That much is beyond senescence. But, the time to do something was when the symptoms were progressing. There's no healing necrotic plant tissue. The red color can be ignored, unless you unintentionally allowed temperatures to drop below 18c / 64F. Low temps will exaggerate "Fall" colors. Plant biology struggles at colder temperatures. Sometimes the Fall colors just happen due to genetics even if temperatures remain in a good range. Your dairy week from "19 days ago" shows some potential N-deficiency and start of Ca deficiency, i'd wager. Leaf symptoms are indiscrete, so you typically need more information to be confident. These 2 are a bit more obvious than others, but that doesn't mean it wasn't lockout of some sort.. usually lockout has symptoms that are confusing or a smorgasborg of issues... always need to cross-reference more info to diagnose properly and can still be wrong at times. Week 2 also shows likely bad watering habits, which over time can definitely contriubte to problems later on even if it doesn't cause a problem initially. Hard to say if 5-3-2 is a good ratio as your soil contents are a guess and possibly exhausted late in flower anyway. On its own, 5-3-2 is not a good ratio. if not using readily plant-available N upon dilution, 2-1-2 is a better ratio and late in flower you want less N. What 'should be' is all fine and good but always react to the plant in front of you regardless of what 'should be.' A deficiency or toxicity simply needs to be counteracted, regardless. Lockout needs to be remedied. The plant definitely shouldn't be near-dead or have a decimated canopy before the flower ripens. that's not senescence. that's senescence exaggerated by not providing nutrients to the plant. If you use the same products, soil and keep track of your fertilization over time, you can review, adjust and do better next time. Anytime you change the soil, you'll have a new learning curve, but it gets easier each time. Fertilizer brand won't matter much, but whether it's for soil or soilless/hydro does make a difference.

salut. désolée la réponse vas être longue .en effet c'est pas très bon signe .je vais essayer de t'expliquer au mieux .je comprends ton inquiétude. Ta plante n'est pas "en train de mourir" au sens littéral immédiat, mais elle est en souffrance critique, c'est extrêmement urgent d'agir pour sauver ta récolte. ​On est bien au-delà de la "sénescence normale". C'est une carence massive et un blocage nutritif sévère. Voici le diagnostic et le plan d'action d'urgence : ​1. Le Diagnostic : Carence complexe et blocage ​En regardant vos photos, en particulier image_8.png et image_4.png, on voit plusieurs problèmes combinés : ​Sénescence foudroyante : Tes têtes principales (image_8.png) sont presque "cuites". Elles sont brunes, sèches et les feuilles s'enroulent. C'est le signe que la plante n'arrive plus à s'hydrater ni à se nourrir correctement. ​Carence en Phosphore (P) & Potassium (K) avancée : La couleur jaune/brune et les feuilles qui se recroquevillent sont typiques d'un manque criant de P et K pendant le gonflement des têtes. ​Blocage du Zinc/Fer : Les feuilles jaune vif du haut (image_5.png et image_6.png) avec des veines encore vertes et des taches de rouille indiquant un blocage de ces micronutriments, souvent dû à un pH du sol complètement déréglé. ​2. Le Plan d'Urgence (Dès maintenant) ​Si tu ne fais rien, tes têtes vont finir de sécher sur pied et deviendront impropres à la consommation. ​Étape 1 : Le Rinçage Correctif immédiat. Tu dois "laver" ton terreau. Utilisez une eau pure (sans engrais), idéalement du robinet laissé reposer 24h, et surtout ajustez son pH à 6.2-6.5. Arrosez généreusement jusqu'à ce que 20-30% de l'eau s'écoule du pot. Cela va évacuer les sels accumulés qui bloquent les racines et rétablissent un pH sain. ​Étape 2 : Vérifie l'humidité. Avec des têtes aussi sèches en haut mais généralement humides en bas, le risque de moisissure (Botrytis) est immense. Assure-toi que ton extracteur tourne à fond et que ton ventilateur de brassage tape direct sur les têtes. ​Étape 3 : Adaptez la lampe. Si ta lampe est trop forte, elle "brûle" les têtes sèches. Éloigne-la légèrement ou réduis son intensité à 50-60%. ​Étape 4 (Le prochain arrosage, dans 2-3 jours) : N'utilisez PAS d'engrais "Grow". S'il te reste 1 ou 2 semaines avant la récolte, s'arrose uniquement à l'eau pure fusion. Si tu es encore à plus de 3 semaines, prépare un mélange très léger (1/4 de la dose) d'un booster de floraison (style PK 13/14) avec ton eau au pH ajusté. Mon verdict : ​Tes têtes principales sont sévèrement touchées. Le but n'est plus d'avoir une récolte record, mais de limiter la casse.En rinçant maintenant et en stabilisant le pH, vous permettras aux têtes du bas de finir de mûrir correctement. ​Surtout, inspectez vos têtes brunes au cœur pour vérifier qu'il n'y a pas de moisissure grise à l'intérieur ! j'espère que j'ai pu t'aider. bonne journée.

Fried weed anyone.. No seariosly that's well over fed with too strong a light or you have sprayed with something.. Probly when lights are on.. You can over feed in living soil its easy too I fact, not knowing what is in the soil then adding more is having loads of one mineral and not enough of another..you use a nutrient line that is all. Not living soil u till it's colanised with microbes so I recomend a microbe inoculant like mammoth p... Sorry not looked at your diary but can see some1 mention npk values, not in my living soil thanks.. Look after the soil and she will do the rest. Salts will only kill off the microbes that are doing the heavy lifting.. Good luck.

That’s more than normal fade the heavy yellowing, curling, and browning suggests serious nutrient deficiency or lockout (likely high/low pH or salt buildup), so yes, act now with a flush and reset your feeding

It’s called the senescence…. It’s normal… it’s part of the end of its life cycle.

As you grow in living soil, I would not look at over-/underfeeding or lockout at first. Is it possible that this is wind damage from the vent? The vent looks huge and close. Even if it is oscillating, that might be too much for the plant. It is called wind-burn.

Do you give her still nutriends? If you do so, you might have a lockout. Did you check trichomes to estimate how long they need from now?
