I put in the dark for 2 days then started 12/12 on Aug 19 should it be budding better or does it look fine

Looks a bit hungry for nitrogen otherwise it looks good.

Looks good and that thing is gonna stretch big time. I’d start training asap if you don’t have a lot of height

The red stems indicate that the plant is lacking nitrogen. If enough nitrogen has been given, it could be that the pH value is incorrect and the plant cannot absorb it. That’s what I would think about first. Furthermore, I wonder what the two days of darkness are good for; in nature, this also doesn’t happen to bring the plant to flower. A normal reduction in lighting duration would have been sufficient. After all, the plant needs light for photosynthesis, from which it draws its energy to grow and thrive. So I would test the pH, and if everything is in order, slowly reduce nitrogen and increase phosphorus and potassium instead.

Red stems are not a sign a plant needs nitrogen. Pale yellow lower leaves is nitrogen.

My mistake, phosphorus deficiency would have been the correct one for red stems and stalks.

Red stems are also a sign of low temperature. It’s the anthocians (I think I spelled that wrong). That is basically like the plants antifreeze. It helps prevent cell damage due to low temps. All my winter grows get it as temps fall into the mid 60s (Fahrenheit).

Seventeen days after flip I would have expected the beginnings of visible flowering, but some strains have longer phases than others. Do you see any pistils at all? Give her time, she’ll start showing.
Incidentally, I’ve never heard of killing the lights for two days before flipping, I just flip. Have you always done that?

Yeah but again I’m new to grows

Hey, that’s cool, you gotta start somewhere! May I ask where you got the idea for two days dark before flip? I’d love to know more about the idea behind it.
By the way, any changes, showing flowering?

IMO the 2 days of darkness should force the plant to start flowering quicker than normal. It’s similar to the 2 days of darkness at harvest but at the beginning of flower instead. I used to do it but honestly, I didn’t see much difference.

A period of darkness before harvest has been proven to be nothing but bro science

Interesting, I’ve never heard of doing that, but I’m always learning new things. A few times I’ve switched to 15/9 for a few days before 12/12, to briefly imitate nature’s gradually shorter days, but like you I couldn’t see any difference. I suspect there is a sweet spot light/dark ratio that triggers flowering, so I can’t see the point in imitating that part of nature.
Seems to me that depriving plants of light would interrupt its processes, maybe cause stress. I only do that on harvest day.

I found that a 14/10 cycle will initiate flowering better. A fair amount of cultivars will start flowering at 14-14.5 hours of light. I do an 18/6 in veg then 14/10 for 2 weeks then 12/12 to finish. You could also do a 10/14 cycle the last 2-3 weeks of flower. It could help with heat and possibly put them in overdrive to finish.

I agree that it’s bro science. I was using it as an analogy. It’s amazing how many people still swear by it. I watched the video where Dr. Bruce Bugbee talks about darkness before harvest. He has a ton of knowledge about growing. Too bad he grows hemp and not actual weed. So there is a chance his data could be different from someone growing smokable cannabis.

Good info, thanks. I wonder how much difference two more hours of light would make to its growth if I left it at 14/10 throughout flowering.
I wish my lights were the source of the heat, I could control that, but those LEDs don’t get hot, just very warm. The summer heat and humidity getting into my uninsulated gambrel shed do that.

You can use the lst clips or a trellis net (can find both on Amazon) to force the growth to spread out more evenly instead of straight up into the light. Here’s how I did mine with a trellis net that’s like $10 on amazon

Idk I’ve never tried it past week 2 of flower. You could try that but it’s cheaper to run a 12/12 cycle and you get guaranteed flowering. I think a 13/11 cycle would work in this scenario also. You get the extra light and just about guaranteed flowering.
