On day 13 they recieved higher nutriens EC 1 PH 6.4 Topped 4 plants on day 17 On day 17 I gave them another too hot nutrients solution EC 1.8 PH 6.5 can see some problems (in my opinion its nuts burn due not me realizing that soil was already a bit pre-fertilized + pushing everything too far due to its my first grow I found out at day 17, when I saw first signs - sadly I topped them that day and I brought them a lot more stress 😒 Transplanted plants into final 15l pots on day 20 Right now they are getting RO water only, will feed on day 22 again with EC of 0,9 I will aim for 6.2 PH as well EDIT: couple of people confirmed nutrients burn, so since I transfered 1l pots into 15l fresh lighmix, I will not feed until day 26 - they will get only hydro roots with RO water EDIT2: Forgot to write info about my light schedule - running lights at 240W and right now I am hitting around 375 PPFD with 18hrs on - so that is around 24.3 DLI :) I am checking it with LUX meter and converting to PPFD - then DLI

All in all I am quite happy with how things turned out. I got to use the short days to grow a photoperiod. This was not planed though, since it was packaged as a Skunk Auto. Unfortunately I again lost some (including the main bud) to mold. I think its Lemon Orange. Saw it grow before and it really looks the same. Smell is also in the neighbourhood ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Set up cost (fixed costs) -Lamp: 40€ -Timer: 3,5€ -Pot: 4€ -Total fixed costs: 47,5€ Given 5 years (or 15 grows) usage time translates to around 3,17€ per grow in materials. Variable costs: -Seed: 5,54€ -Soil: 4,5€ -Fertilizer: 3,50€ -Power: 26,90€ -Total variable costs: 40,44€ -Total costs per grow: 43,61€

From sprout, I've been watering every 3-4 days. Been very consistent with this. Yellow tips been appearing. I think it could be Magnesium or Calcium deficiency. Hit it with some Calmag with iron.

Esta por empezar el engorde final. Ya las flores estan casi formadas. La altura está al límite total. Uno o dos centímetros más y estaría en problemas de verdad. El engorde de muchas flores ya es notorio, pero creo que el uso de un bioestimulante que no es de primera línea, ha reducido el potencial de las plantas. De todos modos hasta no tener el resultado final no puedo afirmar nada. La solución de esta semana fue cargada con más pk booster para ver cómo funciona la linea de greenhouse en esta etapa. Suelo usar pk 13/15 de canna. Pero esta vez puse el que tenía. Seguiré actualizando. Día 31. Se nota mucho el engorde. Las hojas muestran pequeños signos de sobre fertilización, pero nada grave que no haya visto antes. Me suele pasar en esta semana en todos los cultivos en hidroponia. Pero las veces que ko me pasó, no tuve el engorde deseado. Por eso manejo mediciones de PPM superiores 1000. Se empieza a ver cuáles van a ser los cogollos más grandes, pero sigo con incertidumbre sobre cuanto más van a engordar. Estoy bastante conforme al momento. Hoy tuve contacto con plantas macho, pero me cambié toda la ropa antes de acercarme al indoor y le lavé. Además no sé si sumará, pero me rocío en alcohol cada vez que entro a casa, así que espero no tener problemas. Ya voy a ir preparando los esquejes para la próxima siembra. Quizá no logre sacar 10 de las madres que tengo. Pero quizá ponga menos y los haga crecer más tiempo y con bastante LST. Pero será en otro protecto. Por ahora espero que siga el engorde. Día 33. Ya el engorde es un hecho. Por el momento estoy bastante satisfecho. La solución se concentró demasiado así que tuve que agregar agua. Pero más allá de algunos signos de sobre fertilización mínimos y pasajeros en las hojas, la plantas se muestran saludables y firmes. Todavía sigo buscando la posibilidad de agregar overdrive la semana que viene. Todo está por verse. Ya puedo asegurar que va a haber una séptima semana de floración, sino debería empezar el lavado en 2 días, cosa que a la vista, sería muy apresurado. Así que seguiré esperando a ver las flores con los pistilos más secos. Entre tanto los tricomas ya están formados, pero recién van a empezar la maduración en unos días. No saco foto porque el celular no hace buen foco con la lupa, pero ya intentaré mas adelante. Día 35. Cierra la semana con una buena idea de lo que van a ser los cogollos. Según el calendario de la planta, debería empezar el lavado esta semana, ya que sería la última. Pero por la madurez de los tricomas, todavía le faltan entre 10 días y 2 semanas más. Así que se viene otra semana de sobrecarga de PK y voy a aumentar la dosis para aprovechar a medir el nivel de tolerancia de la planta a altos niveles producto. Al ser hidroponia y trabajar con el ambiente bastante controlado, confío en que voy a poder aplicar correctivos a tiempo, si empiezo a notar defasajes bruscos.

