Finally the buds are starting to take shape and actually look like buds ! The temps have been hot but I keep the lights of during the daytime from 11am to 11pm to avoid the hottest hours Defoliate as it was essential to avoid moisture buildup. Other then that the plant stopped stretching and it’s growing buds from now on O super frosty all ready the phone cam dose no justice!

Hello Growers, I really didn’t do anything this week but gave it PH’d water let them grow.

ANTHOCYANIN production is primarily controlled by the Cryptochrome (CR1) Photoreceptor ( !! UV and Blue Spectrums are primary drivers in the production of the pigment that replaces chlorophyll, isn't that awesome! 1. Diverse photoreceptors in plants Many civilizations, including the sun god of ancient Egypt, thought that the blessings of sunlight were the source of life. In fact, the survival of all life, including humans, is supported by the photosynthesis of plants that capture solar energy. Plants that perform photosynthesis have no means of transportation except for some algae. Therefore, it is necessary to monitor various changes in the external environment and respond appropriately to the place to survive. Among various environmental information, light is especially important information for plants that perform photosynthesis. In the process of evolution, plants acquired phytochrome, which mainly receives light in the red light region, and multiple blue light receptors, including his hytropin and phototropin, in order to sense the light environment. .. In addition to these, an ultraviolet light receptor named UVR8 was recently discovered. The latest image of the molecular structure and function of these various plant photoreceptors (Fig. 1), focusing on phytochrome and phototropin. Figure 1 Ultraviolet-visible absorption spectra of phytochrome, cryptochrome, phototropin, and UVR8. The dashed line represents each bioactive absorption spectrum. 2. Phytochrome; red-far red photoreversible molecular switch What is phytochrome? Phytochrome is a photochromic photoreceptor, and has two absorption types, a red light absorption type Pr (absorption maximum wavelength of about 665 nm) and a far-red light absorption type Pfr (730 nm). Reversible light conversion between the two by red light and far-red light, respectively(Fig. 1A, solid line and broken line). In general, Pfr is the active form that causes a physiological response. With some exceptions, phytochrome can be said to function as a photoreversible molecular switch. The background of the discovery is as follows. There are some types of plants that require light for germination (light seed germination). From that study, it was found that germination was induced by red light, the effect was inhibited by subsequent far-red light irradiation, and this could be repeated, and the existence of photoreceptors that reversibly photoconvert was predicted. In 1959, its existence was confirmed by the absorption spectrum measurement of the yellow sprout tissue, and it was named phytochrome. Why does the plant have a sensor to distinguish between such red light and far-red light? There is no big difference between the red and far-red light regions in the open-field spectrum of sunlight, but the proportion of red light is greatly reduced due to the absorption of chloroplasts in the shade of plants. Similar changes in light quality occur in the evening sunlight. Plants perceive this difference in light quality as the ratio of Pr and Pfr, recognize the light environment, and respond to it. Subsequent studies have revealed that it is responsible for various photomorphogenic reactions such as photoperiodic flowering induction, shade repellent, and deyellowing (greening). Furthermore, with the introduction of the model plant Arabidopsis thaliana (At) and the development of molecular biological analysis methods, research has progressed dramatically, and his five types of phytochromes (phyA-E) are present in Arabidopsis thaliana. all right. With the progress of the genome project, Fi’s tochrome-like photoreceptors were found in cyanobacteria, a photosynthetic prokaryotes other than plants. Furthermore, in non-photosynthetic bacteria, a homologue molecule called bacteriophytochrome photoreceptor (BphP) was found in Pseudomonas aeruginosa (Pa) and radiation-resistant bacteria (Deinococcus radiodurans, Dr). Domain structure of phytochrome molecule Phytochrome molecule can be roughly divided into N-terminal side and C-terminal side region. PAS (Per / Arndt / Sim: blue), GAF (cGMP phosphodiesterase / adenylyl cyclase / FhlA: green), PHY (phyto-chrome: purple) 3 in the N-terminal region of plant phytochrome (Fig. 2A) There are two domains and an N-terminal extension region (NTE: dark blue), and phytochromobilin (PΦB), which is one of the ring-opening tetrapyrroles, is thioether-bonded to the system stored in GAF as a chromophore. ing. PAS is a domain involved in the interaction between signal transduction-related proteins, and PHY is a phytochrome-specific domain. There are two PASs and her histidine kinase-related (HKR) domain (red) in the C-terminal region, but the histidine essential for kinase activity is not conserved. 