The plant with all the yellowing is it a deficiency or virus?

Hey now, I hope everyone is having a great weekend. The ladies had another great week, I got the Durban Nights, Red Hot Cookies, and Sundae Driverr's second toppings completed on day 26, and I got the second toppings done on the Green Crack and Bubble Runtz on day 27. Right now I have 4 mains on each plant, and I will top each one this week, probably in the next 3-4 days which will leave with me 8 mains. So the mainlines will be completed during week 5, and I plan to flip to flower around week 7. I am still seeing a couple holes on the leaves of the Sundae Driver, but I have treated her twice with neem oil and I don't see any new holes since the last application and I can't see any bugs even with magnification. I am still not sure if it was a bug issue or just a genetic thing. Either way I am not too concerned at this point because they all seem to be very healthy. I am still feeding GH nutrients, silica, cal mag, and maxi grow. I will transition to flower nutrients approximately one week after flipping to flower. I have found that it is important to continue feeding plenty of Nitrogen through the stretch. The only way I would transition sooner is if I was running out of vertical space. Still very pleased with the Spectrum X from Medic Grow. I am running her at 69% and the plants seem very happy and healthy. The heat and humidity are finally letting up in my region so it is nice to be able to open some windows and drop the temp outside the grow tent. I hope everyone has a great weekend, Thanks for stopping by, Stay Safe and Blaze On!!! 💪 Website: https://medicgrow.com/ https://growdiaries.com/grower/medicgrowled

The cold is taking a toll, that’s for sure. Still looking decent but I’m sure I’ll get my fight with this one ________________________________________________________________________ Light from @MarsHydroLED 😎 FC-E6500🔥 730 Watt⚡️💥 2.85 μmol/J🔥 Full Spectrum 🌈 WiFi smart connection 😱

Just a nasty little runt that couldn’t take the heat and crazy weather! Had this happen twice before with autos specifically. Not going to waste any more time! Oh well! On to the next! ✌️🏻💚

Buds are starting to swell and smell very nice. Not drinking as much water now after the stretch but still drinking a lot. Everything is looking great.

