Total days above ground: 63 Total flower nights: 24 Just beyond 3 weeks into flower and the plants are showing their potential. The Mountaintop Mint has made great strides but is still a lanky bitch. I had to HST every branch, and may need to bend a couple more down before vegetative growth abates. Not a fan of this growth pattern and still unhappy about 2 out of 9 seeds providing a viable outcome. The bright side is that yield should be fine given the plethora of bud sites. Despite being difficult to grow next to other plants, I feel much better about its prospective outcome than I did just 1 week ago. That whole "crazy shit can happen in flower" thing rings true, again. Overall the canopy has filled in nicely. I have a couple spots where light is wasted and I'll make some adjustments to the process to fix that for future grows. Now that I've settled on plant size and number of plants, improvements can be made each cycle until it's clockwork. I like the 12-cola vs 8 cola experiement. I've got a fairly long list of edits to make to various sections of my "bible," which means I liked the outcomes of most of my incremental adjustments. Continual, systematic improvement in action... One other incremental change on the docket but not yet realized will be dropping nutrient concnetration once vegetative growth ends. Exact timing will be based on what I see in the foliage. I see some minor tip curl and its a bit darker than I want. So, it may come sooner than later. This'll be something I tweak over the next few grow cycles until I'm happy with the late-flower health. I'll drop fertilizer concentration 10-15% on next refill and see how that plays out. It'll take a couple refills of reservoir to near 100% transition without draining it. If necessary, I'll drain and do a full refill for more pressing needs. A rez scrub before final stretch is coming, regardless. Side note: The impacts of VPD can be enormous. Last year (2025-2 diary) I had a humidifier wick get fouled and RH dropped while VPD spiked for more than a few days, thinking I could power through or that the canopy would soon provide more moisture. Nope, growth stalled in a significant way. By comparing day 34-42-49 of 2025-2 and day 38-42-49 of this diary, I can see a huge difference in growth at same point above ground. The consitency with which i do things makes it fairly certain it's the extende period with extremely high VPDs that caused the difference. Also, interesting that it mostly catches back up by completion of third week of flower. The size difference is nearly undone by this point, though 2025-2 took 4 days longer vege phase to get there. Even so, I still think this grow is more than 4 days ahead of 2025-2 (the difference in vegetative phae duration). Time will tell if the development is ahead of the pace in 2025-2 or whether it's simply mostly an offset due to a less efficient vege phase for 2025-2.

Was going to try and do some LST clips the first week but ended up breaking the main stem of the one of the Critical girls and just said screw it, I’m gonna top then all now. Did a feeding (2 gallons total) of 1-5-1-3 with CalMag and the GH Trio. 12 hours after topping/feeding and they are all recovering nicely. Did a second feeding (2 gallons) of 1-5-1-3 with CalMag and the GH Trio midweek. So far no signs of nutrient lock or burnt tips. Couldn’t get home to do a third feeding. Going to be keeping the girls in veg for another week or two.

We are reaching full maturity slowly but surely. The pheno on the left is a solid week ahead of the one on the right. They are finishing quite differently. The left has reached full color showing yellows and purples about 12 days ago. Her velvety flowers a plump and juicy looking and remind me of a sour candy. The one on the right is showing signs from the flush but calyx swell and trichrome production has yet to peak. The smell is intense and even slightly different then the critical Kush I've experienced in the past. Pheno A will be harvested this week I'm guessing. Watching trichromes day to day at this point. I like just a bit of amber.

Sooo the girls stretched heavyyyyyyyy many many budsites and a 4x4 thats not only filled in the width but also almost in the height😂. Im just in love with the grow so far. Thirsty like a mf, they went down on 20L in 48hours so about 3.3L per day for ONE plant. About 18 days since I flipped so I think the last 3-5 days of stretching before its finally over. Did a good lollipop and defoliation on them below the net so enjoy the view!

Buenas a tod@s... Otra semanita para estás nenas, como ya sabía a estás niñas lesva a faltar algo más de luz y sobre todo tiempo, para el tiempo q las tengo es verdad q ko crecieron mucho, ya q tengo bastante limitado el sol en la casa, pero ahora ya estuvieron y van a seguir algo más cerca de los focos, de momento salvarlas y ver q crezcan y no pretender tanto de ellas, serán lo q serán hasta q las vuelva a poner en indoor.. se las ve bien igual, van a su tiempo... Un saludo y buenos humos... 🏻🙌🏻💪🏻👍🏻

Servus Moin! Mit der MDC Fern #3 bin ich bis jetzt am meisten zufrieden! Die unteren Triebe zeigen deutlich guten Wuchs und holen sicher die 2 oberen Triebe noch ein. Von den Stecklingen ist sie als erstes angewurzelt und wächst schon freudig weiter. Starker Pheno. Obwohl ich erst skeptisch war.

At the end of the second week of bloom the Dough Boy feminised is doing well with no signs of deficiency. Her leaves are a stable green the stem is a healthy pale green and she has grown a stable 8cm. There’s signs of bloom with white stigmas appearing and she will receive feeding as required. Caution is needed until the lady consumes more! The Dough Boy feminised stands at approximately 58cm ta

Decided to flip to flower this week. Ramped up to 1.1 ec before flipping. Probably a tad too slow since they look hungry. Will slowly increase. Did some more LST to widen them up a more during the stretch. .

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.