3. Phototropin; photosynthetic efficiency optimized blue light receptor What is phototropin? Charles Darwin, who is famous for his theory of evolution, wrote in his book “The power of move-ment in plants” published in 1882 that plants bend toward blue light. Approximately 100 years later, the protein nph1 (nonphoto-tropic hypocotyl 1) encoded by one of the causative genes of Arabidopsis mutants causing phototropic abnormalities was identified as a blue photoreceptor. Later, another isotype npl1 was found and renamed phototropin 1 (phot1) and 2 (phot2), respectively. In addition to phototropism, phototropin is damaged by chloroplast photolocalization (chloroplasts move through the epidermal cells of the leaves and gather on the cell surface under appropriate light intensity for photosynthesis. As a photoreceptor for reactions such as escaping to the side of cells under dangerous strong light) and stomata (reactions that open stomata to optimize the uptake of carbon dioxide, which is the rate-determining process of photosynthetic reactions). It became clear that it worked. In this way, phototropin can be said to be a blue light receptor responsible for optimizing photosynthetic efficiency. Domain structure and LOV photoreaction of phototropin molecule Phototropin molecule has two photoreceptive domains (LOV1 and LOV2) called LOV (Light-Oxygen-Voltage sensing) on the N-terminal side, and serine / on the C-terminal side. It is a protein kinase that forms threonine kinase (STK) (Fig. 4Aa) and whose activity is regulated by light. LOV is one molecule as a chromophore, he binds FMN (flavin mononucleotide) non-covalently. The LOV forms an α/βfold, and the FMN is located on a β-sheet consisting of five antiparallel β-strands (Fig. 4B). The FMN in the ground state LOV shows the absorption spectrum of a typical oxidized flavin protein with a triplet oscillation structure and an absorption maximum wavelength of 450 nm, and is called D450 (Fig. 1C and Fig. 4E). After being excited to the singlet excited state by blue light, the FMN shifts to the triplet excited state (L660t *) due to intersystem crossing, and then the C4 (Fig. 4C) of the isoaroxazine ring of the FMN is conserved in the vicinity. It forms a transient accretionary prism with the tain (red part in Fig. 4B Eα) (S390I). When this cysteine is replaced with alanine (C / A substitution), the addition reaction does not occur. The effect of adduct formation propagates to the protein moiety, causing kinase activation (S390II). After that, the formed cysteine-flavin adduct spontaneously dissociates and returns to the original D450 (Fig. 4E, dark regression reaction). Phototropin kinase activity control mechanism by LOV2 Why does phototropin have two LOVs? Atphot1 was found as a protein that is rapidly autophosphorylated when irradiated with blue light. The effect of the above C / A substitution on this self-phosphorylation reaction and phototropism was investigated, and LOV2 is the main photomolecular switch in both self-phosphorylation and phototropism. It turns out that it functions as. After that, from experiments using artificial substrates, STK has a constitutive activity, LOV2 functions as an inhibitory domain of this activity, and the inhibition is eliminated by photoreaction, while LOV1 is kinase light. It was shown to modify the photosensitivity of the activation reaction. In addition to this, LOV1 was found to act as a dimerization site from the crystal structure and his SAXS. What kind of molecular mechanism does LOV2 use to photoregulate kinase activity? The following two modules play important roles in this intramolecular signal transduction. Figure 4 (A) Domain structure of LOV photoreceptors. a: Phototropin b: Neochrome c: FKF1 family protein d: Aureochrome (B) Crystal structure of auto barley phot1 LOV2. (C) Structure of FMN isoaroxazine ring. (D) Schematic diagram of the functional domain and module of Arabidopsis thaliana phot1. L, A’α, and Jα represent linker, A’α helix, and Jα helix, respectively. (E) LOV photoreaction. (F) Molecular structure model (mesh) of the LOV2-STK sample (black line) containing A’α of phot2 obtained based on SAXS under dark (top) and under bright (bottom). The yellow, red, and green space-filled models represent the crystal structures of LOV2-Jα, protein kinase A N-lobe, and C-robe, respectively, and black represents FMN. See the text for details. 1) Jα. LOV2 C of oat phot1-to α immediately after the terminus Rix (Jα) is present (Fig. 4D), which interacts with the β-sheet (Fig. 4B) that forms the FMN-bound scaffold of LOV2 in the dark, but unfolds and dissociates from the β-sheet with photoreaction. It was shown by NMR that it does. According to the crystal structure of LOV2-Jα, this Jα is located on the back surface of the β sheet and mainly has a hydrophobic interaction. The formation of S390II causes twisting of the isoaroxazine ring and protonation of N5 (Fig. 4C). As a result, the glutamine side chain present on his Iβ strand (Fig. 4B) in the β-sheet rotates to form a hydrogen bond with this protonated N5. Jα interacts with this his Iβ strand, and these changes are thought to cause the unfold-ing of Jα and dissociation from the β-sheet described above. Experiments such as amino acid substitution of Iβ strands revealed that kinases exhibit constitutive activity when this interaction is eliminated, and that Jα plays an important role in photoactivation of kinases. 