This was the Athena blended line nutrition grow. She did well. No major growing issues. She has a pretty flower that is frosty, and sticky. She has a very tropical, and fruity smell. Thank you ILGM, Medic Grow, and Athena. Be sure to check out the other fruity pebbles auto diary I have. The two plants had very different structures. ๐Ÿคœ๐Ÿป๐Ÿค›๐Ÿป๐ŸŒฑโ„๏ธ๐ŸŒฑ Thank you grow diaries community for the ๐Ÿ‘‡likes๐Ÿ‘‡, follows, comments, and subscriptions on my YouTube channel๐Ÿ‘‡. โ„๏ธ๐ŸŒฑ๐Ÿป Happy Growing ๐ŸŒฑ๐ŸŒฑ๐ŸŒฑ https://youtube.com/channel/UCAhN7yRzWLpcaRHhMIQ7X4g

This is the light that Iโ€™m using for this grow! Day 47: I can see signs of N toxicity, as always for me hahaha! I go to heavy in the nutes. So flushed her today to make her use the nutes stored inside. Then start over with a lower dose Mars hydro TS-1000 Increase Yield & Crop Quality in Led Grow Newest SMD Led technology provides the highest Par/Lumen output, makes you get 30% higher yield compare old led lights, can get up to 2.5g/watt yield. Only 150 watts true output so you don't have to check your bill every month. 342 pcs LEDs, more scientifically and energy-efficient! Perfect for 3'x3' (100x100cm) veg stage and 2'x2' (60x60cm) bloom stage https://www.instagram.com/marshydro_aliexpress2/

He tenido unos problemas esta semana. Una de las plantas no tiene orden jajaja. Al parecer sus ramas no estรกn muy fuertes y se caen. Acรก es donde me arrepiento de no haber usado scrog. Otras dos plantas estรกn presentando un poco de amarillo en las puntas de las hojas y una que otra un poco quemado justo en la punta color amarilla. Por lo demรกs las veo bien, se hicieron un poco mรกs gordas, pero no lo suficiente o lo que quisiera. Necesito incorporar co2 y scrog en el prรณximo cultivo. Espero resolver mis problemas y mejorarlas para la otra semana. Buenos humos

Hi all.. Lady's are very happy..still stretching a bit..looks like the push is almost over. Very faint sweet smell starting to come form them. Im going to do another light defoliation soon. Humidity is a bit high and i want to avoid WPM. Sorry for all the wierd couler photos , i try take picks as the lights come on.. I will upload some more picks on friday. Other then that..Perfect! ๐Ÿ˜ 420 for life.

Green Cure CBD is growing good for a solo cup grow. She got her first lst and defoliation today. She grew 2 inches over the course of the week. I figure in about 2 weeks she will be root bound. Everything is looking good.

Went from 450w to 150w blue for a week due to heat and too much height gain. Weather got cold so I put the 450w red back in as they seem to be thickening up. Feminising was very easy on the ones I chose, I chose only three that had thicker faster flowering and more THC but will cross with the more sativa dominant ones.