2nd net is up. Early bud formations are promising. holding up to the extremes pretty well, some leaves taking minor damage, but overall, she is holding up, gave her 1 night at 50F see how she would react, stressful. Not advised as it messes with her metabolism, but I want to see if it triggers any anthocyanin response. Love to see her purp up but no signs yet. Remember, For every molecule of glucose produced during photosynthesis, a plant needs to split six molecules of water. This process provides the hydrogen needed for synthesizing glucose and other organic compounds, while oxygen is released as a byproduct. Homework. If Rubisco activity is impaired and it cannot properly function or regenerate its substrate, the plant's leaves are likely to turn a pale green or lime green, a condition known as chlorosis. Essentially, Rubisco activity is highly regulated and susceptible to various environmental and metabolic factors that can cause it to become inhibited, leading to an apparent failure in RuBP regeneration due to a lack of consumption. Rubisco regeneration is intrinsically linked to nitrogen supply because Rubisco is a major sink for nitrogen in plants, typically accounting for 15% to over 25% of total leaf nitrogen. The regeneration phase itself consumes nitrogen through the synthesis of the Rubisco enzyme and associated proteins (like Rubisco activase), and overall nitrogen status heavily influences the efficiency of RuBP regeneration. RuBisCO is a very large enzyme that constitutes a significant proportion (up to 50%) of leaf soluble protein and requires large investments in nitrogen. Insufficient nitrogen supply limits the plant's ability to produce adequate amounts of RuBisCO, thereby limiting the overall capacity for photosynthesis and carbon fixation. Maintaining the optimal, slightly alkaline pH is crucial for the proper function and regeneration of Rubisco. Deviations in either direction (too high or too low) disrupt the enzyme's structure, activation state, and interaction with its substrates, leading to decreased activity and impaired RuBP regeneration. (Lime/yellowing) Structural Component: Nitrogen is an essential building block for all proteins, and the sheer abundance of the Rubisco protein makes it the single largest storage of nitrogen in the leaf. Synthesis and Activity: Adequate nitrogen supply is crucial for the synthesis and maintenance of sufficient Rubisco enzyme and Rubisco activase (Rca), the regulatory protein responsible for maintaining Rubisco's active state. Nitrogen deficiency leads to a decrease in the content and activity of both Rubisco and Rca, which in turn limits the maximum carboxylation rate, Vmax, and the rate of RuBP regeneration Jmax, thus reducing overall photosynthetic capacity. Nitrogen Storage and Remobilization: Rubisco can act as a temporary nitrogen storage protein, which is degraded to remobilize nitrogen to other growing parts of the plant, especially under conditions of nitrogen deficiency or senescence. Nitrogen Use Efficiency (NUE): The allocation of nitrogen to Rubisco is a key determinant of a plant's photosynthetic nitrogen use efficiency (PNUE). In high-nitrogen conditions, plants may accumulate a surplus of Rubisco, which may not be fully activated, leading to a lower PNUE. Optimizing the amount and activity of Rubisco relative to nitrogen availability is a target for improving crop NUE. Photorespiration and Nitrogen Metabolism: Nitrogen metabolism is also linked to the photorespiration pathway (which competes with carboxylation at the Rubisco active site), particularly in the reassimilation of ammonia released during the process. To increase RuBisCO regeneration, which refers to the process of forming the CO2 acceptor molecule Ribulose-1,5-bisphosphate (RuBP) during photosynthesis, the primary methods involve optimizing the levels and activity of Rubisco activase (Rca) and enhancing the performance of other Calvin-Benson-Bassham (CBB) cycle enzymes. Biochemical and Environmental Approaches: Optimize Rubisco Activase (Rca) activity: Rca is a crucial chaperone protein that removes inhibitory sugar phosphates, such as CA1P (2-carboxy-D-arabinitol 1-phosphate), from the Rubisco active site, thus maintaining its catalytic competence. •Ensure optimal light conditions: Rca is light-activated via the chloroplast's redox status. Adequate light intensity ensures Rca can effectively maintain Rubisco in its active, carbamylated state. •Maintain optimal temperature: Rca is highly temperature-sensitive and can become unstable at moderately high temperatures (e.g., above 35°C/95F° in many C3 plants), which decreases its ability to activate Rubisco. Maintaining temperatures within the optimal range for a specific plant species is important. •Optimize Mg2+ concentration: Mg2+ is a key cofactor for both Rubisco carbamylation and Rca activity. In the light, Mg2+ concentration in the chloroplast stroma increases, promoting activation. •Manage ATP/ADP ratio: Rca activity depends on ATP hydrolysis and is inhibited by ADP. Conditions that maintain a high ATP/ADP ratio in the chloroplast stroma favor Rca activity. Enhance Calvin-Benson-Bassham (CBB) cycle enzyme activity: The overall rate of RuBP regeneration can be limited by other enzymes in the cycle. •Increase SBPase activity: Sedoheptulose-1,7-bisphosphatase (SBPase) is a key regulatory enzyme in the regeneration pathway, and increasing its activity can enhance RuBP regeneration and overall photosynthesis. •Optimize other enzymes: Overexpression of other CBB cycle enzymes such as fructose-1,6-bisphosphate aldolase (FBA) and triose phosphate isomerase (TPI) can also help to balance the metabolic flux and improve RuBP regeneration capacity. Magnesium ions, Mg2+, are specifically required for Rubisco activation because the cation plays a critical structural and chemical role in forming the active site: A specific lysine residue in the active site must be carbamylated by a CO2 molecule to activate the enzyme. The resulting negatively charged carbamyl group then facilitates the binding of the positively charged Mg2+ion. While other divalent metal ions like Mn2+ can bind to Rubisco, they alter the enzyme's substrate specificity and lead to dramatically lower activity or a higher rate of the non-productive oxygenation reaction compared to Mg2+, making them biologically unfavorable in the context of efficient carbon fixation. The concentration of Mg2+ in the chloroplast stroma naturally increases in the light due to ion potential balancing during ATP synthesis, providing a physiological mechanism to ensure the enzyme is activated when photosynthesis is possible. At the center of the porphyrin ring, nestled within its nitrogen atoms, is a Magnesium ion (Mg2+). This magnesium ion is crucial for the function of chlorophyll, and without it, the pigment cannot effectively capture and transfer light energy. Mg acts as a cofactor: Mg2+ binds to Rubisco after an activator CO2 molecule, forming a catalytically competent complex (Enzyme-CO2-Mg2+). High light + CO2) increases demand: Under high light (60 DLI is a very high intensity, potentially saturating) and high CO2, the plant's capacity for photosynthesis is high, and thus the demand for activated Rubisco and the necessary Mg2+ cofactor increases. Mg deficiency becomes limiting: If Mg2+ is deficient under these conditions, the higher levels of Rubisco and Rubisco activase produced cannot be fully activated, leading to lower photosynthetic rates and potential photo-oxidative damage. Optimal range: Studies show that adequate Mg2+ application can enhance Rubisco activation and stabilize net photosynthetic rates under stress conditions, but the required concentration is specific to the experimental setup. Monitoring is key: The most effective approach in a controlled environment is to monitor the plant's physiological responses e.g., leaf Mg2+ concentration, photosynthetic rate, Rubisco activation state, and adjust the nutrient solution/fertilizer to maintain adequate levels, rather than supplementing a fixed "extra" amount. In practice, this means ensuring that Mg2+ is not a limiting factor in the plant's standard nutrient solution when pushing the limits with high light and CO2. Applying Mg2+ through foliar spray is beneficial to Rubisco regeneration, particularly in alleviating the negative effects of magnesium (Mg) deficiency and high-temperature stress (HTS). While Mg can be leached from soil, within the plant it is considered a mobile nutrient, particularly in the phloem. Foliar-applied Mg is quickly absorbed by the leaves and can be translocate to other plant parts, including new growth and sink organs. Foliar application of: NATURES VERY OWN MgSO4 @ 15.0g L-1 in a spray bottle. For those high-intensity workouts when 1 meal a day is just not enough! Foliar sprays are often recommended as a rapid rescue measure for existing deficiencies or as a supplement during critical growth stages, when demand for Mg is high. Application in the early morning or late evening can improve absorption and prevent leaf burn. The plant was getting a little limey yellow in the centre. Shortly thereafter, she was back in business, green mostly regenerated. The starting point [of creativity] is curiosity: pondering why the default exists in the first place. We’re driven to question defaults when we experience vuja de, the opposite of déjà vu. Déjà vu occurs when we encounter something new, but it feels as if we’ve seen it before. Vuja de is the reverse—we face something familiar, but we see it with a fresh perspective that enables us to gain new insights into old problems. Confidence is evidence... nothing more. You are confident because you have driven 10,000 times, you are confident because you have spoken 10,000 times. People think confidence is a feeling, but it's not. If you want more confidence, then you need to create evidence, take more shots, collect more data, build more experiences, take more risks; fail, confidence doesn't come first; it is the reward you get for doing the work. no one else wants to do.

