One plant "lost" to budrot, luckily the only one which was 5 days older than all other 3. Budrot on 3 main buds, very early stages, noticed rather quickly as I'm a very alert person with stuff like this. Lost around 10% of infected and healthy material, and harvested early on around day 73. I lost around 2 weeks of weight gain & ripening with the early harvest, but I had to do it for the good of the other 3 plants. Infected plant was a Granite Haze F5, quick dry with wet trim to avoid more mold / rot. 5 days of drying at 20°C and 65% humidity, and light breeze of air. Final dry yield was 205g dry out of the second smallest autoflower here. Currently still in its curing stages, still a hay-ish smell to it because of the emergency dry, but I slowly get peppery notes, mixed with liqourice & ass. Yes it stinks. All other 3 plants are good so far, but this week doesn't have lots of images.

Been a rough week and you can see she’s struggling with the heat! It’s been over 95 degrees for a few days now and I’ve been watering the daylights out of her. Kinda stunted from the heat.

-Plants are looking a bit stressed (i missed one watering + i moved the tent to a different appartment) -didnt fertilize this week because they show some signs of over-fertilisation -humidity is too high again but right now i cant do anything about it so i hope they push through Happy for any comment :)

Hallo zusammen 🤙. Sie wächst sehr schön und macht keine Probleme

A new light has been added to the tent. I noticed a bit of a droop for several hours after adding it. After 4 hours they started picking up again. They are quite healthy and seem to be very happy. PH Is around 6.0. It just seems easier to keep it around 6.0. The PH seems to rise to 6 a day after correcting it down to 5.7 so I gave up. PPM is around 1000 and cal mag is being added to help them cope with the higher light intensity during flower. Pk13/14 has been added in a very small amount and a slightly higher does will be used in the next week. Please feel free to comment if you have any info that may help :) please take time to like as it helps me know if this is worthwhile updating. Microgrowery

Shes only getting calmag and overdrive for 4 days, next week i chop it down

wow ! bud all over tent ! really good smell like fruit loop lime ! but i think all its good for now ! new soup with cal mag ,pk13/14,cannazym,cannaboost and terpinator! she like so healty next time sativa will be in bigger tent !

Hey guys so it was an easy and nice run, a little bit disappointed with the outcome, only 223g with 3 plants but happy with the quality of the buds. Plant n.1 : 99g Plant n.2 : 63g Plant n.3 : 61g The curing phase start today so I will update soon for the smoke report.

Giorno 49 Ho girato in fioritura. Le due Zombie come già detto nelle settimane scorse sono due fenotipi completamente diversi. Uno sicuramente haze e l'altro bubba Kush. Stanno bene entrambe ma la più grande l'ho dovuta defogliare per bene e sono certo che tra 15/20gg farò una seconda passata. Ultima bevuta prima di mandare in fioritura EC 1.28 ph 5,8. Anche le due Rainbow Belts sono diverse perché sfregando il gambo una sa di Zkittlez l'altra di frutta quindi penso più a qualche fenotipo dosidos. La Milk Monkey è quella che per struttura mi piace più di tutte. Per la prima volta ho preso dei cloni anche se non so dove tenerli e sotto che luce. Per ora li ho messi in un vaso ricoperto da velina nel box delle autofiorenti

Week 6 and another feeding bumping up the PPM to 1250 ph. 5.8 3 of the 5 are about where I expected them, Think Different is really dense not a lot of stretch on that one. Baby Blue Dream is in ICU for the most part. I laid off the food and water until it dry's out a bit more. Takeaways this week... This is my 1st attempt at autos and 5 different strains at that. A lot of opportunities for learning here. watering feeding transplanting all play into my current results. The Green Buzz nutrients are amazing the sample kit I got is just enough for the 6 autos. I should finish all of them by the end of the grow the size of the bottles were just the perfect amounts for each phase VEG, TRANS & FLOWER with regular watering's as needed in-between feedings. looking forward to some more stretch and filling in the Scrog. I just gave it a 2 gallon flush of PH 6.p water in each pot the remainder in the pan was wicked up the next day hoping for more roots to spread. Until next week Merry Christmas to all and the GW Staff.😇

She’s grown lovely over the last week and has more than doubled in size. The weather last week was fairly mild, with an average temperature of 20 degrees. She’s healthy and full of life.

