Lights on wake up, bitches (hopefully)

This one is just spitting the roots out

Awesome

I see a reason to leave the wraps on @Bandit420


I just took it off to help airflow since I have no fan

Decaying organic matter when the roots dry out on the sides

There's a moisture gradient they're that they like, a "Goldilocks zone"

She's almost starting to beg me to put her in fruiting conditions

Let it "brick" up more

You’ve been quiet. Too early to harvest anything so I’m guessing it’s now the busy season for you. I hope things are going well.

Yooo

Things went right back to shit more or less but

P3, dryback over night, and check if they are ready for P1 irrigation 2hours after lights on

10ml (1000cm volume cube) 1-2% VWC Pulse shots till saturation, NO RUNOFF.

P2 - E.C/pH MAINTAIN Phase, 10ml shots to maintain proper VWC%.

P3 run-off and over night dryback Phase.

Generative cropsteering cues/patterns.

My run off E.C came out at a insanely high 4.7, plants look great mostly, showing some tip burnt but, negligible

My solution usually is 0.8-1.2 E.C, but recently I bumped towards 1.7, gradually.

I missed some irrigation windows, hence where the E.C spike must be from.

I've not been treating the rockwool like the high-perfomance media it can be, but now that I have more time and Budding, I will.

Correct course and Sail Forward.

Corrected Nutritient ratio profile and levels.

As of yesterday I started reading again about cropsteering and the proper techniques and formulas and whys and how's again.

Dialing my irrigation strategy now that they have grown a bit and are in flower, I will be following P1, P2, P3 Generative cropsteering techniques.

Out of the 6 random seeds in the rockwool cubes, 5 turned out to be females, 1 male.

Odds.

Nutrients Chelation

What is Chelation?

At a basic level, chelation is a chemical process that prevents essential micronutrients (like iron, zinc, copper, and manganese) from locking up in your nutrient reservoir or rockwool.

Without chelation, these metals react with oxygen, carbonates, and phosphates in your water, forming solid, insoluble precipitates (like rust). Once they turn into solids, the plant cannot absorb them, leading to severe nutrient deficiencies.

The Trap: A chelate is an organic molecule (called a ligand) that wraps around a single positively charged metal ion (like $Fe^{2+}$ or $Fe^{3+}$) and binds to it in multiple places.

The Shield: This creates a protective ring or shield around the metal. It blocks outside elements (like phosphorus or high pH hydroxide ions) from attacking and binding to the metal.

The Delivery: The entire chelated complex remains fully water-soluble. When it reaches the roots, the plant breaks the weak chemical bond, pulls the metal inside, and leaves the organic claw behind.

The 3 Different Kinds of Chelates (Spelled Out)

1. EDTA (Ethylenediaminetetraacetic acid)

Chemical Formulas: Free acid is C_{10}H_{16}N_2O_8$. Disodium salt dihydrate is C_{10}H_{14}N_2Na_2O_8 \cdot 2H_2O.
pH Stability Range:1.5 – 6.0

How it works: This is the weakest and most common chelate. It holds a tight grip on metals in acidic environments, but the moment your pH climbs past 6.0, the "claw" opens up and drops the iron.

Best Use: Best used for foliar applications. It loses stability rapidly in rockwool or coco if the root zone pH rises above 6.0, causing iron to drop out of solution.

2. DTPA (Diethylenetriaminepentaacetic acid)

Chemical Formulas:Free acid is C_{14}H_{23}N_3O_{10}. Pentasodium salt solution is C_{14}H_{18}N_3Na_5O_{10}.
pH Stability Range: 1.5 – 7.5

How it works:This chelate has more binding sites than EDTA, giving it a much stronger grip on the metal ion. It does not break down when your root zone experiences normal mid-day pH drifts.


Best Use: The industry standard for hydroponics, rockwool, and coco. It keeps iron completely stable and available to the plant even during typical mid-day pH drifts.

3. EDDHA (Ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid))

Chemical Formula: C_{18}H_{20}N_2O_6$
pH Stability Range: 4.0 – 9.0

How it works:The strongest iron chelate available in agriculture. Its molecular structure completely encapsulates the iron atom, making it practically immune to high pH interference or heavy calcium competition.

Best Use: Used for highly alkaline conditions, soil with heavy calcium carbonate, or hard water setups. It is highly stable but expensive and tints the nutrient solution deep red.



pH Protection:As root zone pH rises, the concentration of hydroxide ions (OH^-) increases.
These ions try to force metals to precipitate out of the water. Stronger chelates (like DTPA) hold onto the metal with a tighter grip, preventing the pH from stripping the nutrient away.

Compatibility:It prevents nutrient lockout in the reservoir, allowing elements like phosphorus and iron to sit in the same tank together without reacting and falling to the bottom as sludge.
