Very top heavy. Growing better than I'd hoped. The longer the exposure, the darker the hue of purple, the newer growth is still green whereas older growth shows colors mixing with natural senescence which shows off all the carotenoids just mixing everything together into a rainbow.
This week will be focused on reducing temperatures during the daytime, keeping good ppfd but switching lights to a veg cycle.
By the end of the week, there will be no red light in this tent.
Then I will replace white light with 3 days of only 285nm, 365nm, 430nm, and 460nm split @ 18 hours (9 for 280nm) and nothing else.
This week she will receive only distilled water with one serving of powdered molasses. Final supper. Water-soluble powder is better.
Start of week we applied humic + fulvic acid
The thing to keep in mind about humic acid is that it is NOT a fertilizer. Fertilizers are nutrients such as nitrogen, potassium, and iron.
Chelation is a type of bonding of organic ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple-bonded) ligand and a single central metal atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents.
Cheluviation is the process in which the metal ions in the upper layer of the soil are combined with organic ligands to form coordination complexes or chelates, moving downwards through eluviation and then depositing.
Metal ions that can participate in chelation include Fe, Al, Mn, Ca, Mg, and trace elements in soil, while the organic ligands combined with these metal ions come mainly from the soil organic matter. Soil organic matter includes relatively stable complex organic compounds (such as lignin, protein, humus, etc.), as well as some simple organic acids and intermediate products of microbial decomposition of organic matter. These organic coordination compounds all contain active groups to varying degrees. Chain organic coordination compounds are complexed with metal ions to generate complexes, and these generated complexes containing multiple coordination atoms in a cyclic structure with metal ions are called chelates. The stability of the chelate is related to the number of atoms in the chelate ring, the stability constant of the chelation reaction, and the concentration of organic chelating agents and metal ions. The chelates produced by fulvic acid and metal ions in soil humus have strong leaching and deposition effects and therefore are an important manifestation of soil cheluviation, which generally results in the formation of gray-white leaching layers and dark brown/red deposited layer.
Humic acid contains no nutrients in this regard but many folks will still see a visual result after an application or two. This isn’t because the humic acid is feeding the plant, but what it is doing is chelating nutrients from the soil that were just sitting there, unused. Applying the humic acid “unlocks'' those nutrients and brings a burst of uptake. This doesn’t happen in every case because some soils just don’t have any nutrients (or much) in them, but many do; it's just those nutrients are locked up and the humic unlocks them, almost immediately.
Also buffers pH which is nice.
Used around a week before the 3 days of blue light. Should have the plant In nutrient turbo mode.
The molasses is going to taste sweet.
Water will be used to transport everything in the last days, the water that is normally exhausted from the stomata at night is where all this extra water is released as a by-product of delivering all the lovely molasses over the plant.
The removal of all red spectrum will initiate a stress response and send the plant into a terpenes production overdrive, normally this tells the plant it's getting late in the season and it must divert all energies to more and stronger smells to attract pollinators from further afield. She has gone this long sensimilla needs fertilized.
Normally this excess smell would be excreted through the stomata. Which we close.
1 week spectral change to 5000k +430-460 Full heavy molasses watering (4-5 Gallons)
Then
RH cranked 20%RH and kept below. Stomatal closure on exposure to 20% rh or below.
3 days of ZERO red - Daytime high not to exceed 67-69 Terpene overdrive preservation.
72 hours of complete darkness. Kept below 67.
3 days of darkness signal to the plant to begin the metabolic process of the decay cycle, self-termination, akin to being blanketed in snow in nature.
Progress right into harvest keeping football intact and boil roots alive to close leaf stomata, dry cure keeping the temps cold to preserve trichomes.
Low and slow.
Wow buddy!! super nice buds
What an amazing grow so far - good job and well done 🤝
Happy Growing & cant wait for your upcoming weeks 🌱
Cheers, Bud Boutique 👩🌾
