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 0.8–1.2 kPa 80–86°F (26.7–30°C) 65–75%, 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.

Flo 15: Arrosage engrais complets Flo 16: Défoliation des gourmands

Activaron 24hs en un vaso de agua sin cloro. Luego al tupper con papel (rollo de cocina). Luego de 3 / 4 días ya se pasaron a tierra. En los primeros días y luego, en toda la etapa vegetativa vamos a usar un humidificador para tener una humedad entre el 70% y 80%

Both plants are thriving. The mimosa still growing fast despite the fact it was burned by the light. The bourbon berry is trying to keep up with the mimosa plant.

I added another 4 tablespoons of pridelands bloom top dressed after defol. Still watering in brix, green aminos, armor si, calmag and great white everyday till max saturation

🌱 Day 50 - First Day of Week 8 🌱 Hello, Grow Friends! My plant is doing well, and it’s amazing to see visible progress every few hours. 🌱✨ The buds are in full throttle, and I feel like the plant is now needing more water as the pots are drying out faster. 💧 Watering: I’m still watering with 1L every two days. 💦 The dosage of BioBizz Grow and BioBizz Bloom has been increased according to the BioBizz feeding schedule. The pH of the water remains constant at 6.0. ⚖️💧 Temperature & Humidity: Luckily, the weather in Germany is cooling down, so I no longer have to deal with temperatures of up to 30°C in the tent. 🌡️🍂 I’m expecting temperatures to settle between 18-23°C now that we’re in September, and humidity should stabilize around 50-55%. This will create perfect conditions for the upcoming drying process. 🍃✨ Plant Health: The plant is looking good overall. 🌿 I did have some calcium and magnesium deficiency symptoms recently, but I’ve managed to get that under control with CalMag. 💪 I’m continuing to carefully remove any leaves that are noticeably blocking light to the buds and hindering photosynthesis. 🍃✂️ Vibes: Every day, my plant still enjoys an hour of Lo-fi Jazz music. 🎶🌱 I think it helps set the perfect growing atmosphere. 🎷 🌱 Day 56 - Last Day of Week 8 🌱 Final Feeding: Today marks the last day of the fourth flowering week and the last day I’ll be feeding the plant. 🌿💧 From now on, the plant will receive only water for the final 14 days to flush out the remaining nutrients from the soil. 🚿 As a beginner, I’m unsure if two weeks without nutrients will be enough for the plant to finish properly. There’s a part of me that worries about potentially wasting its full potential by skipping nutrient periods. 🤔🌱 However, I’ve decided to stick with the plan—after 14 days of just water, I’ll harvest the plant. ✂️🍃 Humidity & Temperature: This week, the weather has cooled down significantly, and I no longer have to struggle with high temperatures. 🌡️🍂 The temperature ranges from 19-23°C during the day, and humidity sits between 49-56%. I think these are ideal conditions to bring out the purple hues in the buds. 🍇✨ Defoliation & Plant Care: I’ve finished the final defoliation and trimming of the plant this week. 🍃✂️ From now until harvest, I’ll avoid making any more changes or interventions, as I want to keep the plant stress-free and allow the bud production to progress smoothly. 🌱💪 Trichome Observation: As a beginner, I’ve started checking the trichomes this week, but I’m finding it challenging to distinguish between clear and milky trichomes. 🔍💎 I plan to harvest when I see 90% milky and 10% amber trichomes. 🌿✨ I’ll keep you all updated next week, and don’t forget—there are new pictures every day! 📸🌱

Que pasa familia, traigo la 2 semana de esta farm cheese, la verdad que se está comportando muy bien y el alimento aportado de advanced nutrients como siempre lo agradecen. Ph controlado, temperatura y humedad dentro de los parámetros, ya quitamos el propagador y ya es esperar hasta que cojan altura para pasarla a floración. web: http://bit.ly/2uJAjgy ts600: http://bit.ly/3cnv0Ev code: an420 Nos vemos la semana que viene fumetillas

TThis week I decided to move from my small ass bedroom and pre fab me a area in my nice ass basement with great element and ceiling. I'll have a couple little videos. Still not done revamping that spot. But I'm hanging 3 mars hydro I just ordered from my beautiful rafters. Lay some mylar and a platform of a sort. Use some reflective tarp to outline my space. Switch out the basement lighting with 3 green led lightbulbs. 24/7 access to obsession. You're welcome. Still got the 4x4 pulled up there so everything is accessible. check in later

Shortly after they were switched to flowering (after week 3) the plants continue to stretch and then start to develop their first flowers. Now in week 7 all plants have very nice flower clusters all over the plant and side branches. They have grown to 45 cm (=Shiva Skunk on left side) and 40 cm (Serious Kush on right side of aisle) in height respectively and all plants have a nice dark green color, which shows they are healthy and also that the Advanced Nutrients schedule works like a treat. The Q6W-Gen.2 LED-Lamps are now dimmed to 100% (=three green LEDs on the dimmer) and work on FULL POWER, which ensures full fledged flower production. Both varieties have now started to exude their typical aroma. The Shiva Skunk starts to smell musky and sweet, while the Serious Kush smells 'gassy' and 'fuely' like its OG-Kush heritage. The flower clusters on the Serious Kush appear to grow denser than the clusters on the Shiva Skunk.

Had a bit of strip not much to say about this week again apart from flowering is happening finally and it's getting there with small bud sites popping out everywhere

21.4. začátek 4. týdne - proběhl gangbang Shamana se Shamankama (viz video) - nikdy jsem neviděl samce kvést a je to masakr kolik pylu docela malá rostlina dokáže vyprodukovat - pestíky holek už jsou hnědý/zrezivělý, tak snad se povedlo a nějaká semínka budou - opylení Widow grail bude trochu víc kontrolované, ty teprve začnou kvést, proto jsem si část pylu schoval do lednice - zatím vypadá všechno v pořádku

Esta variedad me encanta, huelen genial y sus cogollos son super densos y llenos de resina siempre. Poca tolerancia a los excesos y es muy fácil de estresar. A pesar de todo sigue siendo una de mis variedades favoritas ya que su aroma old school con toques ácidos me fascina!. Actualizaré luego del secado y después notas de humo. Saludos!

Will be harvesting today or tomorrow. After one week of flush, I stopped every watering since the start of this week. Now there’s less water inside the pot, and I can definitely feel it by moving it around. Buds are visibly bigger now! See you soon for the final harvest!

Week is going good aside from me accidently cutting off a stem on pheno 2. If I can properly save the cutting though I might have a chance at another female. Pheno 3 I'm hoping can make some comeback as I really want to flower the plant, its not dead by any means but the way its growing I just cant see it allowing itself to flower the top leaves were barely growing so I topped. Hopefully positive changes within the next week.
