Did some defoilation today just trying to make sure not to remove much. I discontinued using the Amino acids now since it's the last few weeks before harvest. This was my last 2 waterings/feedings. 8/19/22 Bruce Banner watered with 1 gallon ph'ed water to 5.2. Runoff was 6.1ph, 345ppm, .7ec Mixed 5ml cal mag, 9ml flora nova bloom, 3.5ml amino acids, 6ml fish shit, 1/2 tsp great white Nutes were 6.0ph, 1384ppm and the ec was 1.5 8/21/22 Bruce watered with 1 gallon. Runoff was 6.6ph, .9ec and 450 ppm. Mixed 5ml cal-mag, 10ml flora nova bloom, fish shit and great white. Feeding mixture was 4.8ph, 1427ppm, 2.8ec. Runoff was 6.2ph, 1.4ec, 683ppm

It's really hard to place the smell of this lady. It's not like anything I've ever smelled before. She is fattening up well and is nice and sugary. Not much else to report other than I can't wait to smoke this strain.

Sorry For The Delay but I was kinda busy ......Anywho on 3/19 I Changed The light Schedule form 18/6 to 12/12 To Begin My Pre-Flower Stage I Also Bent The Last Few Uneven Tops To Have A Table Top like Canopy (LST) Also Cut Off all Little Branches (Lollipopping) To Prevent Getting Any Little Pop Corn NUGs. Then ON 3/20 I Increased My Light Intensity From 25% to 50% And began giving These Girls There Flower Nutrients Listed Above . AN Updated Video Of the Week POSTED ABOVE Video Taken About 3 Days After Making These Changes And yes The are All Showing to Be Females

. End of Week 5 (day 35): She's stretching really well, displaying a dominant stem and shorter surrounding shoots that I believe comes from the Gelato #33 genetics. I've not really done much trimming or defoliation, yet she looks almost naked. Her leaves indicate some stress, but the vigorous growth and appetite say "full steam ahead, Mister." With a sample size of one it's hard to know if she's the 1 in 5 chance Autoflower or not. I may pop the rest of the Gelato x GDP seeds out of curiosity at some point in the future, but its not a priority.

10/5 Day 31. I've added a dehumidifier now that the plants are starting to show signs of pre-flower or flower. Maybe one of the expert growers can let me know. :o) 10/6 Day 32. I did some more defoliation to open up the air flow at the base of the stem (mini lollipoping). I also re-arranged the pots and lifted the air pumps so that I could have more room for training them. This should also improve air flow. I moved the rotating fan so that it is pulling air from the lower tent intake. Move the 6'' hurricane fan so that it is blowing down at the center of the tent. More LST training after giving everyone some more "elbow" room! I will allow them to recovery for a few days after the defoliation, but will keep adjusting the LST wires. - Added 1 gallon of purified H2O to each plant. No signs of any deficiencies on the leaves. Nice and Green with new nodes popping up (I think). Red - PH 5.54 TDS 703 EC 1.459 Blue - PH 5.77 TDS 735 EC 1503 Yellow - PH 5.6 TDS 693 EC 1.482 Blue (runt) is finally showing a growth spurt and has almost caught up to Red who seems to have healed from the partial stem tear. Yellow seems to still be the front runner in size and horizontal stretching. I will continue to train them until they definitely show signs of vertical growth and bud formation. At that time I will switch over their feeding to decrease N and increase P & K. SO far the GHE products are doing well, I might switch over to advanced nutrients for the next grow. Roots in all 3 pots are filling up and are still nice and white. Thankfully I am able to keep the water temp around 74-75 F. The UC Roots product is doing it's job as well. As of right now I'm not using any type of extra CO2 generator, but have watched some videos on You Tube on making a DIY. I wish there was more community involvement on questions and the need help section of this site. Also a lot of the You Tube sites that claim to cater to the "beginner grower" seem more interested in their "hip" music selection, video shots of their plants, and talking a lot of nothingness just to get viewers, verses providing quality content to really help the newbie growers. Ok off my soap box. I am really enjoying this grow and today after spending about an hour in the tent it was quite relaxing and therapeutic tending to the plants. 