**Semaine 5 : Cinquième Semaine de Floraison – Phase Bulking (18-24 mars 2026)** **Note :** transition réussie vers le bulk végétatif. ### Contexte et Objectifs de la Semaine Semaine 5 = entrée franche dans le **bulking** pur. Le stretch est terminé, l’énergie est désormais massivement redirigée vers le gonflement des buds, la production de trichomes et l’accumulation de masse/resine. Steering : **végétatif confirmé** (irrigations fréquentes, runoff 20-30 %, dryback contrôlé mais moins agressif que pendant le stretch, VWC plus stable). Objectif principal : maximiser le volume et la densité des buds tout en maintenant une santé parfaite jusqu’au pic de résine (semaines 6-8). **Petit point éducation + tips sur la fin du stretch et le passage en bulking** - **Fin du stretch** : chez la plupart des variétés hybrides/indica-dominantes comme Sticky Broccoli, le stretch s’arrête ou ralentit fortement entre la fin de semaine 3 et milieu de semaine 5. Ici, seulement +10 cm cette semaine (vs +20 cm/semaine auparavant) → c’est **parfaitement normal et souhaitable**. La plante a fini d’étirer ses entrenœuds et passe en mode « remplissage ». - **Pourquoi les buds grossissent maintenant + trichomes apparaissent** : La combinaison steering végétatif + EC 2.6-2.95 + PK 13/14 + Sugar Royal + Green Sensation + enzymes + CO₂ 900 ppm + DLI 32 + UV 45 min/jour crée un environnement hyper favorable à la division cellulaire et à la biosynthèse des cannabinoïdes/terpènes. Les trichomes (glandes résineuses) commencent à se multiplier et à grossir dès la semaine 5 chez les génétiques résineuses. C’est le moment où on voit la plante « s’épaissir » vraiment. - **Tips concrets pour maximiser le bulking** : - Ne pas monter l’EC trop vite (3.2-3.4 risque de lockout léger en coco) - Garder le VPD jour 0.9-1.2 kPa et nuit 0.8-1.1 → transpiration optimale sans stress - Augmenter progressivement l’UV (45 → 90 min/jour en semaine 6) pour booster terpènes et THC - Surveiller le runoff pH (idéal 5.8-6.2) → si il descend sous 5.7, petite montée pH solution 0.1-0.2 - Photos tous les 2-3 jours pour détecter tôt tout jaunissement bas ou pointe de feuille qui brunit ### Observations des Plantes - **Plante dominante** : a clairement pris le dessus. Hauteur actuelle **~1m50** (seulement +10 cm cette semaine). Stretch terminé, structure très grosse et aérée, canopée dense mais bien pénétrée par la lumière. - **Buds** : commencent à vraiment grossir, les calices s’épaississent, premiers trichomes visibles à l’œil nu sur les buds supérieurs (légère brillance sucrée). Pistils encore majoritairement blancs mais commencent à s’enrouler légèrement. - **Vigueur générale** : excellente, vert profond, pas de carence visible, pas de burn, pas de pest. La plante secondaire est plus petite mais suit bien. Clones toujours très sains. - Zéro signe de stress, plantes en pleine forme et concentrées sur le remplissage floral. ### Paramètres Environnementaux (TrolMaster + GrowOps – synthèse 18-22 mars) - **Température jour** : 23-25 °C (cible actuelle 23-25, leaf temp ~24-27) - **Température nuit** : 18-20 °C (cible 18-20) - **Humidité jour** : 64-74 % → baisse progressive vers 60-70 en fin de semaine - **Humidité nuit** : 49-59 % - **VPD** : 0.8-1.2 kPa jour/nuit (stable et optimal pour bulking) - **PPFD moyen** : ~733-750 (max ~814) → DLI ~32 mol/m²/jour (parfait) - **UV** : 45 min/jour (prévu +45 min en semaine 6) - **CO₂** : setpoint 900 ppm jour (non mesuré précisément mais actif) - **EC solution** : 2.6-2.95 mS/cm (baisse légère récente à 2.6) - **pH solution** : 5.8-6.0 (runoff 5.8-6.2) - **Irrigation** : Fréquente, runoff 20-30 % quotidien - **Steering** : Végétatif (confirmé) - **Night dryback** : 8-12 % (très contrôlé) ### Problèmes et Ajustements Aucun problème majeur. - Légère baisse EC feed (de ~3.0-3.4 → 2.6) : volontaire pour éviter accumulation en coco pendant le pic de bulking. - Température jour un peu haute par moments (25-27 leaf) → surveiller pour éviter stretch résiduel ou transpiration excessive. - UV à 45 min → bonne montée prévue semaine 6. ### Plans pour la Semaine 6 - Continuer steering végétatif + possible petit pic EC/PK si buds semblent ralentir. - Augmenter UV à 90 min/jour. - Légère défoliation sélective (feuilles qui bloquent vraiment la lumière sur buds inférieurs). - Photos rapprochées pour suivre trichomes et gonflement. - Préparer clones mères si sélection finale. Ce journal sera mis à jour hebdomadairement. #GrowLegendary #Zamnesia #Plagron #EternityGrowCup2 Les buds prennent vraiment du volume maintenant, la plante dominante est impressionnante à 1m50 et les premiers trichomes visibles → ça sent le gros rendement qui arrive ! 🌱✨