26/06 Sie wächst großartig. Die Buds entwickeln sich und bekommen langsam Trichome. Man kann erkennen, dass Sie anfängt zu purplen. - - - - - - - - - - - - - Dünger wurde bisher nicht zugegeben.

08.05 Day 49 Fortnightly tent clean out, wipe and dry. Moved all the plants around again. 10.05 Sunday Day 51 Cheese cookies is showing signs of severe over feeding. Going to give her just water for a while. The other 3 look great and are coating with resin already. Going to reduce the a+b feed down to 1ml for a while. Big devil and six shooter have a citrusy smell. Sweet cheese smells like pineapple and is the strongest smell out of all. Tuesday 12.05 Day 53 Got my self a tds meter, finally. I'll now be able to make smaller, minute adjustments if necessary. So cheese cookies at the moment is only getting pk boost + head master =650ppm. The other 3 are being fed at 1100ppm, they seem to be loving it. Spread sweet cheese out a little bit more again. So many lovely bud sites on her!👍🌱 Smell is slowly starting to increase but still very mild smells of citrus, pine and tropical fruits. 15.05 Day 55 Buds on the 2 sweet seed plants are getting covered in trichs. The six shooter and cheese cookies are probably going to take alot longer.

Seventh week, day 46, keeping on cropping and LST, dominant colas in #1 have been fimmed and #3 has been topped. The stretch should start within a few days. Feeding schedule is going to change just after the stretch.