Langsam wird es buschig. Ich hab mit Draht einfach die Äste auseinander gezogen. Düngen war bis jetzt nicht Nötig, nur ein wenig Wasser. Bis jetzt wurden die beiden Mädels mit 100watt beleuchtet. Demnächst werde ich die Leistung erhöhen.

Wow! Hard to believe these are autoflowers, I’ve never harvested a cola off an autoflower quite this robust. The hps lights in the 2nd grow room were maybe a bit much and all the plants handled it differently. The big beast is one that did very nicely under the hps lights. The smaller much more frostier dried bud is from the mars hydro ts1000 grow tent. Not nearly the yield or density but beautiful crystal covering the buds. Amazing colour from both the led grow dark devils and the hps ones.

Day 22 giving #2 plant bent her over 24hr lst none for #1 plant. Day 23 #2 plant with lst has shown real big growth. #1 plant no lst and not growing fast. #2 lst ties off now just doing leaf tucking to bring out bottom branches. This process does work. Day 24 filled resivors add my nutrients and got 700ppm with 6.6 ph . Room temp. 78 humidity 47 Day 25 all is good plants growth is great. Day 26 growth is good doing leaf tucking lst on both now. Day 27 #1 little leaf tucking doing well #2 much busher then #1 lst is good for this strain. Day 28 a little defoliation on both

08/26 - Increased water feeds with increased nitrogen - Prepped using clonex mist and clonex gel for cuttings - Pulled 10 clones on the first gen set

Hi liebe Community and Welcome Back! 💚🌱 We proud to present the second Strain from Good Times Genetics! Die Wuchsform der Pflanzen wirkt bis jetzt sehr homogen, es ist zu beachten, dass natürlich die einen etwas schneller wachsen, wie die anderen. Auch die Stielbreite unterscheidet sich etwas. Insgesamt wirken die Jungpflanzen allerdings sehr kompakt, was eine gewisse Indica Dominanz vermuten lässt. Das ist auch so gewollt. Ich werde immer wieder verschiedene Pflanzen der gleichen Zucht dokumentieren und nach der Geschlechtsbestimmung dann Herausfiltern, welche zwei Pflanzen für die Fertigstellung des Diaries in Frage kommen. Die Wachstumsbedingungen im Growzelt sind weiterhin am Optimum und Stabil: ——————— 🌞 Temp: 23°C 🌚 Temp: 20 °C 💨 RH: 58% VPD: 0,86 kPa 😎PPFD: 330 mqm ——————— Stay Tuned! 💚

Alright folks! So this harvest was fantastic! I mean! I’m a happy grower at harvest for any plant! I could harvest one amazing and one meh and be just as happy to cut dry and cure them both! This early miss smoked well and is only about two weeks in cure, this is a rank and musky strain with a whole plethora of combining smells, I find it had a massive pepper and spice hit with almost a food like consistency with its smell, I’m finding a even pine, spice, earthy almost cheesy platform with a fine kick of just a odd but interesting odder I can’t put my thumb on! The density of even the popcorn flower is unreal, rocks all of them. A very light almost desert sandy trichome layer in the interior of the nugs but toward the exterior it’s a lush dark green and red hue with purple calyxes also being seen from the top and Bottom inner and some outer calyxes. The trichome production was very impressive also the fast growth in veg was awesome! But I’m telling you! The big bud genetics and the white widow genetics in this are both prominent, and I love it! I’m saying for a auto it’s pretty potent! And not to say that other autos aren't! We all know they can be pretty Damn amazing! But yeah! The flavour is that of pepper and spice! Pine and a gassy greasy fresh herb blend! I wish I had taken more time to run her though because I believe if I had kept running her, her potency would have been a bit higher and definitely would have achieved a more full couch lock. But over all a easy grow and a dense dense grow. I recommend dropping rh and bringing head up a tad at the end to make those nugs as hard as you can! But that’s my bro advice lol
