OK so we are at day 57 and wer flowering. Looking nice and tall and green. Can't wait for the buds to come. Not bad just tap water and watered down coffee grounds once a week. https://home.howstuffworks.com/green-living/use-diluted-coffee-to-fertilize-plants.htm#:~:text=A%20weak%20solution%20of%20coffee,on%20the%20left%2C%20is%20perfect.&text=Don't%20just%20pour%20it,green%20growth%20and%20strong%20stems.

my 2 Allienz seem to be hermaphrodites :/ I had to stress them in different ways. The first weeks I sprayed the leaves leaving drops under a 400w light maybe this caused the hermaphroditism? Anyway I'll be careful and I'll be cleaner for my next future culture. --------------------------------------------------------- Grow Room: trafika urban hydroponics 100x100x200 cm Lamp: kit trafika urban hydroponics ballast & lampe HPS : 250-600w Extractor & carbon filter : Mars hydro 6 inch 402 CFM ( power 3/10 ) Soil : 20% perlite, 20% vermiculite, 60% universal soil Average daily temperature & humidity : 20-29°C 35-60% Average nigth temperature & humidity : 12-18°C & 50-70 %

All feeds with nutes use either a whole ratio or combination of "Veg Mix" and "Bloom Mix"concentrates DILUTED in water until a total ppm of add in is reached using a (Total Dissolved Solids)TDS Meter measured in PPM (parts per million). The "Veg Mix" concentrate will eventually be added in smaller ratios and "Bloom Mix" concentrate what will eventually replace the "Veg Mix" concentrate entirely with the ppm and ratios listed when I feed. Veg mix recipe is on week 3. Bloom Mix recipe is on week 5. 84/14 Fun with Filters VPD was controlled at reduced temps and RH today - RH now set to 55% max and Temps are 75F at max Over night allowed down to 67F when lights go out. Lights were good and same as yesterday with some light LST PPFD at 750 down to 550. I used 20 minutes of UV and 1 hr of IR with 15 before and after main lights on/off. She's now about 25" tall and 35" wide. Also took some black back and shadow pics for fun (no filters or sharpen only) Day 85/15 Feed Day I gave 2 gallons of de-chlorinated tap combined with 25:75 Veg/Bloom mix total 600ppm and a ph of 6.4. Foliar sprayed some on the outer leaves and left the tent door open to help dry them. (took like 15 minutes with the fans.) top soil ph checked at 6.22ph and run off was at 5.74 with 1580ppm Lights at a range of 750 to 500 Ran 25 minutes of UV and the standard 1hr IR with 15/15 before and after lights on/off and 30/30 at that time. VPD was easy to manage with the doors open and then the fan seemed to have to work more today but just more often and not high fan. Day 86/16 Humidity was high at 60%RH for most of the day, the ILV was kicking on throughout the day and I have two humidifiers going on high. Temps on the other hand was controlled at about 74F. Tips carried a little burn on them today, some all over which makes me think nute burn because ppfd was 550 to 750 as it has been for a few days now and there are tips on leaves with little direct light showing burn as well. Will continue to monitor as well. IR and UV are set on timers and I screwed up with mine today. I was supposed to change the setting and forgot (time change screwed me up and I thought I did it when I changed timers that needed correction) until it was too late and ended up giving her 30 minutes of IR and 1 hour of UV... will have to check/monitor for effects tomorrow. The good news is that she's had a little over two weeks with UV so maybe not so bad. (fingers crossed it doesnt stress her too much) Day 87/17 Again, humidity was high