~ GG4 SHERBET FAST FLOWER by FastBuds ~ Well fam, here we go again with another epic strain from FastBuds Fast Flowering stable. After having such tremendous success growing their Gorilla Cookies Fast Flower outdoors last year, I've decided to run another of their fast flowering strains outdoors this year... GG4 Sherbet Fast Flower! The best description of this awesome cultivar comes directly from my friends at FastBuds which is as follows: "Bred from extremely potent and flavorful Gorilla Glue and Orange Sherbet genetics, GG4 Sherbet FF (Fast-Flowering) takes all the best traits to the next level, offering a high-yielding strain that can produce up to 600 g/m2 in a 7-week flowering time. This super resilient Indica-leaning hybrid thrives indoors and outdoors, and in all types of climates while producing mouth-watering sweet, fruity, spicy and earthy terps that translate into a delicious sugary hazelnut aroma. Expect an extremely relaxing and overall happy effect thatโ€™ll leave you with a huge smile from ear to ear. Itโ€™s the perfect strain for growers of all levels of experience seeking low-maintenance yet highly productive photoperiod varieties that deliver quality and quantity without extra effort. GG4 Sherbet FF grows chunky buds with long dark orange hairs and spade-shaped calyxes that get encrusted with trichomes by harvest time, giving them a gorgeous silvery-white appearance. This medium-sized photoperiod can reach up to 200 cm in height and yields up to 650 g/m2 while developing that typical hybrid structure. GG4 Sherbet FF grows with a stocky, bushy appearance, developing one sturdy main cola and fat side branches that support huge yields without much effort. This super-fast variety produces distinctive light-green buds with a high bud-to-leaf ratio, making your trimming sessions a breeze. Itโ€™s a top-notch resin producer that doesnโ€™t need much maintenance and will thrive in almost every climate, rewarding growers of all levels with extremely flavorful resin that makes for outstanding hash end extracts." ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The Setup: This is going to be an outdoor grow, but I have started the GG4 Sherbet Fast Flower indoors as our weather is still too cold to put her outside (nighttime temp's dipping regularly into the 30'sโ„‰). The plan is simple... let her grow inside under a 19/5 light schedule until the nighttime temperatures stay above the mid 40'sโ„‰, at which point she'll be moved outside and transplanted into the soil which I have already setup and inoculated with beneficial microbes, and then let the fun begin!๐Ÿคช๐Ÿ’š ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Weekly Updates: 8/10- Wow! Here we go into Week 4 of flower for the GG4 Sherbet Fast Flower by FastBuds and this lady is on a mission! The GG4 Sherbet FF has large cola's forming all over her and they are rapidly stacking up. Her flowers are continuing to develop and are beginning to get a thick layer of trichomes on them! 8/12- Today, the daily watering routine continues at sunset with around 5g of well water from the hose. I also went into the canopy and removed a bunch of dead and/or completely yellowed leaves to keep the foliage clear of debris which can cause insect and fungal issues if allowed to get out of hand. 8/14- I am continuing to water the FastBuds GG4 Sherbet Fast Flower daily with 5-8 gallons of well water from the garden hose. Yesterday, I top dressed the FastBuds GG4 Sherbet FF with 3 cups of Gaia Green 2-8-4 Power Bloom which I watered in with well water from the hose. I then applied 1/2 gallon of a nutrient mix I made up in 2 1/2g of well water consisting of: 1/4 cup Neptune's Harvest Seaweed(kelp) plant food and 2 1/2 tsp. of Plantonics Amino Bliss. 8/16- We have rain in the forecast over the next three days. There were a couple of passing light rain showers today which didn't provide a lot of rain so I went ahead and watered the GG4 Sherbet FF with approximately 5g of well water just to make sure that she didn't get thirsty. There's a month in flower for this beautiful fast flowering cultivar from the experts at FastBuds and all I can say is WOW! I can't say enough positive things about this strain and will, for sure, be running it again! See you next week!๐Ÿ˜ŽโœŒ๏ธ Thank you for checking out my diary, your positive comments and support make it all worthwhile! ๐Ÿ’šGrowers Love!๐Ÿ’š๐Ÿ˜Ž๐Ÿ™

Plants are doing well. Watering roughly once weekly continues to be the current schedule. In this week's watering (week 6, Thursday), a nutrient mix was added (19% Nitrogen, 5% Phosphate, 20% K2O). pH was measured (via the runoff/drainage water collected) on all three plants using a pH probe, of which was measured to be slightly acidic for all plants (exact pH numbers above in the photo descriptions). We are aiming for a pH range of 6.0-7.0, so in next week's watering, we will add a buffer solution to alkalize the soil. All three plants lower branches were also pruned.

This is the final week of nutes for the ladies! Time to flush her for the coming week. Also read that Purple Punch needs cold temps at night to turn color. Since I can't do that where I live, an alternative is to flush her with ice water. Giving that a try and will keep you guys updated.

Week three, in the ground hardening in the elements. Growing in severe drought conditions is a challenge, but having a dog who wants to eat the tops off my plants is another challenge. He's only done it this once and while I am working in the garden, other than that he leaves them alone. So one plant is super cropped, thanks to my dog. The other two are left alone so far. I will be doing some LST on two of them. The purple colors are already beginning to show in the stems and leaves, the plants are building a solid stem base. I think most of that is from the genetics and hardening in the windy conditions I have here. I'm watering twice a week just to keep the soil from drying out. I'm excited to see these girls develop and produce some awesome colors. I love purple weed.

