looked/this late.
Either way, keep on keeping on seems to be right the choice.
To note: Sorry about the hair in photos. I have cats, and despite not letting them near the grow space, their hair makes it in. I don't disturb the buds while growing but instead meticulously clean anything after hang/dry/trim. I find most of it just falls off after the plants lose their stick anyway.
