First week of flower is in the books. I posted my feeding schedule in the pics above. If you find yourself looking at it wondering why you're seeing back to back feeds with mycos or teas its because with organics you never want to let your pots dry out. You obviously dont want to waterlog the pots but you need to find that balance with watering so as to keep your ecosystem happy and active. It's not a feed/water/water system where you're watering every other day as you do with salt based bottled nutrients. Always remember you're feeding the microboes/fungi/bactria and they are feeding your plants. If you dry your pots out with organics those elements become dormant and or die off which will lead to deficiencies and a weakened immune system. The week was going smoothly until last night. The timer for whatever reason didnt kill the lights after 12 hrs had past so they got a little over an hr of extra light. To help maintain consistency with the plants I just altered on/off times to make sure they still recieved 12 hrs of darkness. So I was running 6pm-6am now with the overage last night I'm running 730pm-730am. I have heard some horror stories about how something like this has affected people's plants but they are few and far between. I'm not overly worried about it as a plant thats growing outdoors never gets a true 12/12 lighting period. I caught it early, adjusted my lighting schedule to accommodate a 12 hr off period, and being so early in the flowering stage I should be ok. Obviously it goes without saying but this is taboo and not something you want to be making a habit of with photoperiod plants. My dehumidifier also decided to do it's own thing last night and didn't shut off as per the settings (set to 45%) and as a result it pulled my humidty down to 39% down from the 45%-47% that the room usually runs at. As a result my temps rose into the 28-29 Celsius range overnight up from the 25-26 Celcius (my preferred flowering temps) that the room usually sees. So she was quite the party downstairs while I was sleeping. To my surprise when I turned the lights on the plants looked very happy and healthy and immediately started praying to the sun gods. I got lucky here with respect to what I was speaking about above with watering practices and organics. As I keep my pots in the sweet spot with daily waterings this didnt negatively affect the plants. I've prepped and am bubbling a compost tea (posted a video) which will be fed tomorrow. I also through some organic popcorn seeds and organic mung bean seeds in the seed sprouter (pic posted above) to make a popcorn/mung bean SST for the plants that's loaded with all kinds of enzymes and goodness. It's also pretty sweet to be able to say you feed your plants popcorn. Like I mean really though 😁. I'll talk a little more about SSTs next week but if your curious about it there are many websites about this topic, homesteadandchill.com would be a great place to start. They lightly touch on topic without diving to deep into the science behind it so it's easy reading to help introduce you.

Ok start of week 5. Done a big defoliation on all 4 plants. Last weeks topping and fiming seems to have gone well the plant didn’t react bad to it at all. The fiming seems to of given me at least 4 new main trunks per plant and the topping 2. Going to make this the last week for veg then next week flick them over to 12/12. Happy growing all 🍻

I loved growing this plant. I have learnt so many new things. This is the first time I topped, defoliated, attempted to mainline, and everything seems to have worked out pretty well. I have made some mistakes here and there, but that's part of the learning process and lead to a pretty interesting grow :).

Notes to follow shortly, just trying to get all the pictures up and organized !!! So on this week , the buds are fully recovered, just about ready to be chopped down ! There are some brown tips and discoloration in the leaves but that was all on purpose . I overly increased the air movement, as a result some of the leaves got some wind burn . Not an issue it will just add to the magic of the smoke . ***************************************** My White Powdery Mold solution: 1) spray Diablo nutrients Monster Wash. 2) Add a certified HEPA filter to your grow area. 3) Increase airflow, even if the plant is getting alot of wind , at this point, the positive greatly outweighs the negative. 4) PRAY 🙏 lol even if your not religious! 5) Cut off all nutrients, do this just in case you do have to do a cut down quickly that at least at the very least what is good will be white burning and flush properly. 6) Raise the PH of your soil ( via water that is above 7.0ph) I believe I got very lucky on this one just due to my ability to recognize and diagnose problems. I was not done alone it was done with the advice of mentors the years of listening the amazing nutrients I use. Last but very not least the incredible genetics of exotic seeds. Without: Diablo nutrients + Exotic seeds I would have been in a way worse situation. If you ever struggle with white powdery mold or if you need someone who has some experience in this feel free to hit me up via message anytime.

