Week 25 is rolling along on the deck, and the Durban Poison photoperiod crew is putting on an absolute masterclass in outdoor structure and flower development. Sitting comfortably in their large fabric bags on furniture dollies, these sativa powerhouses have built an incredible network of robust colas that are packing on serious weight and density as the late-season bloom cycle intensifies. Managing this stage successfully comes down to dialing in the right balance of organic amendments, micronutrients, and water chemistry to keep the root zone happy without causing nutrient burn or pH lockouts. Nutrient Management & Feeding Routine * Seabird Guano (0-11-0): Playing a starring role in the heavy bloom phase, the high-phosphorus seabird guano provides the essential P needed to drive massive flower set and resin production. Following top-dressing routines like the recent application on August 2nd, this amendment fuels the explosive bud development visible across the upper canopy. * Kelp Meal: Espoma Organic Kelp Meal works in tandem with the soil to supply essential natural trace elements, potassium, and growth hormones that boost plant stress resilience against shifting late-season outdoor temperatures and wind. * Cal-Mag: Essential for preventing secondary nutrient deficiencies, calcium and magnesium keep the cell walls strong and support the heavy metabolic demands of these sprawling sativa colas. * pH Down & Water Balance: Balancing out the hard tap water requires careful monitoring. While source water sits around a 7.5, keeping a close eye on the General Hydroponics pH Down ensures the root zone stays optimized for maximum nutrient uptake without inducing sudden pH crashes. The canopy is looking exceptionally vibrant, vigorous, and primed for a heavy, aromatic finish as harvest window approaches. The aroma on the deck is now really intensifying. I'm going to enjoy watching the colas form over the next month, month and a 1/2.
