Lighting and Growth Transition: I switched the bloom light to a 12/12 rhythm, transitioning to a night schedule through an extended day cycle. The next day, I increased the light intensity to 70% (140W) from the previous 40% (80W). This week has gone well, and the plants have started to stretch significantly, doubling in size. Despite the topping, tying down, and light manipulation to keep them compact with many nodes, the plants are now showing rapid elongation with short internodal spacing. Early Flowering Signs: On Day 5 of the flowering stage, I noticed the first small buds, and by Day 6, the first calyx with pistils appeared. As flowering began, I removed the LST wires, allowing the plants to grow almost straight up with 5-6 main stems each (one stem broke during training on Plant #2, while Plant #1 has 6 main tops). Humidity Concerns: The humidity in Germany is high, and I would prefer it to be below 70%, but it has been raining continuously. The canopy is developing nicely and evenly. I am concerned that my decision to lollipop in Week 2, combined with high humidity and a full tent, might lead to mold. However, this week looks good so far. I am vigilant about checking for water accumulation between leaves. Nutrient Management and Issues: An unexpected issue arose: yellow tips on the leaves of #2. Biobizz Acti Vera contains a high iron content, but the deficiency is evident. Since the plants were watered the day before, I suspect the problem lies there. As it has only affected one plant, I am not overly worried and will increase the iron content in the next feeding while reducing phosphorus and potassium as planned. I will skip Cal-Mag since these elements compete with iron, which must be sufficiently present. Nutrient Strategy: I suspect that the phosphorus boost I previously gave disrupted the soil dynamics (this is a new technique recommended by an experienced grower, though I am unsure if it applies to mineral or organic fertilizers). There are two options and one solution: wait and adjust the nutrient balance. Since I use minimal fertilizer but add it at every watering to maintain bacterial and fungal populations, I will avoid flushing and aim to provide fewer nutrients. BioBizz Grow has been reintroduced. Watering Schedule: The plants need watering every 2 to 3 days, so any changes in nutrient levels won't be noticeable within the week.