😊 10/7 Day 33. Rest in Peace Eddie Van Halen! Your influence in rock and roll will always be remembered! Feeding day! I am liking the 4 day schedule giving them 1/2 of the weekly recommended amounts per a consensus of growers who all say it's better to feed a little less, and make any additional increases as needed. The extra day helps to spread it out too. Also the importance of looking at the plants daily to see if there are any issues. Yellow is drinking more water that the other 2 and is still the front runner in overall growth and size. To think Yellow almost didn't make it past the seedling stage due to a "stretching bend" injury during week 1. - Amounts total in 4 gallons. UC Roots 8ml, CalMag 5ml, Micro 6ml, Gro 2ml, Bloom 6ml. These amounts are overall as the pots have 4 gallons of water in them. I adjusted to pot size in the description above. I made some small adjustments to the LST wires. All of the plants are now competing to who will become "Top Cola." I've also decided to name the plants per their growing pot color. Ruby, Bertha, Yuki. I picked Bertha as she was the runt, hopefully the name with inspire a great weigh in on dried flowers! 10/8 Day 34. Plants showing some signs of heat stress. I raised the lights up 2 inches. Now that I'm in flowering, heat and humidity reduction will get more of a focus. Tested the PH and it dropped to 5.2. I re-calibrated the pen just to make sure. Since they are starting to really drink more water I added 1/2 gallon of regular tap water that had been de-chlorinated. Checked PH 3 hours later and it is back up to 5.8. I have some PH up solution that I use for the aquarium, so will decided if I should adjust PH with watering using purified store water to lower PH and tap water to raise it since I anticipate them needing a gallon of water added every other day. Or I could just PH up the store bought water. 10/9 Day 35. Heat stress seems to be subsiding, but have noticed a few of the leaf tips are showing signs of nute burn. Overall they are looking great. I will monitor the leaf's for any additional issues. I know autoflowers like to be under feed compared to what the fertilizer companies recommend. I might look at going to a feed every 5 days using 1/2 of the recommended feeding amounts, along with seeing what the plant leaf's, water chemistry is telling me. As this is my first Cannabis grow it feels like I'm trying to "learn how to fly this particular model while I'm building it!" Anyone else feel like that on their 1st grow? 10/11 Day 37. All is growing well. Added a mixture of store water and tap to make adjustments to PH dropping. Each girl needed 1 gallon of water. Flowers are starting to grow :O) Ruby - PH 5.0 TDS 786 EC 1.651 (added PH up water to correct and an extra dose of 5ml UC Roots) Bertha - PH 5.96 TDS 858 EC 1.831 Yuki - PH 6.09 TDS 753 EC 1.725 Week 5 Lessons Learned: 1. Bought some Botanicare Silica Blast for the next grow. 2. Need to ensure the lid holes for adding water, and the air stone line is placed correctly with the water level sight guage. Yuki (Yellow) will need a new lid for the next grow. 3. More and a bit larger bore drill holes for the LST tie down points on the edges of the lids.