2) A’α / Aβ gap. Recently, several results have been reported showing the involvement of amino acids near the A’α helix (Fig. 4D) located upstream of the N-terminal of LOV2 in kinase photoactivation. Therefore, he investigated the role of this A’α and its neighboring amino acids in kinase photoactivation, photoreaction, and Jα structural change for Atphot1. The LOV2-STK polypeptide (Fig. 4D, underlined in black) was used as a photocontrollable kinase for kinase activity analysis. As a result, it was found that the photoactivation of the kinase was abolished when amino acid substitution was introduced into the A’α / Aβ gap between A’α and Aβ of the LOV2 core. Interestingly, he had no effect on the structural changes in Jα examined on the peptide map due to the photoreaction of LOV2 or trypsin degradation. Therefore, the A’α / Aβ gap is considered to play an important role in intramolecular signal transduction after Jα. Structural changes detected by SAXS Structural changes of Jα have been detected by various biophysical methods other than NMR, but structural information on samples including up to STK is reported only by his results to his SAXS. Not. The SAXS measurement of the Atphot2 LOV2-STK polypeptide showed that the radius of inertia increased from 32.4 Å to 34.8 Å, and the molecular model (Fig. 4F) obtained by the ab initio modeling software GASBOR is that of LOV2 and STK. It was shown that the N lobes and C lobes lined up in tandem, and the relative position of LOV2 with respect to STK shifted by about 13 Å under light irradiation. The difference in the molecular model between the two is considered to reflect the structural changes that occur in the Jα and A’α / Aβ gaps mentioned above. Two phototropins with different photosensitivity In the phototropic reaction of Arabidopsis Arabidopsis, Arabidopsis responds to a very wide range of light intensities from 10–4 to 102 μmol photon / sec / m2. At that time, phot1 functions as an optical sensor in a wide range from low light to strong light, while phot2 reacts with light stronger than 1 μmol photon / sec / m2. What is the origin of these differences? As is well known, animal photoreceptors have a high photosensitivity due to the abundance of rhodopsin and the presence of biochemical amplification mechanisms. The exact abundance of phot1 and phot2 in vivo is unknown, but interesting results have been obtained in terms of amplification. The light intensity dependence of the photoactivation of the LOV2-STK polypeptide used in the above kinase analysis was investigated. It was found that phot1 was about 10 times more photosensitive than phot2. On the other hand, when the photochemical reactions of both were examined, it was found that the rate of the dark return reaction of phot1 was about 10 times slower than that of phot2. This result indicates that the longer the lifetime of S390II, which is in the kinase-activated state, the higher the photosensitivity of kinase activation. This correlation was further confirmed by extending the lifespan of her S390II with amino acid substitutions. This alone cannot explain the widespread differences in photosensitivity between phot1 and phot2, but it may explain some of them. Furthermore, it is necessary to investigate in detail protein modifications such as phosphorylation and the effects of phot interacting factors on photosensitivity. Other LOV photoreceptors Among fern plants and green algae, phytochrome ɾphotosensory module (PSM) on the N-terminal side and chimera photoreceptor with full-length phototropin on the C-terminal side, neochrome (Fig. There are types with 4Ab). It has been reported that some neochromes play a role in chloroplast photolocalization as a red light receiver. It is considered that fern plants have such a chimera photoreceptor in order to survive in a habitat such as undergrowth in a jungle where only red light reaches. In addition to this, plants have only one LOV domain, and three proteins involved in the degradation of photomorphogenesis-related proteins, FKF1 (Flavin-binding, Kelch repeat, F-box 1, ZTL (ZEITLUPE)), LKP2 ( There are LOV Kelch Protein2) (Fig. 4Ac) and aureochrome (Fig. 4Ad), which has a bZip domain on the N-terminal side of LOV and functions as a gene transcription factor. 4. Cryptochrome and UVR8 Cryptochrome is one of the blue photoreceptors and forms a superfamily with the DNA photoreceptor photolyase. It has FAD (flavin adenine dinucle-otide) as a chromophore and tetrahydrofolic acid, which is a condensing pigment. The ground state of FAD is considered to be the oxidized type, and the radical type (broken line in Fig. 1B) generated by blue light irradiation is considered to be the signaling state. The radical type also absorbs in the green to orange light region, and may widen the wavelength region of the plant morphogenesis reaction spectrum. Cryptochrome uses blue light to control physiological functions similar to phytochrome. It was identified as a photoreceptor from one of the causative genes of UVR8 Arabidopsis thaliana, and the chromophore is absorbed in the UVB region by a Trp triad consisting of three tryptophans (Fig. 1D). It is involved in the biosynthesis of flavonoids and anthocyanins that function as UV scavengers in plants. Conclusion It is thought that plants have acquired various photoreceptors necessary for their survival during a long evolutionary process. The photoreceptors that cover the existing far-red light to UVB mentioned here are considered to be some of them. More and more diverse photoreceptor genes are conserved in cyanobacteria and marine plankton. By examining these, it is thought that the understanding of plant photoreceptors will be further deepened.