at 60%RH for most of the day, the ILV was kicking on throughout the day and I have two de-humidifiers going on high. Temps on the other hand was controlled at about 74F. If I open the tent for a while I can get the humidity down by about another 5% so tomorrow I plan to leave it open after I feed again. Took some light burn from yesterday's extended UV exposure, but read that it's not bad to take on some stress from UV in flower, especially if you still have time to recover. The pros suggest that you can stress her to grow defensive systems that may create thicker/stickier leaves and flowers with more terpene production. The cons however suggest that it could stress too much and stunt the growth or in extreme/sudden cases, cause her to herm. (thus why they say in mid flower is best if you plan to stress with UV) So it is what it is. I will monitor the leaves that took damage and likely remove them this week when I defoliate schwazz style. I still resumed the schedule of increasing UV as planned but ahead a few days now so 45minutes of UV and 1 hr IR with 15/15 before and after main lights on/off. Day 88/18 Lots happening today. Firstly, I found a split today... on the main stem trunk, so I used superglue to seal the cracks and held together while it set. Then I wrapped it with heavy duty gorilla tape, two 1ft pieces as both a clamp and a support on the other side. I then tied each cola to the inner ring. So then I decided that since I am here having to work on this I may as well go ahead and do the defoliation I was planning for tomorrow. Schwazze style defoliation (at least my interpretation of the method without having to buy the book, super defoliate week 1 and 3 of flower - so almost) Then after that I also preformed heavy strength training - I broke each cola right under the bud sites that I left and bent her outward. I then upped the lights ever so slightly and have a max of 850 ppfd and low of 650 ppfd now. She had 45 minutes of UV and 1 hr of IR same routine, IR on/off at main light schedule with 15 before and after main lights. VPD is better now that I placed another open air vent at the bottom, this one is 6 inch. I also placed the fans a little better to blow directly on the leaves left behind. Low speed for now, but as the leaves come back I plan to increase to get dancing leaves in the middle too. Temps were 74F and RH 55% with the ILV set to auto. I plan to feed 2 gallons of 650ppm 25:75 Veg/Bloom mix. Since my last ph was really low I am going to increase the feed to 7.0ph - not sure what if anything I can do about ppm. Day 89/19 VPD was normal with the exception of holding the tent open as I said I was going to today. Temps at 74F and RH mostly 55% with the ILV set to auto. PPFD also checking in with the same settings/results today, 880 to about 650 ppfd. UV was set for 45 minutes midday, and IR with the same 1 hr with 15 minutes before and after main light on/off. Water feed today with about 2.25 gallons of 7.0 ph de-chlorinated tap diluted with 25:75 ratio of veg/bloom mix (690 ppm total) watered until drip started and I got about .25 gallon runoff. Runoff measured 5.75 ph and 1630 ppm (top soil tested 4x with avg of 6.35) Next feed will be a plain water salt flush. Plant looked so nice a day today that I decided to take some more black back pics. Day 90/20 VPD and PPDF were fine today with normal settings of 74F/55%RH/Auto ILV - PPFD ranged from 550 to 750 because of HST on the limbs. This will be the last stress I give her and hope it wasnt too much. Hoping this all results in a big yield and not a herm.