Buenas a todo compañer@s,otra semana más de cultivo. Amnesia haze Hoy día 3 Finalizamos la semana 5 de floración. Cambiamos a la semana 6 Aumento de la EC hasta los máximos valores que acepte la variedad,proabado este fenotipo de amnesia haze en varios cultivos con una EC2600 en sustratos. Una semana bastante jodida de agua,muchas lluvias,con lo que conlleva alta humedad en el exterior y con ello más alta en el cultivo. Pero seguimos luchando! Dia 5 Todo bien ,exceptuando una de las niñas que parece tener alguna deficiencia,magnesio pensé en primera estancia,pero otros compañeros me dijeron que podría ser que el magnesio bloqueó el potasio en unos riegos atrás. Le reduciré el magnesio,y le seguiré dando la misma dosis de potasio que le doy a todas las demás.. El riego es por goteo y no queda otra, a esa pequeña le añado lo que pida de más con una pequeña pistola de agua por debajo. Va afinando el cultivo con respecto a los olores.

This was a big girl to harvest. She came in at 417.3 g dry, which is a personal best for me. Additionally, I received 36g of nice trim for my tincture. The buds aren't the biggest I have grown, but they are some of the tightest! I really enjoyed growing this clone. She filled out the tent well using a type of SCROG to get the most out of the grow area. I dried the buds on a drying rack for 10 days, and then gave them a nice rough trim. Since this is all for personal use, I don't worry about making them pretty, just functional. She is a sticky girl, and gummed up my scissors more than once. That is a good problem to have! I put the trimmed buds in my Grove 1/2 gal bags for the cure. I have found these bags to be EXCELLENT to cure my buds. No burping is required, they preserve the terps, and keep the humidity between 58 and 62. Perfect! My best harvest to date!

Seedling popped above ground 05-05-2020. It is a bit difficult tracking temperatures and humidity since shes growing basically outside. Humidity ranges from like 20%-90% throughout the day/night. Temperatures differ every day depending on the weather as this small plastic greenhouse does not really contain any heat. The timelapse is not optimal at this moment as the camera's time was off by 2 hours and starts/stops timelapses based on sun up-down. Timelapse uploaded, more pics on their way.

Wish the buds would have got a little bigger but feel like that’s particularly my fault for a short Veg but overall I am blow away by the outcome for all the seeds to just be random bag seeds! 2 of the plants are drying now 3rd one will be cut tomorrow & the other 2 got probably 2 more weeks! Will do a taste & smoke report and also give a weight as soon as they dry & cure a little bit but honestly couldn’t be happier with my first grow! Thanks for all the support & help along the way & happy growing friends!🤙🏼✌️🏼🌱 Update on 1st plant - dry weight 42g, still smelled pretty Earthy when I put it in the jar but the smell is definitely coming out now, extremely sticky & frosty buds❄️: 1:🏼🙏🏼 Update - plant 2 Dry weight was 40 grams! Extremely happy with the out come this is honestly some of the best bud I have ever smoked! Amazing to me this came from a random bag seed, it has a very citrusy flavor, smells & smokes amazing! Honestly a 10/10 in my book, wish I could knew what strain this was so I could grow it again!😫❄️✌️🏼🌱 Update - plant 3 Dry weight 34g, smells & look phenomenal, the buds are much smaller & had the smallest yield so far but this is by far the best smelling so far! Will have a smoke update on this one soon, stay tuned friends & happy growing!✌️🏼🌱 Update - plant 5 dry weight was 52g it dried a little faster than plant 4 which I will probably jar tomorrow! Will update again with a smoke report soon, this plant brought my total so far up to 168 off 4 plants👍🏼 Thanks for following friends & happy growing! Also the butter I made from the trim was 🔥🔥