Finished 5 week of 12/12 and it finally started to show some preflowers 👏👏 girls are very bushy and starting to stretch a lot but they have so many new branches that I have a feeling it’s gonna be monsters:) Looking forward to next few weeks 👍

🔥🍇🌋

She got really nice citrus smell and perfect bud structure. Trichoms looking gorgeous 😍😍😍👌👌👌

Wow she's looking lovely this week!! Starting to smell too, quite fruity/pungent! 😎

Well, this is week five and these lovely ladies are taking off. The only problems I have had (knock on wood) was the autopots valve sticking and flooding occasionally. I think I have them figured out though. Customer service from them is amazing. I will as always update throughout the week. Take care and happy growing. 🙂

Welcome growfessors to another episode of growfessor theatre 👽💚 Week 6F begins for the ladies of the 4x4, Green Crack, LSD and Mandarin dreams are rocking! Buds a bulking up, getting sticky, frosty and stanky!! Do-si-dos is a bit behind the other ladies as this strain will take an extra week to finish, but she's also packing on size, frost and stickyness. The Mars-Hydro TSW2000 light is rocking the grow, lighting up the 4x4 really well! Thanks for stopping by growfessors, stay tuned for another episode! 👽🌳💚

Hi guys! I update you with my beautiful gorilla glue! we are at 5 weeks of vegetative growth and the plants seem to be doing well! we are preparing for flowering 😁 in the video there is also the small grow box which is already in bloom😅❤️ thanks to all and good comtivation❤️😘

