Atzengrow Z-Up – Week 1 (Germination Phase) The Z-Up is still at the very beginning: The seedling has just become visible and has barely broken through the soil. This stage is extremely young, so it's especially important to: • Not let the soil dry out • But also not to overwater • Gentle, but constant light In the next 1–2 days, the cotyledons should be fully visible. The emergence looks stable and well-established. Your buddies

Atzengrow Z-Up Auto – Week 2 The Z-Up is going strong into week 2. The seedling has developed its first true leaf pairs and is stable in the substrate. The stem is short, compact, and shows no stretching – a good sign of sufficient light and a stress-free environment. Growth is still slow at this point, but the structure looks healthy: deep green coloring, no burn marks, no spots. The soil is evenly moist, and the root area seems to have gotten off to a good start. In week 2, it’s mainly about establishing a strong foundation before the actual stretch begins. Currently: • Light intensity is on point (no stretching). • Fertilization is not necessary – it’s still drawing everything from the soil. • The moisture zone around the stem is well established. • Humidity is in the target range. If it keeps this up, you should see the second leaf pair fully open by the end of week 2 – then it will switch into early veg mode and visibly grow. Your buddies

Atzengrow Z-Up – Blütewoche 5 In Blütewoche 5 zeigt die Z-Up eine klar strukturierte Pflanzenform mit mehreren gleichmäßig entwickelten Colas. Die Buds sind kompakt angelegt, jedoch noch im Aufbau begriffen. Die Kelche beginnen sichtbar anzuschwellen, während ein hoher Anteil der Stigmen bereits orange bis bräunlich verfärbt ist. Die Trichombildung ist deutlich ausgeprägt und überzieht die Blüten sowie angrenzende Zuckerblätter mit einer geschlossenen Harzschicht. Auffällig ist die ausgeprägte Chlorose im unteren und mittleren Blattbereich. Große Fächerblätter zeigen eine starke Gelbfärbung mit partiell verbräunten Spitzen und Rändern. Die oberen Blätter wirken heller grün, teils mit leichtem Spitzenbrand. Trotz der deutlichen Blattveränderungen bleibt die Blütenstruktur stabil, und die Buds entwickeln sich gleichmäßig entlang der Triebe. Entwicklungsschwerpunkt dieser Woche: • Fortgeschrittene Blütenausbildung mit zunehmender Harzproduktion • Deutliche Blattvergilbung im unteren Bereich • Gleichmäßige Cola-Entwicklung bei stabiler Gesamtstruktur Eure Atzen

Atzengrow Z-Up – Flowering Week 7 The Z-Up shows significantly advanced flower development this week, with compact, well-formed buds along the main and side branches. The flower clusters appear dense and evenly distributed, with several medium-sized colas formed. The surface of the buds is visibly covered by an increasing layer of trichomes, giving a distinctly resinous impression. Some of the stigmas have already taken on an orange to brown coloration, while a few lighter threads are still present. The leaf structure shows pronounced yellowing of many fan and sugar leaves, especially in the upper part of the plant. Despite this color change, the overall structure remains stable, and the buds retain their compact shape. The plant presents itself as rather short and bushy with several evenly developed flower sites. The flowers appear increasingly dense at this stage, while resin production continues to intensify and the flower structure remains clearly defined. Focus of development this week: • Further densification and weight gain of the buds • Noticeably increasing trichome formation on the flowers • Significant yellowing of the leaves in the late flowering phase Your homies

Atzengrow Z-Up – Flowering Week 8 The plant is in a late flowering phase with well-developed, compact buds. The main colas are noticeably dense and show an even structure with pronounced resin production. The trichome coverage is visibly high, giving the flowers a matte, slightly "frosty" surface. A large part of the stigmas has already changed color (orange to brown), while only a few fresh, light hairs remain. The leaf mass shows an advanced degradation process. Many fan and sugar leaves are heavily yellowed, some with necrotic tips and curled edges. The buds themselves remain stable and compact, while the plant overall exhibits reduced vitality in the leaf area. The structure is low and bushy, with several evenly developed side branches that carry dense, medium-sized flowers. Development focus this week: • Advanced ripeness with predominantly discolored stigmas • High resin production and stable bud density • Significant leaf degradation and pronounced yellowing throughout the canopy Your homies