Can't believe these now absolutley smashing it. Think it's another week of Overdrive for a few of them and then flushing. There is one that developed some black spots which I think is potassium deficiency. Other than that the rest are doing amazing under the Spider Farmer and Advanced Nutrients. The Purple is crazy really don't wanna chop it down become attached haha Smells like blackcurrant fruit punch omg Unreal . One smells like giant bag of skittles fruity as hell man! 2 weeks maybe and she done 💪👽

Seedling managing 93F 30%RH, around 20 DLI. Vpd is in the 3's. No I don't recommend. Signum Magnum. "A great sign appeared in the sky a woman clothed with the sun with the moon under her feet and on her head a crown of twelve stars. Sing ye to the Lord a new canticle: because He has done wonderful things. Glory to the Father, and to the Son, and to the Holy Spirit As it was in the beginning, and now, and ever shall be, world without end." The plant nutrient nitrogen exists in forms with both positive and negative charges. Ammonium (NH4+)(immobile in soil)(Cation) has a positive charge, while nitrate (NO3-) (highly mobile in soil)(Anion)has a negative charge. Nitrogen is unique among plant nutrients in that it can exist in both positively charged (ammonium, NH₄⁺) and negatively charged (nitrate, NO₃⁻) forms in the soil. This makes it a special nutrient. In that it is responsible for providing balance for reactionary trade offs when it comes to ph. Because ph itself in the medium will always slowly drift towards acidicity, such is nature. 80% of nitrogen should be nitrate and no more than 20% ammoniacal nitrogen. Ca, mg, and K are the big 3 cations related to soil composition, pH & base saturation. When nitrogen is in the form of ammonium, it can compete with calcium, magnesium, and potassium for absorption sites in the plant root. This competition can lead to a reduction in the uptake of these other essential nutrients. Nitrogen, particularly in its nitrate form (NO3-), can increase soil acidity, which can also affect the availability of calcium, magnesium, and potassium. The form of nitrogen applied (ammonium vs. nitrate) can influence its interactions with other nutrients. Ammonium nitrogen can have a more pronounced negative effect on the uptake of calcium, magnesium, and potassium compared to nitrate nitrogen. Common forms of ammonium nitrogen include ammonium ion (NH4+), urea, and ammonium compounds like ammonium nitrate, ammonium sulfate, and ammonium phosphate. Common forms of nitrate nitrogen include potassium nitrate (KNO3), sodium nitrate (NaNO3), calcium nitrate (Ca(NO3)2), and ammonium nitrate (NH4NO3). Phosphorus is an essential plant nutrient, and its availability in the soil is strongly linked to the presence of oxygen. Plants primarily absorb phosphorus as phosphate (PO4), and oxygen is a key component of this molecule. Furthermore, the availability of phosphorus in the soil can be impacted by factors like soil aeration and temperature, which in turn affect the oxygen supply to the roots. Phosphorus uptake in plants is most critical during the early stages of growth, particularly within the first few weeks of plant development. Young plants actively growing tissues have a high demand for phosphorus. They may absorb up to 75% of their total phosphorus requirements within the first few weeks of vegetative growth, with up to 51% of uptake happening overnight, primarily in the first few hours or early nightfall. ⑨Anaerobic root respiration, or respiration without oxygen, is detrimental to plants because it's less efficient and produces toxic byproducts, leading to reduced energy production, nutrient uptake issues, and ultimately, root damage and plant stress. ⑨Anaerobic respiration, unlike aerobic respiration, doesn't utilize oxygen as the final electron acceptor in the electron transport chain. This results in a significant drop in the amount of energy (ATP) produced, which is necessary for various plant functions, including growth, nutrient uptake, and maintenance of cellular processes. ⑨In the absence of oxygen, plants produce byproducts like ethanol and lactic acid during anaerobic fermentation. These byproducts can be toxic to the roots and inhibit their function, ⑨When oxygen is depleted in a medium, the pH tends to decrease (become more acidic) due to the production of metabolic byproducts. This is particularly relevant in biological systems where aerobic respiration relies on oxygen as the final electron acceptor. ⑨When oxygen is scarce, plants may switch to anaerobic respiration. This process produces carbon dioxide (CO2) as a byproduct. ⑨CO2 dissolves in water to form carbonic acid (H2CO3). This acid lowers the pH of the medium, making it more acidic. ⑨Anaerobic conditions can impair a plant's ability to regulate its internal pH, leading to a drop in cytoplasmic pH and potentially cellular acidosis. ⑨The change in pH can also affect the availability of certain nutrients to the plant, as pH influences the solubility of micronutrients like iron, manganese, zinc, copper, and boron. ⑨The lack of oxygen in the plant medium leads to a decrease in pH due to the production of carbon dioxide during anaerobic respiration and impaired pH regulation within the plant. In plant cells, cellular acidosis, a drop in the internal pH of the cytosol, is a significant stress response, particularly during conditions like flooding or hypoxia. This acidification can be triggered by a decrease in oxygen levels, leading to the production of metabolic byproducts like lactic acid and CO2. The plant's ability to tolerate and recover from these conditions depends on its cellular mechanisms to regulate pH and mitigate the effects of acidosis. When plants are subjected to low oxygen environments, such as those experienced during flooding, anaerobic metabolism, which produces lactic acid and ethanol, becomes the primary source of energy. This can lead to a build-up of these acidic metabolites in the cytosol, causing a drop in pH. OXYGEN Atomic oxygen (single oxygen atom, O) is the lightest form of oxygen, as it has the lowest mass of the oxygen molecules. Oxygen also exists as a diatomic molecule (O2) and an allotrope called ozone (O3), which have higher masses due to the number of oxygen atoms combined. Atomic Oxygen (O): This refers to a single oxygen atom, which is the most fundamental form of oxygen. Molecular Oxygen (O2): This is the common form of oxygen we breathe, consisting of two oxygen atoms bonded together. Ozone (O3): This is an allotrope of oxygen, meaning it's a different form of the same element, consisting of three oxygen atoms bonded together. Since atomic oxygen has the fewest oxygen atoms, it naturally has the lowest mass compared to O2 or O3. Ozone (O3) Lifespan: Ozone has a relatively long lifespan in the stratosphere, particularly at lower altitudes. For example, at 32 km in the middle latitudes during spring, ozone has a lifetime of about 2 months. Oxygen (O) Lifespan: Atomic oxygen, on the other hand, has a much shorter lifespan. At the same altitude, its lifetime is about 4/100ths of a second. Ozone-Oxygen Cycle: The ozone-oxygen cycle involves the rapid exchange between atomic oxygen (O) and ozone (O3). UV radiation can split molecular oxygen (O2) into atomic oxygen (O), which then reacts with O2 to form ozone (O3). Ozone can also be photolyzed by UV radiation, creating atomic oxygen again, which can then react with O3 to reform O2. Dominant Form: The partitioning of odd oxygen (Ox) between ozone and atomic oxygen favors ozone in the lower stratosphere. This means that a much larger proportion of odd oxygen exists as ozone than as atomic oxygen, especially in the lower stratosphere. Recombination: Atomic oxygen has a high energy and reactivity. When it encounters another oxygen atom, they can combine to form O2. This process releases energy, contributing to the heating of the atmosphere. Ozone Formation: Atomic oxygen can also react with molecular oxygen (O2) to form ozone (O3). Ozone plays a significant role in absorbing harmful UV radiation. Other Reactions: Atomic oxygen can react with various other molecules in the atmosphere, like nitrogen (N2), water (H2O), and carbon dioxide (CO2), forming different compounds. UV light below 240nm (peak 185nm) creates ozone (O₃) through a process called photolysis, where UV light breaks down dioxygen molecules (O₂) into single atomic oxygen atoms (O). These single oxygen atoms then react with other oxygen molecules to form ozone (O₃). Specifically, UV-C light with wavelengths shorter than 240 nm can cause this photolysis. UV light with wavelengths between 240-280 nm, (peak 254 nm) breaks down ozone (O₃) into dioxygen molecules (O₂) and atomic oxygen atoms (O). 280nm does not have the energy potential to break apart the stable bond of (O₂) into enough (O) to make (O₃) At ground level, atomic oxygen (single oxygen atoms) has a very short lifespan. This is because it's highly reactive and quickly combines with other molecules to form stable diatomic oxygen (O2) or other compounds. While the exact timeframe varies depending on the specific circumstances, its lifespan is typically measured in nanoseconds or picoseconds.