Last week of Vega. Now it's time for Flora!!💐💐

7/28 1220AM MONDAY.... Bubbles are looking ok, I need to trim them back to 4 colas, I am really stressing them with small space limitations, and temps at 80 to 81 7/29 Tuesday 5:45 AM💦💦 6:15 AM water with methylene blue two pills of nitric boost amino acid, five drops of Quick Sorb and I added bud factor X today and a quarter mL per liter of rhino silica💦💦💦. 1030 AM I don’t know what I’m gonna do. It turns out the bubbles plants are terrible. The stems are all very weak and they’re growing bushy at the top. I didn’t get them separated so all of the side branches grew up really long it’s completely useless. It is absolute this plant. It will be thrown in the garbage. Can you fucking believe I have to throw another entire plant in the fucking garbage😡😡😡😡. TREVOR plant cut down to 2 colas only, very top heavy not liking my grow space, had 2 more than I wanted so it's all fucked.... will remove shitty small colas and get maybe 2 good colas per plant, not expecting much. 1219pm....HOLY SHIT I FUCKED THESE.....TOOK OFF SOME COLAS.....NOT ENOUGH SPACE AND I PUSHED THEM TOO FAR.....I CAN FIX IT 7/30 1215am found a GREAT science link::: ""https://www.frontiersin.org/research-topics/8125/cannabis-genomics-breeding-and-production/magazine"". 345am PROLINE WILL BE HERE TODAY.ALL RESEARCH INDICATES PROLINE WILL PROTECT FROM HEAT STRESS!!!! 11:30 AM they are good again they are recovering from heavy defoliation half of the plant was taken off of one of them. I pushed it a little far but today they are recovering from heat and lack of air and lack of space the leaves are reaching up and they are not folding under heat stress. They look good today. Fast recovery heavy amino yesterday.👍👍👍👍🚨🚨🚨🚨 🚨🚨🚨🚨🚨🚨🚨🚨 GOT THE AMINOS AND HERE IS THE GROK RESULT OF MY MIX.......🚨🚨🚨🚨🚨🚨🚨🚨 The effects of applying essential amino acids (EAAs), proline, trimethylglycine (TMG), and glutamine to cannabis plants can be significant, as these compounds act as biostimulants, influencing growth, stress resilience, and secondary metabolite production. The available research, primarily from studies on amino acids in plants, including cannabis, provides insights into their roles, though specific data on this exact combination is limited. Below, I summarize the effects of each compound on cannabis plants, drawing from relevant studies, and infer potential synergistic effects based on their known roles in plant physiology. Note that TMG (betaine) has less direct research in cannabis, so some effects are extrapolated from other plants. ### 1. Essential Amino Acids (EAAs) EAAs (e.g., leucine, lysine, methionine, etc.) are critical building blocks for proteins and play roles in plant metabolism and stress response. In cannabis: - **Growth and Development**: EAAs enhance protein synthesis, supporting shoot and root growth. Foliar or soil application of EAAs (e.g., 150–300 mg/L) increases leaf chlorophyll, shoot biomass, and root development in various plants, likely applicable to cannabis.[](https://www.nature.com/articles/s41598-022-21273-6) - **Nutrient Uptake**: EAAs like methionine and lysine improve nutrient absorption (e.g., nitrogen, iron) by acting as chelators, potentially enhancing cannabis nutrient efficiency in hydroponic or soil systems.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/)[](https://mycsainc.com/newsletter/en/2023/03/03/amino-acids-and-their-function-in-plants/) - **Stress Mitigation**: EAAs, particularly methionine, support antioxidant production (e.g., glutathione), reducing oxidative stress from drought, salinity, or high light, common in cannabis cultivation.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2020.00928/full)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Cannabinoid/Terpene Production**: Limited evidence suggests EAAs may influence secondary metabolism. For example, methionine could enhance sulfur-containing compounds, potentially affecting terpene profiles in cannabis.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) **Application Notes**: EAAs are often applied via foliar spray (150–300 mg/L) or soil drench. Overuse may lead to nitrogen imbalance, so moderation is key.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) ### 2. Proline Proline is a non-essential amino acid that accumulates in plants under stress and serves multiple functions: - **Stress Tolerance**: Proline acts as an osmolyte, stabilizing cell membranes and scavenging reactive oxygen species (ROS) during drought, salinity, or temperature stress. In cannabis, exogenous proline (e.g., 50–100 mM) may enhance tolerance to environmental stressors, improving resilience in outdoor or controlled environments.[](https://www.researchgate.net/publication/349966775_THE_ROLE_AND_IMPORTANCE_OF_AMINO_ACIDS_WITHIN_PLANTS_A_REVIEW)[](https://pmc.ncbi.nlm.nih.gov/articles/PMC3548871/) - **Limited Growth Effect**: Proline alone is a poor nitrogen source for growth. Studies on Arabidopsis show it has a neutral or inhibitory effect on growth when used as the sole nitrogen source, suggesting it’s better for stress response than biomass accumulation.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Cannabis-Specific**: Proline helps cannabis maintain water balance, potentially improving resistance to extreme temperatures, which is critical for outdoor grows.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) **Application Notes**: Foliar or root application (50–100 mg/L) is effective for stress mitigation. High doses may inhibit growth if not balanced with other nutrients.