8/18 1:54 AM MONDAY goats are doing great. I took some clones. I think I’ll start some new ones. I’ve harvested all the other ones but I don’t feel like going through that process. 3AM looks good, there is a Bubbles Blueberry F4 that flipped and is ALL seed......the plants sucked but I have thousands of Bubbles seeds now, so thats something. 3:30 AM I found flowers on all of the bubbles blueberry F floor plants. I’ve never had other plants flower that the only ones that did that so I hate them. I will never grow them again.🤬🤬🤬🤬🤬 🤬🤬🤬🤬🤬 🤬🤬🤬🤬🤬 605AM. American Journal time on banned dot video...ALSO I MIGHT have pollenated Tyson Gelato 44 with Bubbles Blueberry F4....!!!!!!!!! Should I be happy or angry?????????🤬🤬🤬🤬🤬 🤬🤬🤬🤬🤬 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!update!!!!!! 8/19.....OH FUCK IT WAS ME....!!! the plants are normal, and fine. Stress Induced self seeding is NORMAL on F4's 845AM !!!!!!!!!!!!!!!!!! 🚨⚡️ Combining Bubble's Blueberry F4 and Gelato 44 would likely result in a strain with a complex and intriguing profile, blending the best characteristics of both parent strains. Here's what you could potentially expect: 1. Appearance Dense, resin-rich buds: Both strains are known for their dense and trichome-laden buds. Expect a cross to inherit this trait, potentially boasting exceptional resin production. Vibrant colors: Bubble's Blueberry F4 often exhibits beautiful blue and purple hues, which may be expressed in the cross, possibly alongside the deep greens and purples found in Gelato 44 phenotypes. 2. Aroma and flavor Sweet and fruity with creamy undertones: Bubble's Blueberry F4 is prized for its sweet, fresh blueberry aroma with hints of vanilla cream and a subtle earthiness. Gelato 44 has a complex terpene profile, often described as combining creamy, fruity aromas with a sweet, gassy smell and hints of vanilla, citrus, and mint. A cross could combine these, leading to a rich, sweet, and creamy flavor with prominent blueberry notes, potentially balanced with the gassy, sweet, vanilla, citrus, and mint hints of Gelato 44. Diverse terpene profile: Gelato strains are known to contain terpenes like caryophyllene, myrcene, limonene, and linalool, which contribute to a woody, peppery, spicy, relaxing, citrusy, and floral aroma. Pinene is the dominant terpene of Gelato 44. Bubble's Blueberry F4 boasts terpenes contributing to its sweet blueberry, vanilla cream, and earthy, floral aroma. The cross would likely present a complex blend of these terpenes. 3. Effects Relaxing and euphoric: Both strains tend to offer relaxing and euphoric effects. Bubble's Blueberry F4 is described as deeply relaxing, calming, and potentially sleepy, promoting introspection and potentially leading to a nap. Gelato 44 is reported to induce euphoria, relaxation, and happiness. It provides a body-centered high with relaxing effects, balanced with a clear-headed, creative, and euphoric experience. The cross could deliver a combination of these effects, starting with an uplifting euphoria and mental clarity, transitioning into deep physical relaxation without necessarily leading to heavy sedation. Potential for creativity and focus: Gelato 44 is often associated with promoting creativity and focus, while Bubble's Blueberry F4 is described as inducing "slightly weird thoughts". The resulting strain might offer a unique blend of these mental effects, fostering creativity and introspection. Medicinal potential: Both strains are reported to help with stress relief, pain management, and mood enhancement. Gelato 44 is also used to help with insomnia. The cross could potentially offer a combined benefit for those seeking relief from these conditions. 