🌱 Woche 2: VPD-Chaos, Licht-Optimierung & Nährstoff-Update Ziel: Stabile Veg-Bedingungen für die #CannabisCup-Kandidaten! ⚡ Highlight der Woche ✅ Licht-Perfektion erreicht! PPFD: 450–550 μmol/m²/s (mittig 550, außen 450) durch Neigung der LED-Panels → gleichmäßige Ausleuchtung (siehe Bild). Lampe: 55 % Leistung – ideal für die Veg-Phase. 💥 Drama & Lösungen 1. VPD-Absturz (0,27 kPa): Ursache: Luftbefeuchter-Fehler → zu hohe Luftfeuchte (RH 90 %). Folge: Lemon Cherry Salts legte sich hin (KO Counter: 2), Radical Juice blieb stoisch. Fix: Befeuchter-Reset + Lüftung hochgefahren → VPD stabil bei 0,8–1,0 kPa. 2. pH- & EC-Management: Autopots: EC 2,0 | Handwatering: EC 1,6 pH-Anstieg im Reservoir (6,4 → 5,7): Manuell korrigiert – jetzt alle 2 Tage prüfen! 🔬 Technische Daten Parameter→→→→→→→→→Wert→→→→→→→→→→→→→→Zielbereich PPFD→→→→→→→→→→450–550 μmol/m²/s→→→→→→→→300–600 (Veg) EC (Autopots)→→→→→→2,0 mS/cm→→→→→→→→→→→→1,8–2,2 pH(Reservoir)→→→→→→→5,7 (stabil)→→→→→→→→→→→→5,5–6,0 📈 Fazit nach 2 Wochen: Autopots liefern dank konsistenter Nährstoffversorgung und keinem pH-/EC-Stress das reinste „Set-and-Forget“-Veg-Wachstum. Handwatering-Gruppe kämpft noch mit den Folgen des frühen Nutriburns (RIP Woche 1 😅), holt aber langsam auf.

Spotted on 2 Plants Yellow Spots on the leaves. Not a major issue but i want to try my best that they recover before i send them into Flower.(+2Weeks) Had some VPD (leaf Temp 23°C, 61% Humidity - now 53%) issues the last couple of days and ramped up my light to 600-800 PPFD.

Everything is looking good to me. The yellow spots could be due to the light increase. The plant is only a couple of weeks old. Continue to observe and watch. It doesn’t need continuous tweaking.