Day 45-52 (Day 46) I just realized I forgot to zip up a small flap in the tent for at least 5 days or so. This probably made the added co2 useless. All the plants are slightly clawing and almost look overwatered, which is normal for plant at this stage but I wonder if the lower co2 levels are contributing at all. I couldn’t help myself today and did a small defoliation. Hopefully this doesn’t stress them out too much. I took about 15-20 leaves per plant. I really want some of this larf on the bottom fill out more. Even by 10-15%. (Day 47) Wow. I just noticed that #5 is putting on a thick layer of late frost. I’m guessing this has to do with all the mid flower feedings. Unfortunately the density on this girl lacking big time. Especially on the lowers. This could be genetic but there is too many variables at play to say for sure. If this stuff smokes proper I will continue to feed in mid flower. Plants are really starting to fade out here now. #3 in particular has some odd red coloring in a few of the leaves. (Day 48) I watered in 2 gallons on each plant making sure to get some decent runoff from each. Sucks that #3 didn’t fill out. The genetic potential was definitely there, something just went awry after that tea I gave it. I have at least 2 or 3 clones of that I will try outdoors. It’s been a very P hungry plant too. The stems were purpling like crazy, even in veg. Some people say this can be fixed with a microbial product like Mammoth P or Tribus which I might try for my next grow. #6 isn’t really filling out much either unfortunately. Tops look decent but everything under that is pretty leafy and airy. #1 and #7 are the clear winners here. #1 especially is picture perfect. If I wasn’t working on another project after this I would clone just #1 and run another scrog like this from clone. (Day 50) I was plucking some leaves today and I found a confirmed banana sticking out of one of the main colas on the stubby pheno. I didn’t defoliate this one too much so I wonder if it was caused by stress at all. I hope I don’t find anymore because we only have 10 days left here. (Day 52) My family member trimmed up the m39. It looks super scraggly but has some decent crystal nonetheless. That’s partly why I would never use an amazon blurple for flowering. It just doesn’t have the same canopy penetration that a light like mine does. Although for a budget setup they’re pretty awesome.

Week 5 of flower for the frozen black cherry. She is growing big! She has a lot of budsites and large and thick pistil hairs, which usualy means big buds. She is however still on the low side when it comes to trichomes. They are coming, but very slow. Because there is not a lot of trichomes yet, there is also not a lot of smell yet. I am not used to this being the case, so I am stressing out a little over this one. But on the other side, she seems like she is going to take her time. So we will just have to wait and see 😶‍🌫️

Time too flush this lady for two weeks if she allows All went fantastic and the green buzz nutrients range has performed , This lady will be coming down very soon , Really packed on weight and trics are 100% cloudy , just waiting for a few more amber's , I suspect she will be finnished within the next 7 days

This was a week. The drama at the beginning was one of the fans falling down onto my gorilla cookies. It snapped a branch off really bad but the girl hung onto it by threads. I duct taped her up and somehow took. 😎😢 I defoliated and did a little lst on a couple of the girls. Nothing major. Also increased the light to 80% now. I think I'll stay there until late flower when I switch to 12/12. I also added blocks to a couple of the girls to make the canopy level. That put the light at 15" as recommended by Medic Grow. Purple Lemonade is slowly making a comeback. I will say, even though the buds are small and the plant has struggled, the smell is already there. Which excites me. The lemonade smell is definitely there. Dimmed to 80% Here are the lights details: Medic Grow Mini Sun-2 150W LED Model: MN150-022 Spectrum mode: V1 Efficacy: 2.8 umol/J Thanks for stopping by!

harvested on day 66. trichomes been turning amber for last couple of weeks. but she is amazing. bud structure is top notch and the smell is unreal. this was my first organic grow and only second ever. the difference in my grows are night and day and i will be staying organic for sure. i cant recommened it enough. will update weights etc when its all dried hopefully on the weekend coming

That was the most difficult week. It was very cold and rainy, the humidity of the air reached 90% at most, but without sequels, thank God. On day 63, I defoliated and she is strong, fat and definitely smells like cheese.

Amnesia Zkittles still going….. All the rest are in the freezer except a few saved buds of cherry cola. I’ll be making hash with them

This is where we are at .. I don't know if I should cut the bigger leaves to help with energy 🤔

I'm surprised 😮 about the difference between now and last week ...they became really 😳 monsters 👻 👽 I'm very happy with this grow I can say #RipperSeeds are one of the best 👌

Fantastic run!!!! Lots of fun BeLeaf cultivars ROCK!!!

Lots of stretching this week, been having fun LST ing the poor girl Given two feedings again this, no signs of nute burn. Day 24 Dr FG 2ML Grow 1 TSP Molasses 1ML Calmag 1 litre water Day 26 Dr FG 2.5ML Grow 1ML Bloom 1ML Calmag 1 litre water