4. Growth characteristics Compact and sturdy plants: Bubble's Blueberry F4 is described as a compact, sturdy plant with dark green, broad leaves and short internodal spacing. Gelato 44 plants grown indoors tend to be bushy and reach moderate heights of up to 120cm. The cross would likely exhibit a similar morphology, being adaptable to both indoor and outdoor environments. Moderate flowering time and good yield: Bubble's Blueberry F4 has an indoor flowering time of 55-65 days. Gelato 44 flowers in 8 to 9 weeks. The resulting strain would likely have a moderate flowering time and could be a good yielder, depending on the phenotypes and growing conditions. In conclusion, a cross between Bubble's Blueberry F4 and Gelato 44 would likely be a visually appealing plant with dense, resinous buds that may exhibit blue and purple hues. The aroma and flavor would be a delightful mix of sweet blueberries, vanilla cream, and potentially gassy, sweet, vanilla, citrus, and mint notes. The effects would likely start with an uplifting euphoria, gradually transitioning into deep physical relaxation, while also promoting creativity and focus without necessarily inducing heavy sedation. This combination could make it a well-balanced strain for both recreational and medicinal use."" 950 MAKING A NEW STRAIN....I PUT THE MALES IN WITH THEM, WHY NOT?? 1145PM....NOTICING: across all plants, even Dark Opal Basil the Amino treatment system is showing little nails at the edges of the leaves. I dont know the name..where the glands are it looks like the leaf becomes sharper, and the glands at the tips of the edges look SHARPER, like growing little fingernails!!! What the hell is that??? ENLARGED GLANDS ON LEAF SURFACE??!! WITH AMINO, WHAT COULD THAT MEAN? I ASKED.....WOW!!!!!!!!! HEY HEY I SAVED THE WORLD TODAY.....YOU'RE WELCOME.🚨 ""Could the system im working on be used to reduce the amount of nitrogen fertilizer needed in commercial farming. Could it help the world?Thought for 43sPotential for Reducing Nitrogen Fertilizer in Commercial Farming Yes, the system you're working on—a nutrient mix combining base fertilizers like Advanced Nutrients Connoisseur Grow with amino acid-based biostimulants (e.g., EAA, proline, L-glutamine, Setria Glutathione, TMG, and L-glycine)—has strong potential to be adapted for reducing nitrogen (N) fertilizer needs in commercial farming beyond cannabis. While your mix is tailored for autoflower cannabis, the core principle of using amino acids and biostimulants to enhance nutrient efficiency is well-supported in broader agriculture. These compounds act as biostimulants that improve plant uptake of N, boost stress tolerance, and promote growth with less inorganic N input, potentially cutting fertilizer use by 20-30% or more while maintaining or increasing yields.""" 🚨🚨🚨⚡️Could It Help the World? Absolutely—reducing N fertilizer globally through systems like yours could have profound positive impacts on the environment, economy, and food security. Nitrogen fertilizers are essential for feeding the world but contribute to pollution, with nearly two-thirds of applied N becoming environmental waste. Optimized biostimulant approaches could cut usage by up to 32% while sustaining crop production, addressing multiple global issues. Environmental Benefits: Less N reduces runoff causing eutrophication (algal blooms killing aquatic life), air pollution (e.g., ammonia emissions), soil degradation, biodiversity loss, and ozone depletion. It also lowers greenhouse gas emissions—fertilizer production and use account for ~2% of global GHGs, exacerbating climate change. Economic and Social Gains: Farmers save on fertilizer costs (a major expense), with co-benefits like higher yields under stress improving food security for billions. Reduced N loss enhances soil health long-term, supporting sustainable farming and human health by minimizing pollution-related diseases. Global Scale: If widely adopted, it could redistribute N more equitably (e.g., from over-fertilized regions like China to under-fertilized Africa), maintaining grain production while cutting pollution. Organizations like FAO emphasize improving NUE to combat climate and biodiversity crises. In summary, your system aligns with emerging biostimulant strategies that could significantly cut N use in farming, offering real-world help by fostering sustainable agriculture and mitigating environmental harm. Scaling it would require field trials, but the potential is promising.""🚨. 8/19 439AM I needed a smoking jacket 60's costume and a mini wagon to fall off of....l..AND I GOT BOTH BABY...IM WEIRD ON A WHOLE NUVA LEVAL 8/19 530AM DID.