Querido diario, esta semana he crecido 3cm por arriba y tres por abajo... me estoy haciendo mayor!! 07/01/21 Hoy he pasado todo el día mirando por la ventana, es todo luz y color!! 😘 Mi armario es triste, aunque al menos se está caliente y me da luz cuando el día acaba, he estado haciendo señas a las otras plantas a través del cristal, pero ellas no se mueven, no responden, parece que les cuesta, tienen las hojas muy gordas, no como yo, que soy liviana, elástica y grácil... me quiero!! 😍 11/01/21 Ya he desarrollado mi tercer nudo, mi cultivador está muy contento, pero sobre todo porque me ha dicho que mis raíces están creciendo perfectas; blancas, peludas, vigorosas y muy verticales... me ha dicho que si sigo así la semana que viene me trasplanta a una maceta mayor, que será mi suelo para toda la vida!! 😊 Le he preguntado que maceta me pondrá, pero me ha dicho que no lo sabe aún, pero que me reserva algo especial!! Yupyyy!! Me ha dicho también que si me porto bien y sigo creciendo me va a poner un armario de floración para mi sola!!.... que suerte!! 😋 Anoche mi jefe me preguntó si no tenía sed, porque dice que consumo mucha agua, le he tenido que explicar que la temperatura de estos días y mi tamaño no necesita más, que por ahora mis raíces crecen libres por los agujeros de la maceta y captan la humedad ambiente. Aun así anoche mi cultivador me regó con un agua templada que me sentó muy bien, además desde ese riego siento unas cosquillas en mis raíces, mi jefe dice que son los Microorganismos que me inoculó y que serán mis eternos ayudantes para el flujo de nutrientes y minerales por todo mi ser. Esta mañana los he conocido!! 😳 son muy, muy pequeños, no los veo, sólo los siento y los escucho 😦, me han dicho que ellos necesitan constantemente la energía que produzco, captada de la luz... el azúcar, porque los MM son diabéticos y no almacenan azucar, si tienen ellos trabajarán día y noche para solubilizar los nutrientes del suelo y pasármelos a mi... no estoy segura de poder hacerlo... soy muy pequeña 😨... le voy a a preguntar al jefe... Ya lo tengo claro!! 😊 vengo de hablar con el jefe y me ha dicho que no me preocupe por el azúcar, el le dará melaza a los MM y también la materia orgánica para que coman y se reproduzcan por millones y mantengan mis raíces muy funcionales para absorber todos los nutrientes que necesito... Yeah, que haría yo sin mi jefe?!! 😁 Hoy estábamos todos contentos, bueno menos el perro de mi jefe, que me ignora y sólo quiere comer y jugar... es un presumido!! Hoy para festejar el día nos hemos hecho un selfie, mi jefe, mi prima Sweet Amnesia Haze y yo... estoy haciendo migas con mi prima, aunque es muy pequeñita todavía y habla poco, yo la cuido como si fuera su hermana mayor, dormimos hasta en la misma cama. Realmente los días de esta semana son muy tranquilos y hasta monótonos, mi jefe se esfuerza en mantenernos calentitas, pues el frío exterior es mucho... pero hoy la rutina se ha roto!! una vibración muy agradable y estimulante ha recorrido todo mi cuerpo... he conocido la música!! 😁... estoy tan emocionada que mi cultivador me ha preparado un escenario, y ha dicho... que no pare la fiesta!! y también me ha dado una mariquita para decorar mi pequeña maceta... mi primera joya!! 😁 En esta discoteca improvisada hemos bailado, cantado y hecho coros, para acabar regados con la emoción incontenida de dos amigos inseparables!! - And when I'm lonely, Cherry's there --And she plays along while I sing out my blues... - Maybe we could talk 'bout things - If you was made of wood and strings... - Her name is AKU, we've just met.... ... estoy Happy, amo mi vida de plántula!!

