**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 ! 🌱✨

Today 7/30/19, day 57 and the start of week 9. I'm still continuing to alternate between days with my pesticide treatment (especially after finding that bug living on one of hulkberries fan leaf) and thrive alive green daily foliage spray as a prophylactic solution against any possible pests or mold going into these last few dog days of veg. I will flush them with distilled ph'd water for two days this weekend in preparation for flower. Then I'll start them on some "flower fuel" bloom booster on top of my secret for success flower recipe at 1/4 of the recommended strength. Outside of that still no adverse issue to report for the end of the 8th week. After my last trim, they both have responded very nicely, I was kind of worried about fat banana stalled growth. But one thing I noticed when I topped her at the 6th node, yes the main stem stopped growing but it developed many bud sites up and down every stem. Whereas hulkberry was topped at the 8th node, she has mainly focused on developing long stems and only 2 or 3 bud sites along her stems. Even though hulkberry in structure, is much bigger than fat banana and has a way bigger root system. Fat banana is bushier and has developed way more bud sites than hulkberry. I can't tell which strain will yield the most at this point only time will tell! Also, a big shout out to "J"@RQS, thank you for the excellent customer service. Another reason why Royal Queen Seeds is top 3 in breeding!!

Hello everyone, Not much to say about this girl. This week I started giving her some nutrients so lets see how she turns out now... See you guys next week.. 🤘🤘👊👊👊

3-30-20 Yummy! That's all I can say when I open up the tent. Will up their feed strength next res change since I think they could use a bit more nutrients. 4-4-20 Week 5 coming to an end and things are looking good and smelling better! Frost is starting to pile on these girls nicely. One thing I did notice on one of the Cali Sunsets is that some of the top most leaves are starting to turn purple from the backside. Don't know if its the strain or maybe a P Def? We'll have to wait and see I guess

The seed came to me as automatic, but it wasn't presenting the sex ....

It's been another successful week.It's another successful week. The girls will soon get mineral food because the deficits are definitely too large despite the increase in food doses.💪

16 Pflanzen mit der Hand schneiden is schon ne ordentliche Arbeit, in zwei Wochen kommen die nächsten 16 🙈

So this seed is a total mystery to me. I found a loose and unlabelled seed container a while back 😭 She will be grown on 20/4 light and we will see in week 3~4~5 if she is an auto or not. She is planted in a tiny 1 litre airpot, where she will stay throughout her life. I have no idea what kind of plant to expect from this, so here we go!

Plant is doing amazing! This is my first grow & I am so excited , I’m in the process of practicing LST , I am not the best but you learn as you go! Let me know what you all think! She seems healthy to me

Bajé la dosis de agua de llave a purificada en 1/3 del total. Dejé de utilizar top roots y están prontas a floración. Las ultimas tres fotos corresponden a una defoliación.

7th week began today(Day 42). Girls are looking healthy and nice. They have devoured the whole growing space by now. The one on bottom right lost most of its roots while transplanting because of my mistake. She has made an incredible fast recovery, some of her leafs fell after the incident but she has now reached almost the same size as the others. * Is outdoor plant that was saved from the forest when the weather began to go too cold for hemp to develop any further. She is now inside since 3 weeks and is due to ripen in one week or so.

Plants looks healthy, they are really in good shape and cover aproximietly 1m2 each plant. They looks amazing :)

We have made it to day 42! 31/12/20 All the girls have started flowering now! I'm super keen to see them start to thicken up. Feeding as usual, nothings changed. Update - day 46 04/01/21 I'm a little concerned about the 2 runts that were laggin behind the rest, all of a sudden theyve decided they want to take up most of the room in the tent. I've never grown autos so big.. I was contemplating putting the runts outside but it's just going to make more problems as my outdoors are under attack from some kind of bug. I will keep the diary updated on the runts, other than that the other girls are doing just great, flowering is really coming along. Thanks for stopping by!

Only water filled up again. 💦 Due to the rather humid living soul substrates, a few fungus gnats

Es ging stetig bergauf in Woche 2. Geplant ist toppen und später ein scrog zum stützen und zum Angleichen der Höhe. Der Wurzelstimulator von House & Garden performed mMn sehr gut, keinerlei negative Reaktion der Pflanze. An Tag 15 wird getoppt und dann bin ich gespannt auf die Blüte.

I am very satisfied with the germination that took place in a few days. 🌱💪 This week I will continue to keep an eye on the development of the plant to prevent it from stretching too much in the first weeks. 🔍 I use BioBizz Light soil which for the first few weeks manages to provide enough nutrients, so I will water with a little water every day, to keep the humidity a little higher, without running the risk of overwatering. 🌊❌

Growing strong cut 13clones today and transplanted the two biguns loving how they are turning out