What's in the soil? What's not in the soil would be an easier question to answer. 16-18 DLI @ the minute. +++ as she grows. Probably not recommended, but to get to where it needs to be, I need to start now. Vegetative @1400ppm 0.8โ€“1.2 kPa 80โ€“86ยฐF (26.7โ€“30ยฐC) 65โ€“75%, LST Day 10, Fim'd Day 11 CEC (Cation Exchange Capacity): This is a measure of a soil's ability to hold and exchange positively charged nutrients, like calcium, magnesium, and potassium. Soils with high CEC (more clay and organic matter) have more negative charges that attract and hold these essential nutrients, preventing them from leaching away. Biochar is highly efficient at increasing cation exchange capacity (CEC) compared to many other amendments. Biochar's high CEC potential stems from its negatively charged functional groups, and studies show it can increase CEC by over 90%. Amendments like compost also increase CEC but are often more prone to rapid biodegradation, which can make biochar's effect more long-lasting. biochar acts as a long-lasting Cation Exchange Capacity (CEC) enhancer because its porous, carbon-rich structure provides sites for nutrients to bind to, effectively improving nutrient retention in soil without relying on the short-term benefits of fresh organic matter like compost or manure. Biochar's stability means these benefits last much longer than those from traditional organic amendments, making it a sustainable way to improve soil fertility, water retention, and structure over time. Needs to be charged first, similar to Coco, or it will immobilize cations, but at a much higher ratio. a high cation exchange capacity (CEC) results in a high buffer protection, meaning the soil can better resist changes in pH and nutrient availability. This is because a high CEC soil has more negatively charged sites to hold onto essential positively charged nutrients, like calcium and magnesium, and to buffer against acid ions, such as hydrogen. EC (Electrical Conductivity): This measures the amount of soluble salts in the soil. High EC levels indicate a high concentration of dissolved salts and can be a sign of potential salinity issues that can harm plants. The stored cations associated with a medium's cation exchange capacity (CEC) do not directly contribute to a real-time electrical conductivity (EC) reading. A real-time EC measurement reflects only the concentration of free, dissolved salt ions in the water solution within the medium. 98% of a plants nutrients comes directly from the water solution. 2% come directly from soil particles. CEC is a mediums storage capacity for cations. These stored cations do not contribute to a mediums EC directly. Electrical Conductivity (EC) does not measure salt ions adsorbed (stored) onto a Cation Exchange Capacity (CEC) site, as EC measures the conductivity of ions in solution within a soil or water sample, not those held on soil particles. A medium releases stored cations to water by ion exchange, where a new, more desirable ion from the water solution temporarily displaces the stored cation from the medium's surface, a process also seen in plants absorbing nutrients via mass flow. For example, in water softeners, sodium ions are released from resin beads to bond with the medium's surface, displacing calcium and magnesium ions which then enter the water. This same principle applies when plants take up nutrients from the soil solution: the cations are released from the soil particles into the water in response to a concentration equilibrium, and then moved to the root surface via mass flow. An example of ion exchange within the context of Cation Exchange Capacity (CEC) is a soil particle with a negative charge attracting and holding positively charged nutrient ions, like potassium (K+) or calcium (Ca2+), and then exchanging them for other positive ions present in the soil solution. For instance, a negatively charged clay particle in soil can hold a K+ ion and later release it to a plant's roots when a different cation, such as calcium (Ca2+), is abundant and replaces the potassium. This process of holding and swapping positively charged ions is fundamental to soil fertility, as it provides plants with essential nutrients. Negative charges on soil particles: Soil particles, particularly clay and organic matter, have negatively charged surfaces due to their chemical structure. Attraction of cations: These negative charges attract and hold positively charged ions, or cations, such as: Potassium (K+) Calcium (Ca2+) Magnesium (Mg2+) Sodium (Na+) Ammonium (NH4+) Plant roots excrete hydrogen ions (H+) through the action of proton pumps embedded in the root cell membranes, which use ATP (energy) to actively transport H+ ions from inside the root cell into the surrounding soil. This process lowers the pH of the soil, which helps to make certain mineral nutrients, such as iron, more available for uptake by the plant. Mechanism of H+ Excretion Proton Pumps: Root cells contain specialized proteins called proton pumps (H+-ATPases) in their