Semaine 6 – Transition Floraison : Pistils et Défis Nutritionnels Jour 35–41 (17 avril – 23 mai) La semaine 6 marque officiellement l’entrée en floraison. Gorilla Cookies a ouvert le bal avec ses premiers pistils la semaine passée, suivie par Toof Decay. Les autres génétiques (Mephisto’s Wedding, Hubbabubbasmelloscope) montrent des signes avant-coureurs de floraison. L’environnement reste stable : 24–25°C, RH 62–64%, VPD 1.17–1.21 kPa, conditions proches de l’idéal. Nutrition et PPM Transition vers Bud Ignitor (1 ml/L) et maintien du GMB 1:1:1 à 1.5 ml/L. Cal/Mag augmenté à 2 ml/L. = ~570–610 ppm réels. Problèmes identifiés Carence en Cal/Mag sur Hubbabubbasmelloscope et Gorilla Cookies (chlorose interveinal, feuillage jaune). Traitement direct : 2–3 ml/L Cal/Mag appliqué par pot. Réaction positive après 3–4 jours. Observation critique : les 4 plants en AutoPot (AQUAValve 5.0) montrent 2x moins de vigueur que les 3 plants en bases AC Infinity avec les pots en tissus. Hypothèse : le système AQUAValve maintient le substrat trop humide en continu, tandis que les bases AC Infinity crée une meilleure oxygénation. Aussi, c'est seulement sur les auto pots que j'ai observé des carences, peut-être dû à un blocage nutritionnel. À évaluer pour les futures canopées. Lumière et PPFD IF500 (500w) + Mars Hydro 500w maintiennent 660–700 µmol. Pas de stress lumineux, feuillage bien coloré (sauf carence identifiée). Statut réservoir 47L, 15L pots coco 100%. Consommation d’eau stable. Changement complet prévu mi-floraison. Prochaine semaine : suivi de la carence corrigée, ajustement graduel du calendrier nutritionnel Advanced Nutrients pour la phase de développement floral.

Timing AutoPot précoce→ Plantes jeunes, consommation faible 2. Eau restante dans les pots → Contact prolongé avec air dômes 3. Air dômes + coco neuve → Oxydation progressive, dérive pH vers alcalin 5. pH 6.8 en coco→ Blocage d’absorption de Cal/Mg (disponibilité réduite de 40–50%) Résultat : Symptômes de carence alors que les nutriments étaient présents = blocage nutritionnel, pas déficience réelle SOLUTION APPLIQUÉE Étape 1 : Correction immédiate (24 mai) - Prélèvement eau au fond des 4 pots AutoPot - Pompage progressif jusqu’à pH 5.8 - Volume pompé : ~1-2 L par pot (estimation) - Nouveau pH : 5.8 stabilisé Étape 2 : Traitement localisé (jours 20–24) - Application directe Cal/Mag : 2–3 ml/Lpar pot (non-réservoir) Top wathering - Appliqué sur : Hubbabubbasmelloscope Mephisto, Gorilla Cookies Fast Bud - Méthode : versement manuel aux racines - Fréquence : 2 applications espacées de 3–4 jours Étape 3 : Maintenance réservoir - PPM réservoir principal : maintenu 400–420 ppm (Hanna HI98301, scale 500) - Note calibration : Vrai PPM = lecture × 1.4 = ~560–588 ppm - Cal/Mag réservoir : maintenu à 2 ml/L - pH réservoir : vérification quotidienne post-correction Étape 4 : Surveillance continue - Routine hebdomadaire établie : Prélèvement fond pots, vérif pH - Objectif : Détecter remontée pH avant accumulation - Seuil intervention : pH 6.2 = pompage correctif RÉSULTATS & OBSERVATIONS Court terme (5–7 jours post-correction) - Pistillage accéléré visible sur Gorilla Cookies (confirmé jour 37) - Décoloration n’a pas progressé → blocage levé - Plants Mephisto’s Wedding : vigueur stable (10% affectés) - Toof Decay : vigueur stable (10% affectés) Comparaison système Observation importante : Plants en bases tissu AC Infinity (manual feed via bleed valve) montraient plus de vigueur que plants AutoPot - Raison probable : Cycle humide/sec régulier vs eau stationnaire - Implication : AutoPot inadapté pour timing de croissance lente initiale LEÇONS APPRISES Sur le système AutoPot 1. Activation tardive recommandée→ Jour 25–30, pas jour 17 1. Monitoring pH hebdo obligatoire → Coco + air dômes = dérive pH naturelle 1. Eau stagnante = problème→ Même avec nutriments corrects, pH alcalin = blocage Sur la coco neuve - Nécessite ajustement pH plus fréquent en début - Se stabilise après 3–4 semaines d’utilisation - Minéraux s’accumulent lentement → nettoyage hebdo bénéfique Choix système pour Run #3 AutoPot déclassé pour prochaines runs - Passage à : 8× bases AC Infinity + 8× flottes automatiques individuelles - Avantage : drainage régulier, pas de stagnation, PPM/pH plus stables - Setup réel : coco/Bio-Urbain, 5 gallons, 75L réservoir centralisé DONNÉES COMPLÈTES CONCLUSION Problème :Eau stagnante + pH alcalin = blocage nutritionnel (pas déficience) Solution : Correction pH + Cal/Mag localisé + routine hebdo de monitoring Statut : Résolu, plants en rétablissement, early flower progression normale Impact rendement : Minimal — correction avant dégâts sévères