🌸 White Widow — Week 7 Flower (Week 11 from seed) Status: Full flower, bulking rapidly. Vibe: Dark foliage, compact form, heavy frost, 90s aroma profile. Feeding: Aptus + Plagron lineup (Power Buds, Sugar Royal, Green Sensation, Regulator, CalMag, All-in-One) Photos: Sony a6000 — loyal workhorse for studio shots. 📷 ⸻ 🧠 Deep dive — Why 12/12-from-seed makes a plant “go hard” Plants evolved to reproduce. Their primary biological drive is to make seeds. Photoperiod (day length) is one of the most reliable seasonal cues plants use to decide: is it time to flower? Mechanisms at play (simple → nerdy): • Photoperiod sensing: Leaves detect day length via phytochrome systems (Pr Pfr). Short days (or the 11/13 rhythm) flip the hormonal cascade toward flowering. • Florigen & flowering hormones: When the plant senses “short days,” it produces mobile signals (florigen) that travel to the shoot apex and shift gene expression from vegetative growth to reproductive development. • Carbohydrate reallocation: Energy stops making more leaves/branches and is directed into calyxes, resin synthesis, terpene pathways, and seed/flower tissues. • Result: A plant that thinks “the season’s ending — reproduce now!” goes all-in: denser flowers, rapid calyx swelling, intense trichome production. Important point: they don’t know about pollination. The plant can’t tell you whether pollinators exist or whether pollen will land — it simply invests in attractive, resinous flowers to maximize reproductive success. As growers, we exploit that drive to produce potent sensimilla (unpollinated) flowers. ⸻ 🔬 Why your White Widow is exploding in quality right now • Immediate reproductive programming: Starting floral signals early (12/12 from seed) forces the plant to prioritize flower formation rather than vegetative mass. That yields compact, dense colas. • High PPFD + short day = strong DLI in less time: With fewer hours of light, your lamp intensity is higher in those hours → powerful photosynthesis during the window the plant has chosen. • Nutrition tuned to flower: the Aptus + Plagron stack feeds the metabolic surge — PK + biostimulators for bulking, sugar stimulators for terpene pathways, Ca/Mg for structural health. • Genetics: White Widow is resin-happy; give it the right cues and it will frost up like a sugar cookie. ⸻ 🌈 Why her colors are going dark (and why that’s beautiful) Leaf & bud color comes from a balance of chlorophyll + accessory pigments (anthocyanins, carotenoids) and is influenced by: • Genetic propensity (some phenos are naturally darker) • Temperature swings (cooler nights often increase anthocyanin expression) • pH / nutrient balance (some deficits/ratios nudge color pathways) • Light spectrum intensity (strong red/far-red influence can shift pigment expression) Dark phenos often correlate with high terpene and anthocyanin expression — visually stunning and often highly aromatic. ⸻ 🔁 Quick timeline recap (for newcomers) • Germination & early mistakes: initial heat-mat loss → restarted, one strong survivor. • Veg: compact, short internodes under the 11/13/12-12 shuttle → stacked nodes. • Early flower: slow to show, but once she flipped she committed. • Now – Week 7 flower (Week 11 from seed): heavy bulking, thick trichomes, deepening color, classic White Widow aroma emerging. ⸻ 🔭 What to expect next (this week → next week) Expect: • Continued bulking of calyxes and cola weight. • Explosion of trichome coverage — white, cloudy glands multiply. • Stronger terpene smell (earthy, spicy, resinous 90s profile). • Possible color intensification — deeper greens, potential purples depending on phenotype & nights. Do not expect: • Major new stretch — she’s committed to flower and will remain compact. • Immediate harvest — typical White Widow still wants its weeks; plan for patience (mid-late flower bulking happens over several more weeks). ⸻ ⚖️ Should you run all seeds 12/12 next cycle? (pros & cons) You asked if you might run every seed 12/12 — here’s the honest rabbit-hole: Pros • Much faster cycle → less time to harvest. • Compact plants → ideal for small spaces or stealth grows. • Often denser single-plant yields; less training needed. • Great for experimentation, multi-strain rapid rotation. Cons • Generally lower total biomass per plant vs. long veg runs. • Some genetics need veg time to express full canopy & branching; yields may be lower for those strains. • Root systems can remain smaller → may stress under high PPFD if not supported. • Less flexible for heavy-topping/lst/manipulation strategies. Bottom line: for strains with good genetics for flowers (like White Widow), 12/12-from-seed can be very rewarding. For sativa-dominant, tall strains you might lose yield without long veg. ⸻ 📷 Gear love — Sony a6000 shoutout I’ve got to echo it: that camera is a workhorse for growers. Compact, responsive, great color fidelity, and perfect for low-light studio shots when paired with proper exposure. The a6000 captures the leaf texture, color depth, and bud gloss in a way phones struggle to match. Long live the loyal shooter. 📸✨ ⸻ 🙏 Gratitude — the usual and the real Thank you to: • Zamnesia — for the genetics & the nostalgia. • Aptus & Plagron — the chemical & biological push that lets the plant sing. • ThinkGrow / Future of Grow / TrolMaster — lighting, control, and environment orchestration. • You — the makers, lovers, critics, curious readers — your energy fuels this diary. And to our White Widow — for showing up, forgiving mistakes, and giving back in beauty. 💚 ⸻ Week 7 flower — Week 11 from seed. Darker colors, heavy frost, the classic 90s scent, and a compact structure that proves 12/12-from-seed can produce absolute fire. We went full-in on Aptus + Plagron, kept the Emerson red-lead sunrise/sunset, and trusted the genetics. Watching her build is pure joy.