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full)[](https://www.researchgate.net/publication/349966775_THE_ROLE_AND_IMPORTANCE_OF_AMINO_ACIDS_WITHIN_PLANTS_A_REVIEW) ### 3. Trimethylglycine (TMG, Betaine) TMG is less studied in cannabis but known as an osmoprotectant and methyl donor in other plants: - **Stress Protection**: TMG stabilizes proteins and membranes under salinity, drought, or temperature stress, similar to proline. It may protect cannabis plants in harsh conditions, maintaining photosynthetic efficiency.[](https://www.mdpi.com/2311-7524/9/7/807) - **Methylation Support**: TMG donates methyl groups, potentially enhancing secondary metabolite synthesis (e.g., cannabinoids, terpenes), though direct evidence in cannabis is lacking. Its role in methylation could support metabolic pathways linked to EAAs and glutamine. - **Growth Effects**: Limited data suggest TMG may improve chlorophyll content and photosynthesis, indirectly supporting biomass in cannabis. **Application Notes**: TMG is typically applied at 0.5–2 g/L via foliar spray. Its effects in cannabis are inferred from other crops, so careful experimentation is needed. ### 4. Glutamine Glutamine is a conditionally essential amino acid central to nitrogen metabolism: - **Growth Promotion**: Glutamine (10–1000 mg/L) significantly enhances shoot elongation, root growth, and chlorophyll content in plants like lettuce and hibiscus, likely benefiting cannabis vegetative growth. In cannabis, it may support lush foliage and robust rooting in hydroponics.[](https://www.scielo.br/j/oh/a/GZxMgqXb9wm7bsCTv4WwPdc/?lang=en)[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html)[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html?lang=en) - **Nitrogen Assimilation**: As a primary nitrogen acceptor, glutamine improves nitrogen use efficiency via the glutamine synthetase/glutamate synthase cycle, enhancing nutrient uptake in cannabis.[](https://academic.oup.com/jxb/article/58/9/2339/544408)[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) - **Stress Response**: Glutamine supports proline synthesis, boosting stress tolerance. It also contributes to chlorophyll and protein synthesis, improving photosynthesis and yield potential in cannabis.[](https://www.mdpi.com/2311-7524/8/12/1110)[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) - **Secondary Metabolism**: Glutamine is a precursor to glutamate, which influences GABA, arginine, and proline synthesis, potentially affecting cannabinoid or terpene production indirectly.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) **Application Notes**: Foliar sprays (250–1000 mg/L) or root application twice weekly are effective. Glutamine at 250 mg/L combined with other amino acids (e.g., glycine) shows synergistic growth effects.[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html) ### Synergistic Effects on Cannabis - **Growth and Yield**: The combination of EAAs, glutamine, and proline may enhance vegetative growth and biomass. Glutamine and EAAs drive protein synthesis and nitrogen uptake, while proline supports tissue integrity under stress. TMG likely amplifies these effects by improving cellular hydration and methylation, potentially increasing leaf area and bud quality.[](https://www.mdpi.com/2311-7524/8/12/1110)[](https://www.nature.com/articles/s41598-022-21273-6) - **Stress Resilience**: Proline and TMG act as osmoprotectants, while EAAs and glutamine bolster antioxidant systems, collectively improving cannabis resilience to drought, salinity, or temperature extremes common in cultivation.[](https://www.mdpi.com/2311-7524/9/7/807) - **Secondary Metabolites**: Glutamine and TMG may enhance cannabinoid and terpene production by supporting metabolic pathways (e.g., methylation, nitrogen metabolism). EAAs like methionine could influence sulfur-based terpenes. However, direct evidence for cannabinoid enhancement is sparse.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Nutrient Efficiency**: Glutamine and EAAs improve nitrogen and micronutrient uptake, while TMG may enhance nutrient transport, optimizing cannabis growth in nutrient-limited systems like hydroponics.[](https://mycsainc.com/newsletter/en/2023/03/03/amino-acids-and-their-function-in-plants/) ### Potential Risks and Considerations - **Inhibition at High Doses**: High concentrations of proline or certain EAAs (e.g., lysine, valine) can inhibit growth if used as sole nitrogen sources. Balanced mixtures mitigate this, as glutamine can antagonize inhibitory effects of proline or other amino acids.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Nitrogen Overload**: Excessive EAAs or glutamine may lead to nitrogen toxicity, causing leaf burn or stunted growth in cannabis. Monitor plant response and maintain balanced nutrient solutions.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) - **TMG Metabolism**: TMG may increase trimethylamine production in the soil microbiome, potentially affecting cannabis root health if not managed. Healthy soil microflora can mitigate this.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) - **Application Timing**: Foliar sprays (150–500 mg/L for EAAs, glutamine, proline; 0.5–2 g/L for TMG) during vegetative growth or early flowering maximize benefits. Avoid overuse during late flowering to prevent nutrient imbalances affecting bud quality. ### Cannabis-Specific Insights - **Hydroponics and Soil**: In hydroponic systems, EAAs and glutamine ensure efficient nitrogen delivery, while proline and TMG support stress resistance in fluctuating pH or nutrient conditions. In soil, maintaining microflora is crucial, as it naturally supplies amino acids; supplementation should be moderate.