Nuevo cultivo, volví a plantar Jamaican Dream, está vez solo se hará LST y defoliación, nada de apical(Main Lining). Se ha aprendido de errores y atrasos del cultivo anterior, esperando no cometerlos en este cultivo. Para este cultivo de usarán los nutrientes de la línea Grotek(mega pack), además de micorrizas great white. Las semillas germinaron al tercer día de plantadas en el sustrato, al igual que el cultivo anterior. Esperaré a que crezcan hasta unos 3 nodos para hacer transplante a maceteros definitivos de 18 litros. Germ2, han estirado suficiente para remover el plástico, se regaron con agua de osmosis con CalMag a 0.6 EC y pH 6.5, se espolvoreó great white en el sustrato. Se instalo un humidificador en el indoor y se bajó a un 70-80% la potencia del LED. Germ3, se mantienen en 80% de humedad a 23 grados, se humedece el sustrato. Germ6, están creciendo al ritmo esperado, se humedeció el sustrato, los parámetros están correctos. Germ8, primer riego con Vitamax Pro y SoloTek Grow de Grotek, 0.8 EC, y un poco de great white en polvo al sustrato. Creciendo bien.

Finales de la pasada semana y esta lavado de raices. Agua con ácido cítrico y ácido ascórbico. Corte de los apicales más formados y con mayor riesgo de botritys y el resto seguirá una semana 10 dias más. Han salido diferentes fenotipos, unos de más skunk y otros de más Critical, A los 60 dias obté por cortar los apicales y dejar el resto de las plantas para que terminaran de engordar y madurar. Entonces volví a regar con Bloom Bud y call-Mag -

Растениям от IZI осталось дней 7. Анубису дней 10-14, CloudWalker'у от двух недель, максимум 3, фенотип сативный + поздний зацвет (почти на неделю позже) Как тут внести новые удобрения? Добавить его в базу. Хоп-хей спамеры, кто зарабатывает хуй знает сколько в час? Общий вид не возможен - сломалась камера, только макро.

GENERAL COMMENT. So the RQS STRESS KILLER AUTO is down. Now we have the NL to manoeuvre and try to keep her alive for the final flush. RQS NORTHERN LIGHTS AUTO COMMENT. Many but slim colas emerged, showing extreme spotting and deficiencies, but gained weight since last week and started turning purple, first time that happens. So now the final flush started and hope, afraid taste could be off, because of the problems i ran in with her, probably a good strain to considere light feeding, the smell is very gentle, a good strain to do stealth. 10-14 day to go! Yield could be amazing but will be common because of the locks, nothing out of the curve in my opinion, something to retry and correct to deal with this strain. Not turned on or off by her just feeling neutral and glad she made it. Trichomes wise she is just ready, mostly cloudy, she will finish with some amber will do a nice sleeping aid. Trim job will be a pain on this one because i will clean all the small affected spotted leaves.

Day 29. Heavy work in progress, update will follow... Day 30. Job done, most lost almost all big fan leaves, all 3 Kushes where toped. In plans one more heavy training session in a week time, few days to recover and hopefully flower !!! Skunks overgrew Cheeses and start to smell, really to STINK ;)) And i love it !!! Next watering - full feed. Day 31. All Kushes have mini mag deficiency, but i get it with my lights often and know how to fight in early stages. All girls will get 3 feeds in a row. 1. CalMag only 2. Silica acid only 3. Full range of Biobizz feed. After installing new air fans, have to water girls almost every day. Try to feed them only once a week, but pot space taken in full by most of the girls and its time for first mini boost. Day 34. Girls got really heavy defoliation, HST , toping and LST session. First time in my life i trim toped plants so much, but they where reaching sky and stems too fragile for supercroping yet, i do it on branches, but not on mains. So i guess they will slow down a bit ;))) All girls got silica acid after. Happy Growing !

This has been a fun week for this Cheese from Humboldt, it has made a mini flower on one of its fan leaves and a bee got wrecked in one of its flowers. I want to say it got stoned, but no idea if they can, the bee was super chill I could pet it and get real close with the macro lens, it did not care one bit. It could have been injured from something else like a predator or pesticide but she was gone by the following evening. Other then that nothing to new, the plant is growing nicely and I have no complaints about it. I keep comparing the smell from it to the other cheese variety from Dinafem I'm growing and they are different but I cant yet focus in on how, will be better adept at doing this once they are both in flower, I got high hopes for both plants. Added in the standard 2 week fertilizer Acti-Sol Tomato & Vegetable 4-6-8, had it fortified into the soil from the get go so did not add extra it in till now. About one month out.
