I don’t know where I really went wrong, pretty sure it’s some type of nutrient burn. 100% organic nutrients a 645 blend OmRI listed. I’m using the same organic blend on all of my trees and this is the only one that looks like that, using the HLG 550s temperatures have stayed under 80° and above 70 with more than sufficient airflow!

Thank you. Gave her a cocktail to help with stress. Added 1st net for lateral support, not so much now, but for later. Blue light is absorbed by photoreceptor proteins called phototropins, which trigger a hormonal response that causes cells on the shaded side to elongate, making the plant bend toward the light. Try and fill this side a little. She is quite big already, just needs to find her stride again after the undue torture. 5 apex stems with 20-30 mini cola, let them develop a little, with the apical dominance shattered, all those 20-30 will all compete with each other as soon as that stretch is initiated. Key to a good stretch is making sure the plant is cycling efficiently, with large ATP conversions occurring lights out. For now, I'm keeping light intensity high. A plant will slow its vertical growth in very high light intensities, leading to a more compact form with thicker stems and leaves. This response is a protective mechanism against light stress, which can damage the photosynthetic apparatus and lead to symptoms like leaf scorching, yellowing, and brittleness. Instead of growing taller, the plant invests its energy into creating a more robust, stress-tolerant structure. Providing plants with necessary antioxidants helps protect the photosynthetic apparatus by scavenging reactive oxygen species (ROS) that cause damage from excess light. UV light exposure can impact the xanthophyll cycle by either enhancing its photoprotective role or causing damage, depending on the intensity and type of UV radiation. UV exposure can trigger the synthesis of more xanthophyll cycle pigments to increase the plant's capacity to dissipate excess energy, but it can also cause direct damage, particularly to Photosystem II, and may lead to a decrease in the de-epoxidation state (DEPS ratio) which indicates a reduced capacity to dissipate excess energy. Plants can respond to UV stress by increasing the synthesis of xanthophyll cycle pigments, such as violaxanthin and zeaxanthin, to improve their photoprotective capacity. UV-induced changes in xanthophyll cycle pigments can be linked to a plant's overall tolerance to high radiation stress. The xanthophyll cycle helps protect against photoinhibition, which is especially important when the plant is exposed to high levels of both UV and visible light. High doses of UV radiation can directly damage photosynthetic components, including the proteins, lipids, and pigments in the thylakoid membranes. Exposure to UV radiation can have a mixed effect on the de-epoxidation state (DEPS ratio) of the xanthophyll cycle pigments. In some cases, UV can inhibit the conversion of violaxanthin to zeaxanthin, resulting in a lower DEPS ratio and a reduced capacity for energy dissipation. However, the total pool of xanthophyll cycle pigments may increase, and this enhanced pool size could provide a greater potential for photoprotection despite a lower DEPS ratio. The xanthophyll cycle works alongside other mechanisms, such as the accumulation of flavonoids (UV screens), to protect the plant from UV-induced damage. Blue light repairs 100% UV-induced damage in plants through a process called photoreactivation, which uses a light-dependent enzyme called photolyase. This enzyme uses energy from blue and UV-A light to directly reverse the damaging pyrimidine dimers in the DNA caused by UV-B radiation, a key mechanism for maintaining the plant's genetic integrity. After carbon, light, water, temperature, and nutrients, the limiting factor of a plant's growth is often its own internal factors or the amount of a key ingredient. Chlorophyll concentration is one such factor, as the amount of this pigment limits how much light can be captured for photosynthesis. Other factors include chloroplast number, respiration rate, and the concentration of carbon dioxide in the atmosphere, as plants are often in a CO2-deficient condition. 60x60x18=64800seconds x 700 = 45,360,000moles. 45DLI Exposure to 165 µW/cm² of ultraviolet-B (UV-B) light for 3600 seconds = 1 hour, a extremely high, acute dose triggering stress responses and protective mechanisms. . The plant's photoreceptor protein, UVR8, senses the UV-B radiation. This triggers a signaling cascade that activates specific genes to protect the plant from damage. In response to the UV-B signal, the plant ramps up the biosynthesis of protective compounds like flavonoids, phenolic acids, and anthocyanins. These compounds absorb UV radiation and accumulate in the epidermal layers of leaves to shield inner photosynthetic tissues. The plant may increase leaf thickness or deposit more cuticular wax, creating a physical barrier to the radiation. The plant will produce more enzymatic and non-enzymatic antioxidants to neutralize the reactive oxygen species (ROS) produced by the UV-B radiation. The plant activates enzymes, including photolyases, to repair DNA damage caused by the UV-B. These repair mechanisms are critical for preventing permanent genetic mutations. While protective measures are activated, a high dose delivered over a short period can cause stress that overwhelms the plant's defenses. Photosynthesis is highly sensitive to UV-B. A high dose can inactivate Photosystem II (PSII), damage thylakoid membranes within the chloroplasts, and reduce chlorophyll content, which lowers the plant's overall photosynthetic capacity. Despite repair mechanisms, high UV-B doses can inflict persistent damage on the plant's DNA. The overproduction of reactive oxygen species can cause oxidative stress, leading to the oxidation of lipids and proteins and disrupting cellular function.