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Cultivar Variability**: Cannabis cultivars differ in nutrient demands and stress responses. Sativa-dominant strains may benefit more from proline and TMG for stress tolerance, while indica strains may respond better to EAAs and glutamine for dense bud growth. Testing is needed. - **Secondary Metabolites**: While amino acids influence secondary metabolism, direct effects on THC or CBD levels are unconfirmed. Glutamine and TMG may indirectly enhance terpene diversity via improved photosynthesis and methylation.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) ### Practical Recommendations "🚨🚨🚨🚨"🚨🚨🚨🚨"🚨🚨🚨🚨 - **Dosing**: Apply EAAs (150–300 mg/L), glutamine (250–500 mg/L), proline (50–100 mg/L), and TMG (0.5–1 g/L) via foliar spray or root drench twice weekly during vegetative growth and early flowering. - **Combination**: Use a balanced mix (e.g., 250 mg/L EAAs + 250 mg/L glutamine + 50 mg/L proline + 500 mg/L TMG) to avoid inhibition. Test on a small batch first.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Monitoring**: Check for signs of nitrogen toxicity (dark green leaves, clawing) or stress relief (improved vigor, greener leaves). Adjust doses based on plant response. "🚨🚨🚨🚨"🚨🚨🚨🚨"🚨🚨🚨🚨. - **Synergy with Nutrients**: Pair with balanced NPK fertilizers and micronutrients (e.g., iron, calcium) to enhance uptake.[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html) - **Cultivation Context**: In hydroponics, use lower doses to avoid nutrient lockout. In soil, ensure healthy microbial activity to complement amino acid supplementation.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) ### Evidence Gaps - **Specific Combination**: No studies directly address EAAs, proline, TMG, and glutamine together in cannabis. Effects are inferred from individual amino acid studies and general plant research. - **Cannabinoid Impact**: Limited data on how these compounds affect THC/CBD levels. More research is needed on secondary metabolite pathways.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **TMG in Cannabis**: TMG’s effects are extrapolated from other crops. Cannabis-specific trials are needed to confirm benefits. ### Conclusion Applying EAAs, proline, TMG, and glutamine to cannabis plants can enhance growth, stress tolerance, and nutrient uptake, with potential benefits for yield and secondary metabolite production. EAAs and glutamine drive biomass and nitrogen efficiency, proline and TMG bolster stress resilience, and their combination may optimize cannabis health in challenging environments. However, careful dosing and monitoring are crucial to avoid inhibition or toxicity. For best results, test small-scale applications and consult with a horticulturist familiar with cannabis cultivation. If you want more details on application methods, specific cultivars, or further searches for cannabis-related studies, let me know!""🚨🚨🚨🚨 🚨🚨 7/31 125am!!!!! Adding L-glycine to the combination of essential amino acids (EAAs), proline, trimethylglycine (TMG), and glutamine can further influence the effects on cannabis plants, as glycine is a non-essential amino acid with unique roles in plant physiology. Below, I outline the potential effects of L-glycine alone and in combination with the previously mentioned compounds, focusing on their impact on cannabis growth, stress response, and secondary metabolite production. Since specific studies on this exact combination in cannabis are lacking, I’ll integrate findings from plant science and infer synergistic effects based on known mechanisms. I’ll keep it concise and tailored to cannabis cultivation. ### Effects of L-Glycine on Cannabis Plants L-Glycine is a simple amino acid involved in protein synthesis, stress response, and metabolic pathways: - **Growth Promotion**: Glycine (50–500 mg/L) enhances shoot elongation, root growth, and chlorophyll content in plants like lettuce and rice, likely benefiting cannabis vegetative growth. It serves as a nitrogen source and supports protein synthesis, complementing EAAs and glutamine. - **Stress Tolerance**: Glycine acts as a precursor to glutathione, a key antioxidant, reducing oxidative stress from drought, salinity, or high light. In cannabis, it may improve resilience in challenging environments (e.g., outdoor grows or high-intensity indoor setups). - **Secondary Metabolism**: Glycine is a precursor to purines and chlorophyll, potentially enhancing photosynthesis and energy metabolism. It may indirectly influence cannabinoid and terpene production by supporting metabolic pathways, though direct evidence in cannabis is limited. - **Nutrient Uptake**: Glycine chelates micronutrients (e.g., iron, zinc), improving their availability, which is critical for cannabis in hydroponic or nutrient-poor soil systems. **Application Notes**: Foliar sprays or root drenches (100–500 mg/L) are effective, often applied twice weekly during vegetative growth or early flowering. ### Synergistic Effects with EAAs, Proline, TMG, and Glutamine Adding L-glycine to the mix may enhance the effects on cannabis plants in the following ways: 1. **Enhanced Growth and Biomass**: - **Glycine + EAAs/Glutamine**: Glycine complements EAAs and glutamine in protein synthesis and nitrogen metabolism. Studies show glycine (250 mg/L) combined with glutamine enhances shoot and root growth in plants, likely amplifying cannabis vegetative vigor and bud development. - **Synergy**: Glycine’s role in chlorophyll synthesis boosts photosynthesis, supporting the energy demands of EAA-driven protein synthesis and glutamine’s nitrogen assimilation, potentially increasing leaf area and yield. 