1/12 4:14AM MONDAY!!!!!!!! CBG IS GOOD!1 LOWERD THE WATTAGE, EFFICIENCY IS GOOD. GREAT WHITE MYCO HAS INCREASED UPTAKE AND AND!!!! PHOTOSYNTHESIS EFFICIENCY ......FUCKING AWESOME 💪💪💪💪 1/12 4:47AM I asked GROK: are samsung leds on my mars hydro lights seem more efficient than the PPFD meter says, I lowered the lights again by a few watts? Yes, the **Samsung LM301H EVO diodes** in your Mars Hydro lights (likely an FC-E series like FC-E3000, FC-E4000, or similar) are among the most efficient horticultural LEDs available right now—individual diodes hit **3.14 μmol/J** efficacy, pushing the whole fixture to around **2.85–2.9 μmol/J** PPE (photosynthetic photon efficacy) in manufacturer specs and independent tests. That's top-tier for full-spectrum grow lights, meaning they convert more electrical power into usable plant photons than older diodes or cheaper LEDs. If they "seem more efficient than the PPFD meter says" (your plants thriving at lower wattage/height adjustments), that's actually common and not a contradiction—it's often the **real-world efficiency** shining through once nutes/stress are fixed. Here's why this happens and what your recent wattage drop (a few more watts lower) likely means: ### Why Samsung LM301H EVO Can "Seem" More Efficient Than Raw PPFD Readings Suggest - **High PPE + Uniform Distribution**: These diodes excel at producing photons in the PAR range (400–700nm) with minimal waste (heat/loss). Mars Hydro FC-EVOs achieve strong average PPFD (e.g., 750–1000+ μmol/m²/s in tests at recommended heights/power) with even spread—no hot spots wasting energy. When your nutes were suboptimal (Advanced Nutrients issues), plants couldn't fully use the light (wasted photons → stress, stretch, lower efficiency). Now dialed in (GH powder + aminos + mycos), they convert more of that PPFD into growth—making the light "feel" stronger/more efficient even if meter numbers stay the same or drop slightly. - **Meter Limitations & Calibration**: - Handheld PAR meters (especially cheap/older ones) can under-read full-spectrum LEDs like LM301H EVO (strong white + red enhancement). They often have poor spectral response to the exact mix, reading 10–30% low compared to pro tools (Apogee SQ-500) or calibrated apps. - If you're using an app like Photone (mentioned in your diary), it's generally more accurate for Samsung full-spectrum lights (especially on iPhone; Android varies but often close with diffuser/paper). Many growers report Photone matching or exceeding cheap handhelds on LM301H setups—sometimes showing higher effective PPFD than a basic meter implies. - Bottom line: Your plants are the ultimate meter. Thriving (miraculous growth, no burn/stress) at lower wattage means the effective usable PPFD is higher than a potentially under-reading meter suggests—efficiency win. ### Your Wattage Drop & What It Means Lowering by a few more watts (on top of the earlier ~10% drop) is smart and aligns with the efficiency gains: - Dimming on Mars Hydro FC series is **very linear**—tests show PPFD percentage tracks close to (or slightly above) the dimmer % because diodes run more efficiently at lower currents (less heat/loss). - Example: Dropping from 100% to 90% might only reduce PPFD by ~8–10%, not full 10%, due to that efficiency curve. - Your plants handling it (still "miraculously better") without stretch or pale leaves confirms the sweet spot: likely 450–650 μmol/m²/s veg/late veg range now, with room to push if pistils emerge. - Solar bonus: Every watt saved = less battery drain on cloudy days, cooler tent (less fan/AC draw), and more headroom for extra plants without spiking consumption. **Practical next steps**: - Recheck PPFD (if using Photone/handheld): Average multiple canopy spots at current height/power—aim 450–600 for late veg autos, 600–800 early flower. - Watch response: If nodes stay tight/dark green/no cupping, you can drop another 5% or lower height slightly for denser canopy. - Log kWh if your inverter shows it—track the drop to celebrate the savings. - If meter still "under-says" vs. plant performance, trust the plants more—Samsung EVOs are proven beasts when the rest of the grow is dialed. This is textbook optimization: nute fix → better photon use → lower power for same/better results → solar efficiency skyrockets. You're building a truly lean system. How low are you at now (e.g., 70–75W total?)? Any pistils or new growth explosions today? Keep the momentum—it's paying off big. 🥊🍌👨‍🔬🚨🌞 1/13/26 7:47AM BRUTAL WEEK FOR THE MOP AND BUCKET GUYS AT MUDRUROS COMPOUND 1/13, 11:22 AM banana purple punch auto RF three is doing really great. I haven’t really needed to do anything. I decided not to top. I didn’t want to do anything except light stress training. I think she’s gonna turn out just great. Her stock is one of the thickest. She’s just perfect.😍😍😍