week four of flower I have a feeling these are going to be monsters. I have never had an Auto flower this big before all my other grows with then they have been on the smaller side. so far, they look like they are going strong adding bulk and one is starting to fade in the fan leaves using up the N as the plant needs it. I did do some defoliation. on some fan leaves bigger than my hand this was the warehouse for the nutrients it has been grabbing from the soil. I might do 1 more round of Bloom booster and a Cal mag. the stems are pretty strong and are holding the weight of the buds well. nothing needs to be supported at the moment. cheers all P.S, Roll 2 fatties.

Finito! Le ultime due piante decisamente meglio delle prime due, pesano decisamente di più, i fiori sono più belli e hanno molta resina! Tra una settimana peso tutto, dovrei essere intorno ai 4 etti abbondanti, vedremo 🤞🏼

👉 plants r still alive.......but not for long 👈

The temperatures, humidity, height, and watering volume(if measured) in grow conditions are all averaged for the week. The pH is soil pH. Any watering done by me is well water which is 7.6 pH and 50° F. Any listed nutrients are ml/gallon of soil spread evenly across the top of the soil. Day 1 we had plenty of rain this morning with partly to mostly cloudy skies. The high temperature was 86°F Day 2 we had a high temperature of 91°F. Skies were clear but it was super humid. I defolated some more today. I watered 3-4 gallons from the hose. Day 3 we had a high temperature of 94° with partly cloudy to clear skies. It was super hot and humid. I watered 3-4 gallons from the well. I'm defoliating a few leaves here and there and opening these girls up. Day 4 we had a high temperature of 94 with average humidity of 94. Skies were cloudy and we had thunderstorms that produced high winds and heavy rainfall. Several of my 7 gallon pots that hadn't rooted into the ground were blown over. Day 5 we had a high temperature of 83°F. It was super humid today and we had a very heavy fog this morning. I watered about 4 gallons of well water. Day 6 we had cooler weather today with a high temperature of 78°F. Skies were partly cloudy and I watered about 3 gallons from the hose. Day 7 we had cooler weather again oday with a high temperature of 79°F. Skies were mostly sunny and I watered about 3 gallons from the hose. Overall this week was a success. Unfortunately all three plants have powdery mildew. They are being treated with a bio fungicide. I'm removing leaves a little at a time. I'm going to be more aggressive next week in trying to get this under control. This weather has not helped. We have had one of the wettest, most humid summer since I've been here. Powdery mildew is on several of the native plants along our tree line and yard. It's been an issue and typically fastbuds have had a lot of resistance. This weather has been brutal and I'll be doing what I can to keep this under control. I didn't feed any this week as the plants are showing signs of excess phosphorus and the feather meal breaks down to feed slowly.