Hey growmies, here we are into last week before Flushing these beauties.. I have stopped tripart 3part nutrients and they are now on ripen (final part).. 5ml per ltr. =100ml per 20ltr tray. The buds are swelling up and the aroma from the grow room is amazing 👏 😍 the grape gushers remind me of a solid dense pyramid shaped bud site.. Where as the the wedding cheesecake bud sites are very much like the purple lemonade I have just harvested... I have a feeling I am going to be surprised by the final dry weight as all bud sites look absolutely amazing.. Thanks for checking in!!

Week 7 day 3. I stopped giving soluble nitrogen today. 1/2 reduction in soluble pk. Adding solubles in water drops my ph perfect so I don’t use ph down in flower. Now today I start adding a little ph down as the 1/2 strength soluble pk brings water to about 7.4, so reduction to 6.9

Six weeks ago I flipped the light to 12/12 and I got to say it’s pretty fast growing. Trichomes looking good. Harvest get closer and closer. 4 of 5 plants are colouring pretty hard. Nice bud to leaf ratio and overall nice appearance. This week I started to lower the temps for terpene preservation. Smell is quite skunky and a little bit fruity.

My Northern Lights number 10 plant is the biggest in the tent so far, and it's stacking like crazy. I love the short leaves – they're perfect for fitting a bunch of branches into a small space, even though they're really big. It's been a challenging week with the constant rain and ridiculously high humidity. Keeping things dry indoors has been a real struggle. Despite the weather, I managed to flip all my feminized photoperiod plants to flower this week. I'm hoping the switch will go smoothly, but with this humidity, it's going to be tough.

These have surprised me , not even a spot on them. Wall to wall now , maybe should have went with a total of 7 , but im not complaining . Few of these are already dripping in thc . The two largest ones were topped , I have done a defol on them , the smell is definitely there . I might need a filter in the next few weeks .

Good week. PPM issues last week were due to messing around with the watering schedule. I changed to a 3min fill and the extra water disturbed the clay pebbles, releasing sediment into the reservoir. I'm back to 1min fills. Buds are looking excellent. They're growing very close to the lamp but I don't have room to raise it anymore, I'm thinking I'll need to string them using the corners of the tent as anchors if they start burning. The dehumidifier was also set too high, so it's been a bit steamy in there for the last day. Reset it from 45% back down to 20% so it's running at full power day and night. When it's set at 45% the real RH raises to 80%, when it's set at 20% the RH sits at around 45%.

Day 19. Another defoliation. Watered in a gallon from the top. Then topped off sip buckets.

Started the flush a few days ago. Wish I had set up a second scrog. The branches are falling over under their own weight - hence the makeshift netting.

White Widow looks realy good. I expect that I can harvest her in august. Northern Lights looks good too, but seems to be flowering much slower then White Widow. Blueberry Ghost OG (it is HUGE already) and Kali AK still won't start flowering and I don't know why.

FBT2308 is growing great under the Medic grow Mini Sun-2 in the Agrogardens nutrition. She has huge leaves, and is starting to stack her colas now. It is looking like she wants to produce a lot of flower from the pistils forming. I add more nutrition when I added water. Possibly help curb the minor issues on bottom leaves up from spreading. She had some selective defoliation around center to let more light, and air in. She us looking great. Thank you Medic Grow. Agrogardens, and Fast Buds. 🤜🏻🤛🏻💪🏻❄️🌱 Thank you grow diaries community for the 👇likes👇, follows, comments, and subscriptions on my YouTube channel👇. ❄️🌱🍻 Happy Growing 🌱🌱🌱 https://youtube.com/channel/UCAhN7yRzWLpcaRHhMIQ7X4g