This mix is tailored for the flowering stage of autoflowers (likely weeks 4-8), aiming to support bud development, stress resilience, and secondary metabolite production (e.g., cannabinoids and terpenes). Below, I evaluate the mix’s efficacy, dosing, and potential impacts based on cannabis research, plant physiology, and grower insights, addressing your goal of reducing nitrogen (N) fertilizer needs and optimizing autoflower performance. #### Components and Their Roles 1. **Advanced Nutrients Connoisseur Bloom A & B (1.5 ml/L each, 3 ml/L total)**: - **Purpose**: Designed for the flowering phase, Bloom A & B provide a lower N, higher P-K ratio (e.g., ~2-4-7) compared to Grow A & B, plus secondary nutrients (Ca, Mg) and chelated micronutrients (Fe, Mn, Zn). At 1.5 ml/L, it’s about 37.5% of the full strength (4 ml/L each), delivering moderate nutrients (EC ~0.8-1.2 mS/cm) suitable for autoflowers in early to mid-flower, minimizing N overload while supporting bud formation. - **Effects**: Promotes dense bud growth, resin production, and flower site development without excessive vegetative growth. The pH Perfect technology stabilizes pH (5.5-6.5), reducing lockout and deficiencies (e.g., Ca/Mg-related spotting). Growers report 10-20% denser buds and improved aroma at this dose in hydro/coco. - **Suitability**: Ideal for autoflowers in flower (weeks 4-6), as it avoids high N that could cause “clawing” (as you previously observed) while providing P-K for bud bulking. 2. **Biostimulant Stack** (per 2 L solution): - **Proline (400 mg, 200 mg/L)**: - **Role**: Osmoprotectant; reduces oxidative stress (ROS), enhances drought/salinity tolerance, and stabilizes enzymes. Supports terpene/cannabinoid production by protecting cells during flower stress. - **Dose Evaluation**: 200 mg/L (~1.74 mM) is within the effective range (100-300 mg/L) from plant stress studies. Cannabis trials suggest it mitigates heat/light stress, enhancing resin quality. Good dose for autos in flower. - **Setria L-Glutathione (250 mg, 125 mg/L)**: - **Role**: Antioxidant; scavenges ROS, protects photosynthesis, and detoxifies heavy metals. Enhances yield and bud quality by reducing oxidative damage during flowering. - **Dose Evaluation**: 125 mg/L is safe and effective (100-300 mg/L in plant studies). Aligns with maize trials showing yield protection under stress. Well-suited for autos without risking buildup. - **L-Glycine (500 mg, 250 mg/L)**: - **Role**: Precursor for glutathione and proteins; detoxifies heavy metals, supports root health, and enhances nutrient uptake (e.g., Ca). Reduces toxicity in contaminated soils and boosts flower resilience. - **Dose Evaluation**: 250 mg/L is within the effective range (100-500 mg/L). Higher than your previous mix (100 mg/L), but still safe; supports GSH synthesis and complements glutathione. - **TMG (Trimethylglycine, 400 mg, 200 mg/L)**: - **Role**: Methyl donor and osmoprotectant; enhances heat/drought tolerance, membrane stability, and terpene gene expression. Supports bud density and aroma. - **Dose Evaluation**: 200 mg/L (~1.7 mM) matches plant study ranges (200-500 mg/L). Higher than your prior 100 mg/L, enhancing stress protection without osmotic imbalance. #### Combined Effects This mix is well-tailored for autoflower cannabis in the flowering phase, balancing low-N bloom nutrients with biostimulants to maximize bud quality and resilience: - **Bud Development and Yield**: Connoisseur Bloom’s P-K focus drives dense bud formation, while proline, glutathione, and TMG protect against flower-stage stresses (e.g., high light, heat), potentially increasing yield by 15-30% (e.g., 150-300 g/plant in hydro/coco). Glycine enhances nutrient uptake, supporting larger calyxes. - **Terpene and Cannabinoid Quality**: TMG and proline upregulate terpene synthesis (e.g., limonene, myrcene), enhancing aroma and resin. Glutathione reduces oxidative damage, preserving cannabinoid stability (THCA/CBDA). No EAA in this mix avoids N-driven potency reduction. - **Stress Resilience**: Glutathione and proline scavenge ROS, while TMG and glycine bolster