2. **Improved Stress Resilience**: - **Glycine + Proline/TMG**: Glycine and proline both contribute to glutathione production, enhancing antioxidant defenses. TMG’s osmoprotectant properties further stabilize cells under stress. Together, they may improve cannabis tolerance to drought, heat, or salinity, maintaining growth in adverse conditions. - **Cannabis-Specific**: This combination could be particularly beneficial for outdoor cannabis or indoor setups with inconsistent temperature/humidity, reducing leaf wilting or nutrient stress. 3. **Secondary Metabolite Production**: - **Glycine + Glutamine/TMG**: Glycine and glutamine are precursors to metabolic pathways (e.g., GABA, purines) that may influence cannabinoid and terpene synthesis. TMG’s methyl donation could enhance these pathways by supporting enzyme activity. While direct evidence is sparse, this stack may increase terpene diversity or cannabinoid yield in cannabis buds. - **EAAs Contribution**: Methionine (an EAA) and glycine may support sulfur-containing compounds, potentially enriching terpene profiles. 4. **Nutrient Efficiency**: - **Glycine + EAAs/Glutamine**: Glycine’s chelating properties enhance micronutrient uptake, complementing EAAs and glutamine’s role in nitrogen assimilation. This could optimize nutrient use in hydroponic cannabis systems, reducing nutrient lockout. - **TMG Synergy**: TMG’s role in cellular hydration may improve nutrient transport, amplifying glycine’s effects on micronutrient availability. ### Potential Risks and Considerations - **Inhibition at High Doses**: High glycine doses (1000 mg/L) may inhibit growth by disrupting nitrogen balance, especially if combined with EAAs or glutamine. Studies on Arabidopsis show glycine can be toxic as a sole nitrogen source, so balanced mixtures are crucial. - **Nitrogen Overload**: Adding glycine to EAAs and glutamine increases nitrogen input, risking toxicity (e.g., leaf burn, stunted growth) in cannabis. Monitor for dark green leaves or clawing and adjust doses. - **Competition for Absorption**: Glycine, EAAs, and glutamine may compete for root or foliar uptake, reducing efficacy. Split applications (e.g., glycine in the morning, EAAs/glutamine post-light cycle) can help. - **TMG Interaction**: Glycine and TMG both influence methylation pathways, but excessive methyl donors could disrupt metabolic balance in sensitive plants. Stick to moderate doses (e.g., 100–500 mg/L glycine, 0.5–1 g/L TMG). - **Cultivar Variability**: Cannabis strains (e.g., sativa vs. indica) differ in nutrient and stress responses. Glycine’s benefits may be more pronounced in stress-prone sativas or nutrient-sensitive hybrids. ### Practical Recommendations - **Dosing**: Combine glycine (100–500 mg/L), EAAs (150–300 mg/L), glutamine (250–500 mg/L), proline (50–100 mg/L), and TMG (0.5–1 g/L) in a balanced foliar spray or root drench. Apply twice weekly during vegetative growth and early flowering. - **Application**: Use foliar sprays for rapid uptake during vegetative stages or stress events. Root drenches suit hydroponic systems. Test on a small batch to assess plant response. - **Monitoring**: Watch for nitrogen toxicity (dark, curled leaves) or stress relief (greener, more vigorous plants). Adjust concentrations based on cultivar and growth stage. - **Synergy with Nutrients**: Pair with balanced NPK fertilizers and micronutrients (e.g., iron, calcium) to maximize glycine’s chelating benefits. Ensure adequate magnesium for chlorophyll synthesis. - **Cultivation Context**: In hydroponics, use lower doses to avoid nutrient imbalances. In soil, maintain healthy microbial activity, as microbes naturally produce glycine and other amino acids. ### Evidence Gaps - **Specific Combination**: No studies address glycine combined with EAAs, proline, TMG, and glutamine in cannabis. Effects are inferred from individual amino acid studies and general plant research. - **Cannabinoid/Terpene Impact**: While glycine may support secondary metabolism, direct effects on THC/CBD or terpene levels are unconfirmed. Cannabis-specific trials are needed. - **TMG and Glycine**: Their combined effects on methylation in cannabis are speculative, as most TMG research focuses on other crops. ### Conclusion Adding L-glycine to EAAs, proline, TMG, and glutamine likely enhances cannabis growth, stress tolerance, and nutrient efficiency by supporting protein synthesis, antioxidant production, and micronutrient uptake. The combination may improve vegetative vigor, bud quality, and resilience to environmental stressors, with potential (but unconfirmed) benefits for cannabinoid and terpene production. Careful dosing and monitoring are essential to avoid nitrogen toxicity or absorption competition. Start with low doses, test on a small scale, and consult a cannabis cultivation expert for tailored advice. If you want me to search for more studies, focus on a specific aspect (e.g., glycine’s role in terpene synthesis), or provide application protocols for a particular cannabis strain, let me know!"""