They are all doing great. I cleaned my resivor and forgot to turn the valve back on. In less than 24 hrs my boy starts wilting ( he is such a pussy ). Other than that things are good. My light decided it was tired and wanted to quit working. It is 3 years old, but I barely used it. I have a spare, but anyway its time to shut it off. They are getting about 14 and 1/2 hours of sunlight. The longest day of the year was on Friday. Its almost like it knew. 😂🤣😂🤣 They should already be outside in the final pot..... but I'm behind. They should be 5 feet +.... but I'm behind. My boy is the tallest at 43 inches and the shortest girl is 36 inches. I will transplant into 25 gallon hard plastic pots. This grow will be slightly different this year. Somehow I will make it happen. I'm thinking of cramming them into tomato cages, and seeing what happens. I'm not even sure if I'm going to top them. I am just going to play it out and decide later, or not decide. I'm sure it will have some ups and downs.

During week 12 the plants are in their 5th week of flowering since the switch to 12/12 hours of light/darkness. All plants develop nice flower crowns now and the top-buds start to get encrusted with trichomes. Especially the MAC from Tropical Trees seeds from Hawaii has already an impressive layer of trichomes on top. All 12 plants have a nice healthy green color, which shows the BIO NOVA nutrients work GREAT! 💪😎 My two SANlight EVO4-120 LEDs are doing an EXCELLENT job and are running on 100% power now (=3 GREEN lights on the dimmer ON). This cycle is going AWESOME until now and I cant wait for the buds to get bigger...

We are really a very short time from the harvest, 5 days compared to the six weeks declared and actually we are. The trichoms and red hair are taking color the plant is mature or still lacks little. The flowers are beautiful, the topping at 16 pounds worked great. There is a scent of paradise, of Pussy of beautiful Ninfa Devvero. LIGHT >> MARSHYDRO SP3000 AT 100% OF POWER, we already like it so much because it covers the intact length of the tent.

- Ich hab die erste Woche des Biobizz Allmix Düngeschemas gestartet und gebe wie immer erstmal vorsichtige 100%, da meine Erde an sich durch den Kompost recht potent sein sollte. - Außerdem hab ich mit meinem Calmag-Rechner mein Leitungswasser angepasst. Die Werte könnt ihr auf den Bildern sehen. - Den PH-Wert passe ich ebenfalls auf 6,5 an.# - Die Lampe bringt zur Zeit etwa einen PPFD-Wert von 350 - 360 µmol/s/m² bei 18 Stunden Beleuchtungszeit (DLI von 22 - 23 mol/d/m²). Sie wird aber nur eingesetzt bis es warm genug draußen bleibt. Tagsüber stehen sie jetzt schon draußen, sofern es nicht regnet oder stürmt. Die Tropicana Cookies macht sich hervorragend und sie ist sehr uniform mit den anderen Fastbuds Strains bis jetzt. Sieht gut aus finde ich 💪😁👍 YT: www.youtube.com/@High-And-Hydro

What a great week it has been! Starting to see my nugs ripen up 😎 every time I shine a light on the buds all I see is a bunch of crystals! It’s looking beautiful. There are some plants that are growing fatter nugs than others. the blue dream and the fresh air as well as the white runtz seem to be doing particularly well, I started feeding mother of all bombs as well as overdrive this week I may have overdone it on my first feed since I did notice some burn on the leaves I will go lighter on my next feeding for sure. i’m hoping to harvest the 22nd of this month and that will put me at 9 weeks of flowering. i’ll wait 10 week if need be though.

11/19 Week 8 Still building, no signs of slowing down though leaves are fading. 11/20 Can anyone say rainbow sherbet? Absolutely candy here 11/22 Fed Bio-Bloom 7 ml / CaliMagic 4ml / Recharge 0.5 tsp per gallon PH 6.5 We had a oops and the room overheated for about an hour or so and may be some foxtailing due to that. Nothing for it now

Week 12 During this week I will continue to flush the plant only with water. I guess that this could be the last week, let's see what trichomes will say! D79: added 5 liters of tap water to continue the flush. The plants has stunning colourful buds! D81: added 5 liters of water. Trichomes check: there is a quite good balance between amber and milky; two days to the harvest. D83: end of the journey!

Zdravim všechny po dalším týdnu✋ dneškem 18.5. startuju 2. týden květu. Major vypadá velmi spokojeně, pomalinku se začíná roztahovat po celým stanu i se docela vytáhl, zatím na něj kromě překládání listů nešahám a vypadá, že mu to tak vyhovuje😉 Dělá mi radost, začal hezky bumbat. 5L zálivku si říká každý 2 dny. A+B jsem zvýšil na 2ml/L Vyřadil jsem Voodoo, Tarantulu jsem ještě nechal, ale ta už půjde taky koncem tohodle týdne pryč. Teplota pořád stejná 24-25°C. Vlhkost se motám kolem 55-60%. Ph. si plave 5.7😎 Všechny fota jsou z 18.5. Ať se vám daří a za týden zdar👋

Vamos familia, actualizo la novena semana de floración de estas Royal Gorilla de RoyalQueenSeeds. Se estropean un poco por el calor aunque se les ve sanas, están formándose las flores bastante bien. Y desprenden ya un aroma increíble. Hasta aquí todo bien el único suplicio que sufro son altas temperaturas por estar en pleno verano. Acabaré este proyecto y daremos parón unas semanas. Que avance algo más el verano. Máximas de 30 y mínimas de 27 ahora viene el calor y ando jodido en humedad ronda el 40%. Hasta aquí nada nuevo no sé si las dejaré más o que haré podría cortarlas ya o darles 5 - 7 días más, todavía no e decidido. Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Mars hydro: Code discount: EL420 https://www.mars-hydro.com/ Hasta aquí es todo , espero que lo disfrutéis, buenos humos 💨💨
