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.

I mean, overall this was an extremely painless grow. The test of whether we should or shouldn't top autos is still TBD imo. Our topped candidate produced denser, frostier buds, but weighed slightly less, at 14 grams of bud total. And our lst plant produced 18 grams of bud, not as frosty, and almost as dense as our topped girl. I'll be topping autoflowers from here on out only under the circumstance I have 4+ to grow at the same time. Seems like it could be used to speed up the autoflower grow cycle if done properly, like with right. Since I'm doing a perpetual cycle, it's still a viable option for me in the long run. A few tips I have for anyone growing this strain in organics: Start feeding bloom nutes a little bit prior to flower transition - this makes the transition more seemless. From weeks 1-3 flower, I slowly dropped the grow dosage until I cut off grow nutes week 3 flower. Starting the flush around week 6 flower seemed to really bring out this plant's potential. But I think you could get away with starting the flush around week 5. I hope this helps anyone trying this strain out. It's a good one, I hope to see more journals of it, eventually. Cheers everyone! Time for me to take a well-deserved puff. :) ☁️ 🌼

Just feed her ph water for the last couples of days I’ll be chopping her down this week due to heat wave in my area .. wish I could let her go few more days At this stage she’s releasing nitrogen still

Week one our first grow wish us luck and any advice is much appreciated

This plant seems to have grown much denser and better than my first plant. I just got the ac infinity ventilation setup with controller 69 for my 2x2, still trying to learn, hopefully grow #3 goes even better. Stay tuned

GENERAL COMMENT. WEEK 5 OF FLOWER. Ok guys, this week ran ok for one girl and less for her sister, so i will go on details individually. RQS NORTHERN LIGHTS AUTOMATIC COMMENT. As I has commenting since the beginning I think this could be a nice strain to grow with minimal water and nutes, keep that in mind when growing this strain, i learned the hard way. What happened with this girl is that salt builded up in the medium and de stabilised mainly the PH, creating a super acidic medium, thats my bad, i failed to id earlier. So back to spotting, and a bit of yellowing showing, so some deficiencies, i honestly don’t know how this is going to end. I flushed her 4 days a go with PH water to 6.5, that raised the medium runoff from 5.0 to 5.4-5.6, and flushed again with tap water, is alkaline at 8.1+, runoff is still 5.6, so that raised more concern with that input range getting so acidic runoff is bad, and in the end of flush received a dose of voodoo juice, big bloom, calmag and top candy, that are all organic at regular ph, EC at 1.8. I know the PH fluctuation can worse the scenario. I’m been apocalyptic is just that i’m feeling a bit turn down now, i was expecting this girl to run flawlessly, heads up will try my best to correct issues, just wished she was like her sister…

Plant has solid root base

Cut down wet weight 721 g :)))))) Bottom half to do in a week or two:)))) will up date all in harvested week first weigh in 165 g :))))

BOOMING. Have had an unusual amount of thrips and noticed a few Katydid nymphs on Tuesday (7/22), so I hit everything with 1.5tsp Neem Oil and 1 tsp of Dr Brommers soap in a 1 qt sprayer. I also decided to do my only planned dusting of Diatomaceous Earth. Executed that on Wednesday, 7/23, and also top dressed with DE to attack larvae. Thursday 7/24 Mixed up first batch of flowering top dressing. I put it into a 55 gal garbage can and watered it to get the cooking process started. Will only let it go for a week or so and then will top dress the girls.

Another nice cola forming

Final Week – Late Flower The final week was essentially a clean finish to the run. The buds swelled further, becoming dense and well structured. Despite the ongoing mildew issue, the situation remained controlled and never spiraled out of hand. Lowering nighttime humidity below 50 % clearly helped slow down further spread. The focus was on maintaining stable conditions and consistently removing affected leaves. Overall, the positives clearly outweigh the negatives: strong plants, solid bud development, and very relaxed handling thanks to Biotabs and the automatic irrigation system. Now it’s simply about finishing strong and harvesting.

Still not given any food. It will be a few weeks until she needs food as I've just put her into a 4 ltr pot 👍

26.07. Girl Scout Cookies Day 92# GSC is progressing well, it has slowly started to spread. Yesterday was the end of its thirteenth week. It is currently raining, there will be some storms in the next 2-3 days and rain in the next 4-5, so it will cool down a lot and the next 10 days will be quite normal weather, although the nights will not be very great. Stay High and Keep Growing!!!

Week started how I hoped. Rain stops and the sun is shining several hours per day. But it is still cloudy often.

This week went pretty well, other than she stretched like crazy and I am now getting worried about running out of vertical space. I also had a few of my bottom leaves get a few brown and yellow spots on them. I did post some pics and asked a question, thank you for the responses, much appreciated! I am thinking about adding my Spyder Farmer LED 100 Watt light into the tent for the nebula auto because it is about 23 inches shorter than the sour diesel. I believe it would only raise my temp about 2 degrees, and possibly lower the humidity by one or two percent. I must say my dehumidifier has been a freaking stud, running 24X7 and not complaining. I should look into adding another unit, it has been in the mid 90's and muggy for about a week. So far I have to say I am super impressed and excited with this setup, the genetics, and with growing this wonderful plant in general. Already planning ahead to my next grow, and what I can do better. I have been enjoying myself and I really appreciate everyone who has taken the time to answer my questions! I am having a blast and am excited to see what this lady will give up in a few weeks!
