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.

Hello growmies 👩‍🌾👨‍🌾🌲🌲, 👋 The babies keep growing well. The burned has been recovery, Still the mutation on the #1, since the 3rd nodes, she's doing 1 leaves instead of 2 per nodes, really strange, maybe I could recover with toping and hoping the secondary stems will develop 2 leaves per nodes. Starting nutes and give more and more water. 💪 No Training for the moment, just let Grow. 💧 Give water each 2/3 day And vaporise plant with water + Plagron Roots (1ml/l) 0.25 l Water + Roots + Grow (1 + 2 ml/l) 0.25 l Water + Roots + Grow (1 + 2,5 ml/l) 0.4 l Water + Roots + Grow (1 + 3 ml/l) PH @6 💡Mars Hydro - FC 3000 50% 77 cm.

🧐🙄🌱🍃🐊🐛🌞🐤

Im so loving this strain ! Smells so goooood!! Did a last watering with Dense by GP Im really loving this stuff!! Check my IG account for a giveaway @Frosty905budz The flushing has begun Flushing with Flawless finish by Advanced nutrients [email protected]

She’s growing fast. Developed some CalMag issues this week but she perked up after a bit of silica and CalMagic. Flowering has begun as of the 14th (day 18 of the grow roughly. Roots are looking good.

09/26/2020 She is almost done, I gave her a little trim most trichomes are milky still some clear I think about a week before she is done. Hope she gets fat!

: End of week #6, and I’m extremely happy with the results so far, especially considering the conditions inside the tent — it’s quite small with limited airflow. The plants are in full bloom and still bulking up nicely. A strong aroma is starting to fill the space (my roommates are already complaining about the smell!). I’ve been following the BioBizz feeding schedule to the letter, carefully keeping the pH between 6.3 and 6.5, and watering every other day without skipping nutrients. As shown in previous weeks, my RHC #2 has become the tallest plant, and it’s clearly the one that will produce the biggest and fattest colas. RHC #1, on the other hand, is denser but its colas aren’t as large. Overall, I’m very pleased with the progress and now eagerly waiting for the moment to start the drying process. I assume that eventually the colas will start turning red, although there’s only about a 60% chance of that happening. RHC #1 is already showing some color on its leaves, which is a good sign. Once it’s fully mature, the colors should become more intense — hopefully shifting into a deep, vibrant red. I’m really looking forward to seeing that transformation take place as the plants reach their final stages. 😍

They are doing great including the 1 that got ate she is now the baby of the bunch... The other 1 that had burnt leafs also seem to be growing showing new growth.. And the other 1 is 16 inches she is outgrow everything in tent lol... I love growing cannabis

Here we are with the papaya bomb!!! Lets go! I did some serious defoilation coming into this week! You can see the healing from the Hst, and Lst I've been using. I had a really busy week last week and wasnt able to update! Argggg I always feel bad when I dont! But its okay we are here! She is doing great looking strong and getting stronger day by day! Im looking to make the flip to 12/12 in about 1 more week! I dont wanna push this plant to be too big as she is only in the 2x2. I have intentions of focusing on a few main coals! Try to get em big outta the living soil bed! Learning a lot on living soil while all organic! Any tips tricks let me know

Settling in after transplanting loooking lush green and healthy maybe another two weeks of veg

Another slow week. I increased light schedule to 13/11. I’m going to slowly lower the time of light until by the time harvest day comes it’ll have a longer dark period. I’m also going to stop feeding the bottle nutrients my soil is moist still so I gotta wait. I’m predicting a couple ounces this grow.

Things are getting dense and kind a wild 😜🤩😅 but all looking as it should 😊 They are stretching and with the colors we want for this fase, I’m trying to get to day 20/21 for mass defoliation, but if they keep growing like this i think sooner than that my hands will be all over them 😈😇 let’s see how they evolve and grow 😌 For now i’m keeping my vpd at 1.1kPa, my ppfd around 700 uMol/m2/s this gives me more or less a DLI of 27.72 , my Co2 is at 850ppm 5x White Mango 5x Alasken Purple 4x Blueberry 3x SAD S1 3x Badazz Cookies 10 in total for a 4x8x6 - 1,2x2,4x2 Light Lumatek Zeus 465W compact pro 2x at 100% All i Grow is medicine for myself, Stay safe, stay tuned and B Happy and do it for the love Peace ✌️ D

Week 2 into flower and she is doing well. Lots of bud sites! Dropped the light to 13 inch, around 800 PPFD. RH is around 40%. I gave her 2 L of water and green rush nutrients. Nothing much. Happy Growing!

5 week have already passed since the start of the flowering stage. The stunned auto is healed and growing happily and strong with 40cm Both green poison are already really sticky and with lots of the good sugar. The smell is getting really strong too and the buds are going big and fat. Plant height: 40cm The critical + 2.0 are the ones with the strongest smell, but the shortest too with 35cm. The good thing about them is the 14/16 tops they have Finally the skunk 47 wich was an offer and at the beginning, the slowest growing but became the tallest with 45cm. Strong, fruity smell and long and dense buds. Just did the last defoliation on every girls, nothing too heavy and introduced the Plagron Green Sensations. Tell me what you think guys! See you next week 😎

17.3.25: So I watered with 2ltrs of dechlorinated water PH'd to 6.4 with 4ml Xpert Nutrients Cal-Mag amino acids. I have really overdone the nutrients, I got carried away 😅 To try and rectify the situation, I've cut everything out except Cal-Mag amino acids. I will try to just stick to this with some Biosys, but I'm running out of that now, too. Anyway, with Or Without, I'm sure it'll balance out. Fingers crossed 🤞🌱✌️💚 21.3.25: The plants are all getting plain water PH'd to 6.4. I have removed all nutrients and water every plant 1-2 litres daily. I would probably have continued using the Xpert Nutrients Cal-Mag amino acids. However, the NPK is 4-0-0. So, whilst it's great stuff, I don't need the extra nitrogen. I add Ecothrive Biosys to some of the waterings. Unfortunately, I have very nearly run out. So I'm using it on selected plants, which I think could use a bit of TLC. I checked the soil PH of all pots, and it was bang on 7.0 for each one. Substrate temperature was 19°C across the board. The soil moisture meter said the soil was dry in every pot: I chalk that up to being my medium, as it's very aerated and of low density. Also, I never water to run off. So I'm unconcerned about that. All being said, I'm hoping to see some of the plants stored nutrients be tapped into and try to balance things back out. They definitely have had a little too much feed. It does seem like apart from the leaves, they are all looking great! The plants are drinking heavily, and I watered 4ltrs to Do-sì-dos, 2ltrs to Pink Mist, 3ltrs to Bubble Kush, and 3ltrs to Gorilla Cookies. The pots had already completely dried out. So I'll definitely have to up my waterings. The colas are getting fatter, and ripening up slowly. Thanks for hanging out 🍃 ✌️ 💚 🙂

3rd week of flowering started and for only 2 weeks of flowering these ladies have grown very well. I had to pull my lamps even higher which the plants definitely enjoyed. they all gained about 10cm height in less than a week. I added some CalMag to my water just prevent deficiency. I usually do it around week 9-10

Super busy with a move and a big garden reno. Sorry, this is the only update for this week
