Wakíŋyaŋ, I am who I am, the salt of the earth. Thunderbird is an allegory; his conflicts with other forces in nature are then an attempt to allegorize relationships observed in the natural order, such as the changing of the weather. He is essentially an attempt to represent the patterns of activity of a powerful, mysterious force in a way that can be understood simply and easily – sort of the way in which a weather map functions today. Moving from18x60x60 = 64,800 seconds in 18 hours. 64800x860(ppfd) = 55,728,000 umol per daylight. Into Flower 12x60x60 = 43,200 seconds in 12 hours. 43200x1145(ppfd) = 49,464,000 umol per daylight. It's asking a lot of Rubisco regeneration to maintain 50 DLI in the 12 instead of 18. Raised the ambient CO2 to 1200 to 1500 ppm to achieve efficient gas exchange. I don't recommend. Adding sugar to an indoor growing medium is a highly effective way to stimulate microbial activity, which rapidly breaks down the sugars and releases CO2 through cellular respiration. You can safely capture this CO2 to fertilize indoor crops and boost photosynthesis. While this process works, the setup requires precise management to avoid common indoor growing hazards. The plant Carbon to Nitrogen C:N ratio defines the balance between structural carbon (sugars/cellulose) and nitrogen (proteins/enzymes). It acts as a master regulator of plant health, growth, and metabolism. Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is the engine of photosynthesis responsible for fixing atmospheric CO2 into sugars. It is intimately tied to the C:N ratio for three primary reasons. It is the Plant’s Biggest Nitrogen Sink, Drives the Carbon Side, and it is the Nitrogen Control Knob. Understanding this relationship allows you to predict how plants respond to environmental stress or fertilizer. Rubisco acts as the primary storage sink for leaf nitrogen, accounting for up to 30% to 50% of a C3 plant's soluble protein. Deep Green Leaves signal a rich abundance of both chlorophyll and Rubisco proteins. The plant possesses the heavy enzymatic machinery required to handle 1145 PPFD. Pale or yellowing leaves indicate a nitrogen deficiency. The plant is actively breaking down its own Rubisco to salvage nitrogen for newer growth, drastically reducing its light-tolerance threshold. Subtle difference, but understanding is important in order to be able to judge when to dial light intensity up and light intensity down, when to push, and when to back off. An extra dose of magnesium is vital if a plant is going to push through the growing pains of high-intensity lighting. Foliar application of magnesium is an excellent and rapid way to assist with Rubisco regeneration within a plant, so long as it is applied correctly. Spray strictly in the early morning or late evening, mixing your magnesium with a little fulvic acid or chelator, but only when she gets a little limey on top. This, for me, is the experience of growing, akin to "riding the surf" maintaining efficient Rubisco regeneration through visual identification of the shade of green. Surf a razor-thin wave when balancing light intensity, nutrient availability, and transpiration to maximize Rubisco enzyme efficiency. Keeping the Calvin cycle fully charged without tipping into nutrient toxicity, light stress, or the dreaded chlorosis requires paying close attention to the visual cues the plant provides. By monitoring these subtle shifts in color, turgor pressure, and leaf posture, you adjust your environmental controls and surf that exact razor-thin wave. They operate in tandem; nute recycling acts as the vital execution mechanism for autophagy, which defines senescence. Natural senescence is a genetically programmed developmental stage aimed at nutrient recycling, whereas triggered autophagy is a rapid survival response activated by environmental stress. While both processes utilize the vacuole to break down cellular material, their triggers, selectivity, and overall goals are entirely different. Cannabis plant senescence is not separate from nutrient recycling protocols; rather, nutrient recycling is the primary physiological purpose of senescence, and autophagy serves as the core switch mechanism executing both processes. Takes about 24 to 48 hours to notice visible changes once the signals have initiated the autophagic response. Not too late at all. A little bit of fade from senescence 2 weeks from harvest is normal and genetically expected. Send the C:N 32:1 signal 1 week from harvest for the best effect in your organic grow. Understanding what makes leaves fade is not always senescence, but also strongly linked to Rubisco regeneration. That's a whole other subject. Vital to understand the differences if you want a correct diagnosis and to transition from hobby grower to master stoner, differentiating between a true genetic fade and a decline in photosynthetic proteins. Nitrate is nitrate, whether it oxidizes or not is not up for debate. If it's not sunk by the plant you are smoking some if not all of, it's regardless of what your feelings are on the matter. Senescence is highly critical. It is the natural end-of-life stage where the plant redirects energy to ripen flowers. Properly managed, it breaks down harsh chlorophyll, allowing the terpenes (which provide taste and aroma) to peak. Harvesting outside this window leads to an "unripe" or degraded flavor comparable to going without. Now that we've got that out of the way. To initiate the response you seek, you can trigger it multiple ways, when growing synthetically its triggered by nutrient starvation, generally when the entire medium is flushed. This is more to do with N starvation than being entirely empty. Nonetheless. PK boosters are N starvation through maximizing P and K. (Generally only works for synthetic grows) Because you are using organic nutes and you want to maintain the rhizosphere, what you want to do is add carbon in the form of sugars (powdered molasses). It's almost impossible to empty a medium enough when microorganisms are constantly releasing nutrients into the direct EC. Very difficult to initiate starvation responses with ammoniacal nitrogen. Manipulating the C:N ratio is the master key to triggering an autophagic response and resulting nutrient recycling in the last days using organic nutes and without having to flush. Generally not recommended for new growers. So do what you want. But if you don't trigger the plant to dump its nitrates into root zones, you will smoke nitrates as NO3- does not oxidize during the dry and cure no matter what you do or how long you dry or cure. Doesn't matter what anyone "feels" about it, how many grows they had with no fade. That's just how it works. If you are a purist, this is the way to go. "clover steals valuable nutrients." Crop and drop the clover come flipping to flower, its benefit comes from creating an airy and porous rootzone. I don't need to crop and drop once the plant fills the canopy, she blotches out the light, and the clovers die. This is the nitrogen the microorganisms use to convert carbon for respiration throughout the flowering stage.
