Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

Things have been going well as I continued to train the stretching girls to the side of the pots, bending and adding ties where needed. Pheno 1 started showing signs of over watering showing droopy leaves as well as what I think is either nitrogen, magnesium or iron deficiency. I'm leaning towards a iron deficiency since the yellowing is on the newest growth at the top. I think this was caused from giving her too much top amendments in her last feed causing a pH imbalance. What I would usually do is just give her a little flush if this is the case but instead I decided to repot her and the other Pheno into their last 19 litre/4 gallong pots as both were drinking pretty quick and I wanted to avoid over watering again. The rootballs looked beautiful when I transplanted them so I was pretty happy with their progress! This round I've ditched the coco as I had way too many issues with it in the past, including knats and PH issues. In this round I've gone with Biobizz light soil which I added some fish blood and bone, earthworm castings, bat guano and then watered with water and liquid seaweed. I love organic growing :). I do intend on using Coco again but I'll need to do some research on some trusted brands. If anyone has any suggestions please let me know! Pheno 2 is showing signs of recovery but I'd love the input from others about what the deficiency could be? I got my new bubblebags today which is making me want to flip to flower so I can get to harvesting and making some bubble but I'm going to be super patient this round. I want these girls to fill up as much of my 4 x4 tent space as possible. Until next week! ✌️

Probably looking at next week for a tentative flush and harvest. Some leaves starting to yellow from maturation, and pistils are getting to where they need to be, with some new white ones still being thrown up on both plants. The smell is strong and exquisite, pungent and sweet. Resin production also looks to be coming along nicely, covering leaves alongside frosty trichomes. Quite a few buds and whole branches have that snow covered look that can’t be beat. Won’t be able to hand water this week so leaving it to the auto waterer with reduced nute concentration. Cheers

Hows my purple queen looking?

And Another one, underestimated the stretch on the Mintz she can’t complain she ain’t getting light lol.

Second time flushing it.. I’m also running out of time before harvest I should’ve been flushing it a week earlier.. she’ll be ready in 2 days for chop

Everything bounced back to normal. These smoothies want a bit of nitrogen throughout veg. 90% of the time when I have an issue it’s because PH or PPM being too high. This wasn’t the case as I ran two tests on my medium and everything was fine. Once i fed them twice with some higher nitrogen levels and some kelp n algae they bounced back in a week. After the first feeding I could notice a nice green coming back into the leaves. I have not flushed once since then. I’ve been feeding a tea every two weeks instead to break up whatever’s left behind. I plan to do one more feed in a couple days and I’m gonna do a light flush with SLF and then continue feeding nutes and teas until she’s ready to be flushed towards harvest.

Started to have problems with insects munching on the leaves, I applied trifecta and insecticidal soap simultaneously so they do not get used to one or the other and it has seemed to stop their destruction for now. Will continue to apply one a week as a preventative measure. Have not given the plants any nutrients up to this point since they have not shown any problems during growth

I've turned the light up to 35000 lux. Up'd the bloom to 1.5ml/l. There still stretching and could do with more room but there doing well 😎

week 9 day 58, the buds getting bigger, nice colors 😍🌈 day 61, she's look great and healthy! the trichome started to become milky.. still no amber trichomes are showing..

Raised up the nutrient level . Dealing with colder temps at the moment.Added a 75w cfl to keep temps up. Noticed the lower leaves are starting to lighten up. I fed them and will watch to see if they bounce back. I will up pot during this week for sure.The young ones looked very sad the last couple of days so I up potted. Once the transplant shock is over for them I will lower my ph from 6 to 5.5. and see if that helps with the yellowing of the leaf edges. I have been watering once a day with the nutes at 5.5 ph after transplant. I ordered a humidifier so I can keep that under better control as it stays way to low for my liking at the moment. The plants look happier 2 days after transplant. I do see signs of some deficiency on older growth.

So here we are! Time flies… they had quite the stretch after flip I flipped about a week ago, and they’re continuing to stretch and fill out. Defoliated the bottom a bit where no lights is reaching. Girls are happy so far, the OG that was straggling behind is also catching up even outgrowing the other OG. A little discolouration, however I’m not using nutes just guanakalong earth let’s see if it will be enough until end of flower… didn’t have quite enough earth so pots are full full but I hope good enough…

Week 3 of flowering has started! More defoliation and loolipoping is going on and is passing the surface of the SOG... buds keep fattening, although this light is very poor I think inhave mentioned that before!!

Beautiful pheno of Ak420 by seedstockers same smell as her sister, the other 2 plants of this same ak420 package, let's see how this wonderful lady keeps developing, I think I could have train this lady just like this but I should have gave her a few more weeks of growth before changing the light cycle.

All is good!

End of the first week flush, definitely looking like a 63-70 day finisher. One pheno is putting on quite rediculous weight for the size pot. Smell is quite a mix of California orange and gdp and a visible size increase due to the bilbo. Looking forward to see how this one turns out

Update in the video😁.
