ImproGrow Plant Setup & Soil Preparation
Plant Source: All plants were grown from cuttings, purchased at a local grow shop nearby in the city.
Soil Recycling: I am using reclaimed soil that was partially used outdoors last summer. To sterilize it, I processed the soil in the microwave (3L soil with 1L water at 1000W for 35 minutes).
Soil Amendments: After sterilization, the soil was re-inoculated with mycorrhizae and microbes, as well as SST (Sprouted Seed Tea) and ACT (Aerated Compost Tea). Additionally, 28g of rock dust was added per 14L pot.
Transplanting & Initial Care: After transplanting, I watered them with approx. 600ml of a proper nutrient solution. I then let them rest for 6 days to allow the 1L pots to become fully rooted. These have already been placed into the final pots.
Lighting: Greenception LED set to "Veg" at 50% intensity, providing approximately 370–450 PPFD.

ImproGrow Pre-Flower Nutrient Adjustment
Eight days before flipping to the flowering stage (12/12), I applied a top-dressing of Green House Feeding Bio Bloom to balance the specific nutritional needs of each strain:
Imperium X: 20g (total for all plants of this strain)
Candy Store: 20g (total for all plants of this strain)
Apple Fritter: 12g (total for all plants of this strain)
Lilac Cookies: 5g
Foliar Maintenance:
In addition to the nutrient adjustment, I continued the daily light foliar feeding routine, this time including a generous application of Leaf·Coat to provide a protective barrier against pests and environmental stress.

ImproGrow Transition to Flowering
Light Cycle: The photoperiod has been switched to 12.5 hours of light and 11.5 hours of darkness.
Training: A trellis net (SCROG net) has been installed to manage the canopy and support future bud growth.
Hormonal Transition Boost
To further accelerate the transition from the vegetative stage to flowering, I have specifically adjusted the nutrient regimen. I applied a potent dose of AlphaBoost and Aloe Vera to trigger a strong hormonal response. This combination is intended to prime the plants' internal signaling, ensuring a faster and more vigorous shift into flower production.Pest Alert: Despite all preventative measures and the soil sterilization process, a thrips infestation has been detected.
Biological Pest Control Measures
To combat the thrips infestation immediately and biologically, I have purchased a specialized army of beneficial insects:
Nematodes: 1 million beneficial nematodes (specifically Steinernema feltiae) to target thrips larvae in the soil.
Predatory Mittes: A population of predatory mites to patrol the foliage and hunt young thrips.
Lacewing Larvae: 50 Green Lacewing larvae (Chrysoperla carnea), which are highly aggressive generalist predators, to clear the canopy.
I will be deploying these beneficials immediately to regain control of the environment before the flowering phase progresses further.

ImproGrow Beneficials Update:
The beneficial insects have been deployed and are performing well. I am currently maintaining environmental conditions that favor their activity to ensure the thrips are eradicated.
Runoff Analysis:
A small runoff sample (approx. 100ml) showed a Drain EC of 13.4. This indicates a very high salt concentration within the root zone.
Nutrient Pivot: I have not performed a full flush. Instead, I have completely stopped all NPK fertilizers.
Enzymatic Remediation: To manage the high salinity, I am now watering with a diluted solution of hormonal boosters, SST, and ACT. The goal is to use the enzymes and microbes to break down and mobilize the existing salt buildup while providing the necessary signals for the flowering transition.

ImproGrow Emergency Remediation & Pest Control Update
Biological Pest Control
The beneficial insects are performing exceptionally well. Thanks to optimized temperature and humidity levels, the thrips have very limited opportunities to multiply or survive.
Plant Vitality & Structure
The plants remain vibrant and "well-fed" (high nutrient sap), though the stems have become slightly "spongy" due to the over-fertilization and osmotic stress. To counter this and strengthen the cell walls, I have increased the dosage of horsetail extract (silica). Additionally, coconut water is now only applied every second watering.
Root Cause Analysis: Substrate Legacy
I have identified a key factor contributing to the current salinity crisis: the use of recycled soil. In previous cycles, I tended to over-fertilize and used tap water with a baseline EC of 0.65 instead of RO water.
Over time, this caused a significant buildup of mineral salts within the medium. By introducing potent biological additives, enzymes, and Aloe Vera—which are designed to break down and mobilize nutrients—I inadvertently triggered a massive release of these legacy salts all at once. Combined with the current liquid and solid fertilization, this created an overwhelming nutrient load for the plants.
Critical Substrate Analysis & Action
A recent watering with diluted ACT resulted in a runoff with a critical EC exceeding 20.0 and a pH drop to 5.5. To mitigate this immediate threat:
I applied an additional 0.5L of a pH-adjusted mixture (Tap water + RO water).
This was supplemented with Microbes and Enhancer, along with Aloe Vera and Alg-A-Mic, to combat the over-fertilization and break down salt deposits.
The 450ml of runoff (drain) was immediately removed/vacuumed.
Irrigation Strategy Shift
To prevent further salt concentration through evaporation, I am reducing the drybacks.
Substrate moisture is now maintained at 50%, up from the previous 35%.
NPK fertilizers remain discontinued or strictly minimized.
Recovery
Signs of recovery were visible only a few hours after this "mini-flush" and the adjustment of the moisture levels.
Strategic Outlook
Despite the extreme readings, I am not overly concerned at this stage. I view this situation as a form of "extreme crop steering." As long as I can stabilize the substrate and bring the values back into a manageable range within the next 7 days, I am confident the plants will harness this nutrient surge for the upcoming flower production.