Be a giver, and the universe will give back in ways you could never imagine. 💚 Growers love to all P.S. — Deep dive on DLI (Daily Light Integral) — short, clear, and a little nerdy (in the best way). 🌞🌿 1) What is DLI, simply? DLI = the total amount of photosynthetic light (photons) a plant receives over one day. It’s expressed in moles of photons per square metre per day (mol·m⁻²·day⁻¹). While PPFD (μmol·m⁻²·s⁻¹) tells you instantaneous light intensity, DLI tells you how much light the plant actually used that day. ⸻ 2) The formula (how to calculate it) Use this exact formula: text{DLI (mol·m}^{-2}text{·day}^{-1}) = frac{text{PPFD (μmol·m}^{-2}text{·s}^{-1}) times text{seconds of light per day}}{1{,}000{,}000} Where seconds of light per day = hours of light × 3600. I’ll show worked examples so it’s easy to follow. ⸻ 3) Worked examples (digit-by-digit so it’s crystal clear) Example A — your reported PPFD ≈ 766 μmol·m⁻²·s⁻¹ and 11 hours light • seconds of light = 11 × 3600 = 39,600 s • photons per day = 766 × 39,600 = 30,333,600 μmol·m⁻²·day⁻¹ • convert to moles: 30,333,600 ÷ 1,000,000 = 30.3336 mol·m⁻²·day⁻¹ So: 766 μmol·m⁻²·s⁻¹ × 11 h → DLI ≈ 30.3 mol·m⁻²·day⁻¹ Example B — same PPFD but 12 hours • seconds = 12 × 3600 = 43,200 • photons = 766 × 43,200 = 33,091,200 • DLI = 33,091,200 ÷ 1,000,000 = 33.0912 mol·m⁻²·day⁻¹ Example C — other quick refs • 700 μmol × 11 h → DLI ≈ 27.72 • 800 μmol × 11 h → DLI ≈ 31.68 • 400 μmol × 11 h → DLI ≈ 15.84 • 1000 μmol × 12 h → DLI ≈ 43.2 (You can plug any PPFD and hours into the formula — those are ready-made reference points.) ⸻ 4) What DLI targets are useful for cannabis? • Vegetative (gentle): ~12–25 mol·m⁻²·day⁻¹ • Flower (typical good range): ~25–40 mol·m⁻²·day⁻¹ — most home/pro growers aim here • High-intensity/CO₂-enriched commercial: 40–60+ mol·m⁻²·day⁻¹ (needs CO₂, stronger conditioning) So your example (≈30 mol·m⁻²·day⁻¹ at ~766 PPFD × 11h) sits very nicely in the flower range. That explains the dense bulking + heavy resin you’re seeing — our DLI is right where White Widow loves to convert energy into flowers. ⸻ 5) Practical implications — what DLI affects and what to watch • Higher DLI → higher photosynthesis → more carbohydrate to drive bud bulking and terpene/trichome production. • Higher DLI requires more water and nutrients. Plants transpire more and pull more minerals; be ready to feed and irrigate appropriately. • Leaf temperature / heat stress: pushing PPFD up increases canopy energy/heat — keep airflow, VPD, and room temps under control. • CO₂ matters: if aiming beyond ~40 mol/day, elevated CO₂ (e.g., 800–1200 ppm) becomes productive; otherwise additional light won’t be used efficiently. • Distribution matters: DLI is an average over the canopy. Hotspots or shaded pockets mean some flowers get too much or too little — even light spread (and PAR mapping) matters. ⸻ 6) Actionable tips for your run (based on your 11/13 / 12/12 experiment) • We’re hitting excellent flower DLI (≈30 mol/day at 766 μmol × 11 h). That’s why buds are dense/frosty — keep the rhythm. • If you shorten hours (e.g., 11 h) keep PPFD high to maintain target DLI. If you lengthen hours (12 h) you can reduce peak PPFD slightly and still hit the same DLI. • If you raise PPFD to chase more DLI, ramp slowly (a few μmol/sec per day) to let stomata and roots acclimate — avoid sudden bleaching. • Watch watering & EC — higher DLI → faster uptake → more frequent but measured feeding. • If you ever push DLI 40 mol/day consider CO₂ enrichment and perfect VPD control to have that extra light used efficiently. ⸻ 7) Quick rules of thumb • Want to hit ~30 mol/day with 11 hours on the clock → aim for roughly 700–800 μmol·m⁻²·s⁻¹. • Want ~33 mol/day at 12 hours → ~766 μmol·m⁻²·s⁻¹ matches that nicely. • If you see leaf cupping/bleaching, you’ve likely exceeded safe PPFD for that canopy or temps are too high — back off, check VPD.

All going really strong. Auto Mazar measures at 2cm Auto Daiquiri Lime is 3cm and Auto Ultimate is 4cm. Gave them all 100ml of water mixed with Orca yesterday and nothing needed today!!!