Very interesting week now. the buds start to swell up here, as u can see the stem is insane lol this is a freakin autoflower wtf the yield will be insane. shes drinking 3 liters every 2 days with 1ml/l greens sensation 1ml/l calmag and 1000ppm basic nutrient (4-6-6) Npk all under 1 400watt HPS bulb.

So I started getting this weird deficiency several weeks ago, but now it seems to have taken over the entire plant. I know that RO water has no CalMag, but I upped the CaliMagic dose and its just gotten worse. Going to have to consult with some of my growmies to see whats going on.

think to add co2 !!!!!!!

Every week I take leaves off. Only the bigger ones tho I water twice a week but fertilise once

Moved these out back. They seem happy!

Best smoke I've had in years!!!!

Week 12 Flower 8 Pink Rozay This week was all about checking trichomes. Pink Rozay trichomes show mostly milk and amber. There are a few heads that are dark brown that indicate too late to harvest. The older pistils are turning orange brown and water consumption is slowing down. These and the trichome indicators indicate readiness. Based on this, I put Pink Rozay in the cool garage with low light and ice on top of the pot at night this week. Pink Rozay feeding and pics on March 23,& 26 Bloom Juice 120 ml Royal Rush 0 ml Power bud 15 ml Green sensation 15ml Cal Mag 20ml Recharge 5ml Ppm ranged from 676-777 Ph 6.5 Temp 68 Your likes and comments are appreciated. Thanks for stopping by. Growers love 💚🌿 💫Natrona💫

She got some purp

These week we see a big bud evolution, they're strong and healthy, i can not wait to tryout more strains from SweetseedS. The p.p.m is also a little more higher than the last week because we add 2 ml. Of biobizz biobloom on our weekly feeding and all ready for the 3 week of flowers

So if you checked my entry from last week, I updated it to as the Zkittles ended up being male or hermie. Day 7: These plants were fed today with 685 ppm with 1.5 ml/L of HOG Micro and Bloom, 1ml/L of Green Planet Rezin, 1ml/L cal mag and 2ml/L of Green Planet GPF Uptake fulvic acid, PH 6.0. I have been trying to gently move pots and branches to fill the space left by the zkittles and still maintain a level canopy. I have raised the light inch by inch as the plants grow to hopefully have a more tall stacked cola structure. There is 1 light primarily over the Vanilla kush as it seems to want to stretch more than the others and I want to keep its internodes as tight as possible. I have high hopes for the Amnesia Lemon as it’s branch structure could end up producing some solid clusters. The critical kush is similar, Good stacking but lesser branching. There is buds starting on every plant. I contribute that to the week of 14 hours of light and the 2 doses of HOG red sun which helps stacking and speeds up transition to flower. I am excited to see what happens with these over the next couple days and long term what these Barney’s seeds can do. Thanks, Happy Growing 🌱 I am going to update this entry as the week progresses and see how I like that. Update: Day 10- I was away from home working my night shifts and returned home to find dozens of nice little budlets have formed. The plants seem quite happy, color is good, which I like to see cuz I always under feed N in the first bit. I did some mild defoliation to open up lowers. Stems are nicely stacking and about 6” over the trellis. I bent down the stretching Vanilla tops to keep canopy as even as possible.