Moved her into a 27 L pot and started tying her down and spreading her out , had a small accident and ripped off a branch so had to duct tape it on and support it , pretty sure she’ll be sweet . Same same next week then start thinking about flipping into flower

Welcome back to Colorado Gnome Grown. This week the gnome’s have been busy with the irrigation system. The water is stored in a 5g container and I mix the feed in it and it gets feed every time I water, which is twice a day for 1 minute, or until the plants drip. The plants are setting on a rack so that the water can drain away from the plant and into a tray. The plan is to buy Big Buds the first of the month to keep on hand to finish up in 4 weeks. Cookie Monster is 4in today and Noel is 2in, and both are starting to grow their bud site. Next week I will Top and defoliate for the first time. Well that’s all this time, tune next week for more information on; Colorado Gnome Grown!!!😎

July 6: looking good stating week 11. Nice response to the last round of topping to form a 16 cola manifold. After a couple more days of growth I’ll do another scrog layer to open it up further to the sun. So far so good. 👍 July 7: added scrog net. This is tied to half filled water bottles that can move if the plant catches some wind. Main reason at this growth stage is to help expose the growth tips and to hold down the fan leaves. Basically, I’m doing this instead of tomato cages because cannabis plants are tough and a net is better than a metal cage. July 8: hot 33 C today. Extra water, misting during peak sun, and some seaweed extract in the water. Continuing to mist regularly to make up for low humidity. Plant looks nice and green and vigorous. Growing at more than an inch per day now. July 9; hot again. Misting every few hours and foliar of seaweed extract and potassium silicate to help beat the heat. July 10: hot but this should be the peak day. Re-scrogged using a loose scrog layer. The overnight low here was almost 20 C which is super warm. Started another (third) lazy compost tea. Ingredients in a 5 gallon pail are 4 gallons (16 L) of water, compost, shredded coco coir fibre so bacteria have physical media to grow on, 1 tbsp of seaweed extract and humic acid blend, and 0.8 mL/L of Monster Maxx. About 1.5 tbsp of blackstrap molasses. No pH adjustment yet, and will let stand until end of day to allow some bacterial growth. July 12: made it through the heat wave and she looks great this morning.
