Stoney_Stark UNABLE TO SAVE A GERMINATION PAGE, THIS FIRST WEEK WILL ACT AS BOTH MY GERMINATION AND WEEK 1 PAGE
October 18th, 2025: Germination / Setup (Sponsored Grow by izi.farm)
This grow is an organic sponsored run by izi.farm through the Growroom420 Discord community. I’m growing four Fast Diesel photoperiod feminized plants.
For the medium, I’m using 100% Fox Farm Happy Frog soil. The soil was amended with 1 tablespoon of Gaia Green 4-4-4 per gallon of medium for balanced nutrients, along with ¼ teaspoon per gallon of Real Growers Recharge and Xtreme Gardening Mykos to boost microbial activity and root development.
Each seed was planted directly into the soil in a 1-gallon pot, placed about ½ inch deep, and the soil was lightly moistened. I then covered each pot with a humidity dome to maintain optimal moisture and humidity during germination.
All four pots are set up in a 32" x 32" grow tent under a Vivosun 200W LED. This small tent setup is temporary — my 4x4 tent is currently occupied, but should be available within the next week or two. Once it’s free, these plants will be moved under the Mammoth Nova Sun Series 950W spectrum-tuning light for continued vegetative growth.
OCTOBER 21st, 2025: Today marks the first visible signs of growth in Pheno 3 and Pheno 4. Both have begun to break the surface, showing healthy early development. To maintain ideal humidity and promote strong early root growth, I plan to keep the humidity domes on for another day with these two phenos.
Pheno 1 and Pheno 2 have not yet shown visible growth above the soil, but based on the timing and consistency of the medium, I expect them to emerge within the next day or two.
So far, moisture levels remain stable, and the environment inside the 32"x32" tent continues to support healthy germination conditions under the Vivosun 200W LED.
October 22nd, 2025: All four seedlings have successfully emerged and are showing strong early growth. To maintain proper moisture levels, I lightly misted the top layer of soil using a sprayer.
I prepared a ¼ gallon feeding solution containing:
0.25 mL Silicium
0.25 mL CalMag
1.5 mL Pure Zym
1.5 mL Photosynthesis Plus
¼ tsp Real Growers Recharge
I didn’t apply the entire ¼ gallon—just enough to moisten the surface and lightly water around the edges of each pot. This approach helps initiate microbial activity and begin breaking down the organic material in the soil without risking overwatering, which can be harmful to young seedlings.
I decided to add CalMag to my feed this time, which isn’t something I normally do. The reason is that I’ve been noticing recurring magnesium deficiencies when using my tap water.
Last night I started thinking — why am I still seeing magnesium deficiencies when I’m already adding Epsom salt to my dechlorinated water? My tap water is pretty bad, testing around 450+ ppm with a pH of 8.1, and I get heavy calcium deposits on all my faucets. So, I looked it up and found that excess calcium can lock out magnesium uptake in plants. That definitely explains what I’ve been seeing.
With that in mind, I’m thinking of switching to RO water for this run. It should give me a cleaner starting point and help prevent nutrient lockout from the excess minerals in my tap.
If anyone has experience with this or any insights, I’d love to hear your thoughts.
October 23rd 2025: Today the plants received their first full watering. I used the remaining ¼ gallon of nutrient solution prepared yesterday to moisten the top layer of soil. The specific nutrient amounts are listed in the previous entry.
Moving forward, I’ll be transitioning to reverse osmosis (RO) water for this grow to avoid issues caused by the high calcium content in my tap water. To ensure the plants still receive sufficient calcium and magnesium, I’ll be supplementing the RO water with Scientetics MagCal.
October 25th, 2025: THE START OF THE SECOND WEEK- The plants are looking vibrant, lush, and uniform across the canopy. Growth has been steady and consistent, with each plant showing similar structure and leaf development—an encouraging sign of stable genetics and balanced environmental conditions. The color across all leaves is a rich, healthy green, indicating proper nutrient uptake and good overall plant health.
Today, I performed a light watering using ¼ gallon of reverse osmosis (RO) water split between the 4. To the water, I added:
•0.25 ml of Silicium – to strengthen cell walls, improve stem rigidity, and increase stress resistance.
•0.5 ml of CalMag – to supplement calcium and magnesium, ensuring strong leaf structure and preventing early deficiencies, especially important when using RO water.
This watering was mainly aimed at maintaining consistent moisture levels and providing a small boost of essential micronutrients without overwhelming the root zone. The plants responded well, showing no signs of stress or overwatering.
Environmental conditions remain stable, and leaf posture continues to indicate strong turgor pressure and optimal transpiration rates. I’ll continue monitoring for any subtle changes in leaf color or structure as they grow into their next feeding.
Overall, the grow is progressing beautifully, with even growth and no visible deficiencies at this stage.

Stoney_Stark All four seedlings are doing great as we wrap up week two since planting. Growth is steady and healthy — the first set of five-fingered leaves is now starting to show, which means they’re just about ready to enter the vegetative stage. No signs of stress or deficiencies so far.
Feedings this week:
10/26: Mixed up ¼ gallon RO water with
0.25ml Silicium
0.5ml CalMag
1.25ml Ruby Fulvic
1.25ml Carb-o-Naria
pH 6.1, 545ppm, divided evenly between the 4 plants.
10/31: Gave another ¼ gallon RO water with
0.25ml Silicium
0.5ml CalMag
1.25ml Ruby Fulvic
⅛ tsp Recharge
pH 6.1. divided evenly between the 4 plants.
The plants are showing nice color and early vigor. Growth between the phenos is fairly even, and I’m keeping humidity high to encourage strong root expansion. Next week I’ll slowly start increasing feed strength as they move into veg and begin filling out more.

Stoney_Stark This week marks an exciting move for the Fast Diesel girls — they’ve officially been relocated into the 4x4 tent and are now growing under the Mammoth Nova Sun 950W spectrum-tuning LED. The light is currently dialed in at 50% total output, delivering about 300 µmol/m²/s (PPFD) at the canopy level, which provides a gentle yet efficient intensity for early-stage growth.
I’ve got the spectrum tuned to 80% cool white and 20% warm red, with IR turned off for now. This mix favors strong vegetative growth and short internodal spacing, while introducing just enough red to begin promoting healthy root and stem development. The Mammoth’s spectral control really allows for fine-tuning — it runs cool, distributes light evenly corner to corner, and the PAR readings stay consistent across the entire footprint.
💧 Feeding & Nutrients
They only received one watering this week, and I kept it light:
¼ gal RO water, split among the plants
0.25 ml Silicium (silica supplement to strengthen cell walls and enhance stress resistance)
0.5 ml CalMag (to provide balanced calcium and magnesium, especially important when using RO water)
1.25 ml Ruby Fulvic (from New Millennium — a high-quality fulvic acid for improved nutrient uptake and root vitality)
0.25 ml Rhyzium (beneficial root stimulator that promotes root mass and microbial activity)
The mix was pHed to 6.1 and came out to 550 ppm, a nice mild feed to maintain steady growth without overloading the young root system.
The plants are looking happy and well-adjusted to their new environment. The canopy is even, leaf posture is great, and they’re showing strong vigor under the new light setup. I’ll gradually increase PPFD over the next week as they acclimate.