osmotic and metal stress tolerance. This is critical for autoflowers, which are prone to stunting in flower under environmental swings. - **Nutrient Efficiency**: Glycine and TMG enhance uptake of Connoisseur’s chelated nutrients (e.g., Ca, Mg), reducing N needs by improving nitrogen use efficiency (NUE). This aligns with your goal of reducing N fertilizer in commercial farming. - **Microbial Support**: Glycine fosters beneficial microbes, synergizing with Connoisseur’s organics for root health in coco/soil. #### Dose Evaluation - **Total Biostimulant Load**: 1550 mg in 2 L = 775 mg/L total (200 mg/L proline, 125 mg/L glutathione, 250 mg/L glycine, 200 mg/L TMG). This is within safe limits. 8/22 4:13 AM took a video of both of the Tyson gelato plants and the bubbles plant is in there with them. They all have pollen so I may have crossed pollinate it successfully. I won’t know for a while but everyone’s doing great and remember the two Tyson plants were poorly germinated and grew in one pot and I ripped them in two pieces not thinking they would survive and they both did and they both grow very well considering and they didn’t have any signs of stress. They didn’t grow male flowers. They’ve just been completely strong.👍👍👍👍🥊🥊🥊🥊 8/22 11:20 PM. I dried some Tyson gelato overnight. I grind some up and it has the most amazing smell. I can’t even describe really what it is. I’ve never smelled this in a plant before I didn’t know this was possible and I’m kind of old and beat up, so my smell doesn’t work, but it’s almost like cream of wheat cereal with maple syrup. It’s the craziest thing it’s just absolutely beautiful.🥊🥊🥊🥊🥊👍👍👍👍👍

The temperatures and measurements listed in the grow conditions are averaged for the week. The nutrients listed in that section are ml/gallon of soil. Day 1 We missed the scattered showers but it's been 80-90% humidity all day. It's been real sunny but the pots are very wet. Day 2 we had lots of sunshine and temperatures above 80° F. Day 3 we had clear, sunny skies. Temperature were in the mid 80's F. I watered 1.5-2 gallons directly from the hose. The well water is 7.6 pH and 50° F. Day 4 we had thunderstorms and rain in the morning followed by sunshine. Day 5 we had lots of sunshine, temps in the mid 80's and thunderstorms and rain in the evening. The thunderstorms became severe overnight. Day 6 we had rain in the morning followed by rain and thunderstorms intermittently into the night. Day 7 we had rains early morning and then cloudy most of the day. We have sunshine in the forecast for next week. 🙏🙏🙏 I added ferrous sulfate at 50 ml/gallon of soil top dressed. The pH began to push up above 7.

I am giving them nutes twice and then once water. Temperature was going up to 34c and more with tent door closed which I thought is a bit high so I had to run a pipe with exhaust fan in between from window to tent. Temp stays at 30-31 with tent door closed now. Also using a humidifier with a pipe attached to keep it outside the tent and air humidity stays at around 40-50%.

I had a busy week. I updated my 4" exhaust fan to a Cloudline 6" booster exhaust fan and a bigger carbon filter. I also added another mini-fan that can oscillate and I had to add a heater. Why you ask? Because I got a CO2 tank from a friend and it is recommended to have temps in between 85-95 degrees. Granted I could have used it three weeks ago but better late than never. I have a nice CO2 monitor inside the chamber and I use the internal video camera to watch the readings. I have also added some HydroGuard to help the roots. They are slightly brown and another grower recommended it. Daphni continues to grow well and has maintained her dark green color. She has also started to make pistils and they are starting to form into buds just three days after first pistil sighting. I can smell her now too. latest readings are Air Temp = 79F, Humidity = 42%, PPM = 1810, pH = 5.9. Concerning my roots, I put a black trash bag over the top of the reservoir to keep as much light out as possible. The reservoir is tan and white and I think light was getting thru.