cell membranes. Active Transport: These proton pumps use energy from ATP to actively move H+ ions from the cytoplasm of the root cell into the soil, against their concentration gradient. Role in pH Regulation: This active excretion of H+ is a major way plants regulate their internal cytoplasmic pH. Nutrient Availability: The resulting decrease in soil pH makes certain essential mineral nutrients, like iron, more soluble and available for the root cells to absorb. Ion Exchange: The H+ ions also displace positively charged mineral cations from the soil particles, making them available for uptake. Iron Uptake: In response to iron deficiency stress, plants enhance H+ excretion and reductant release to lower the pH and convert Fe3+ to the more available form Fe2+. The altered pH can influence the activity and composition of beneficial microbes in the soil. The H+ gradient created by the proton pumps can also be used for other vital cell functions, such as ATP synthesis and the transport of other solutes. The hydrogen ions (H+) excreted during photosynthesis come from the splitting of water molecules. This splitting, called photolysis, occurs in Photosystem II to replace the electrons used in the light-dependent reactions. The released hydrogen ions are then pumped into the thylakoid lumen, creating a proton gradient that drives ATP synthesis. Plants release hydrogen ions (H+) from their roots into the soil, a process that occurs in conjunction with nutrient uptake and photosynthesis. These H+ ions compete with mineral cations for the negatively charged sites on soil particles, a phenomenon known as cation exchange. By displacing beneficial mineral cations, the excreted H+ ions make these nutrients available for the plant to absorb, which can also lower the soil pH and indirectly affect its Cation Exchange Capacity (CEC) by altering the pool of exchangeable cations in the soil solution. Plants use proton (H+) exudation, driven by the H+-ATPase enzyme, to release H+ ions into the soil, creating a more acidic rhizosphere, which enhances nutrient availability and influences nutrient cycling processes. This acidification mobilizes insoluble nutrients like iron (Fe) by breaking them down, while also facilitating the activity of beneficial microbes involved in the nutrient cycle. Therefore, H+ exudation is a critical plant strategy for nutrient acquisition and management, allowing plants to improve their access to essential elements from the soil. A lack of water splitting during photosynthesis can affect iron uptake because the resulting energy imbalance disrupts the plant's ability to produce ATP and NADPH, which are crucial for overall photosynthetic energy conversion and can trigger a deficiency in iron homeostasis pathways. While photosynthesis uses hydrogen ions produced from water splitting for the Calvin cycle, not to create a hydrogen gas deficiency, the overall process is sensitive to nutrient availability, and iron is essential for chloroplast function. In photosynthesis, water is split to provide electrons to replace those lost in Photosystem II, which is triggered by light absorption. These electrons then travel along a transport chain to generate ATP (energy currency) and NADPH (reducing power). Carbon Fixation: The generated ATP and NADPH are then used to convert carbon dioxide into carbohydrates in the Calvin cycle. Impaired water splitting (via water in or out) breaks the chain reaction of photosynthesis. This leads to an imbalance in ATP and NADPH levels, which disrupts the Calvin cycle and overall energy production in the plant. Plants require a sufficient supply of essential mineral elements like iron for photosynthesis. Iron is vital for chlorophyll formation and plays a crucial role in electron transport within the chloroplasts. The complex relationship between nutrient status and photosynthesis is evident when iron deficiency can be reverted by depleting other micronutrients like manganese. This highlights how nutrient homeostasis influences photosynthetic function. A lack of adequate energy and reducing power from photosynthesis, which is directly linked to water splitting, can trigger complex adaptive responses in the plant's iron uptake and distribution systems. Plants possess receptors called transceptors that can directly detect specific nutrient concentrations in the soil or within the plant's tissues. These receptors trigger signaling pathways, sometimes involving calcium influx or changes in protein complex activity, that then influence nutrient uptake by the roots. Plants use this information to make long-term adjustments, such as Increasing root biomass to explore more soil for nutrients. Modifying metabolic pathways to make better use of available resources. Adjusting the rate of nutrient transport into the roots. That's why I keep a high EC. Abundance resonates Abundance.

Second week of flowering in the bag, and theyโ€™re all looking really healthy, even healthier than when I first threw them in the flower steady as she goes
