Update – Day 19
• The plants are looking excellent and are standing strong “in the juice” with vibrant, lush green leaves.
• Growth has been steady and vigorous over the past week, with no signs of nutrient issues or stress.
• Structure is developing nicely, and the overall impression is very healthy.
⸻
Pest Situation
• Unfortunately, the thrips problem is still present.
• While the plants remain strong and unaffected in terms of growth for now, visible signs of thrips activity continue.
• Beneficial nematodes have been ordered and are expected to arrive on August 20. They should provide a natural and lasting solution to this issue.
⸻
Notes & Outlook
• Until the nematodes arrive, I will continue to monitor the plants closely and manage the pest pressure as best as possible.
• With their strong current condition, the plants seem resilient enough to handle the situation until biological control is introduced.
• Looking forward to seeing a reduction in thrips activity once the nematodes are applied.
⸻
🌱 Day 19 – plants thriving, only the thrips remain as the final obstacle before smooth sailing.
——————————————————-
19.08.
Update – Day 21
• The plants are developing beautifully and continue to grow strong thanks to the Biotabs system and the simple Only-Water method.
• Leaves are a deep, healthy green and the overall structure is compact yet vigorous.
• Growth has been steady, with no signs of nutrient-related issues.
⸻
Pest Situation
• The only downside so far remains the thrips infestation.
• Despite repeated treatments with neem oil, the thrips have not been fully controlled and activity is still visible on the leaves.
• As a next step, I will introduce 5 million beneficial nematodes tomorrow (20.08.) to fight the thrips naturally and directly in the soil.
⸻
Notes & Outlook
• With the nematodes arriving tomorrow, I expect to see gradual improvement in pest control over the coming days.
• Aside from the thrips, the plants are thriving and clearly benefiting from the stable organic feeding system.
• The foundation for a strong vegetative phase is now firmly in place.
⸻
🌱 Day 21 – vigorous growth under Biotabs & Only-Water method, with biological pest control about to take over against thrips.

Update – Day 23
• Yesterday (20.08.) the beneficial nematodes were applied as planned to combat the ongoing thrips problem.
• Application went smoothly, and now it’s time to give them a few days to establish and start working in the soil.
• The plants themselves are looking very strong and vigorous, continuing to benefit from the Biotabs Only-Water method.
⸻
Training
• Today, all ladies were topped above the 5th node.
• The cut was clean and the plants were healthy enough to handle the stress easily.
• This step should encourage bushier growth.
⸻
Notes & Outlook
• Over the next week, I’ll be watching closely to see how the plants recover from topping and how the nematodes affect the thrips population.
• With their current strength and resilience, I expect fast recovery and continued healthy development.
• If the thrips issue comes under control, the grow should progress without further major obstacles.
⸻
🌱 Day 23 – nematodes applied, topping complete, and the ladies are set up perfectly for the next stage of growth.
——————————————————————
26.08.
Update – Day 28 (Week 4)
• Four weeks are now complete, and the plants are slowly beginning their transition into the flowering stage.
• Overall, the garden looks fantastic – healthy leaves, strong stems, and vibrant growth.
⸻
Plant Development
• Guava: Showing much larger internodal spacing, giving them a more stretched structure.
• Apricot: In contrast, these remain very compact and dense, with short internodes and a bushier appearance.
• Both phenotypes look very healthy and vigorous, each with their own growth style.
• The Biotabs nutrient system continues to shine here, keeping everything balanced and stress-free.
⸻
Pest Situation
• The thrips issue is still present, but the situation is clearly improving.
• Since the introduction of nematodes, the pest pressure has started to decrease.
• While a few thrips remain visible, the overall impression is that the problem is finally getting under control.
⸻
Notes & Outlook
• The next days will bring a clearer onset of flowering, with the first pistils already visible.
• I’ll continue to monitor the thrips situation closely, but signs are positive that the biological control is taking effect.
• With strong growth and healthy plants, the stage is set for a promising flowering phase.
⸻
🌱 Day 28 – Week 4 finished: compact Apricots, stretched Guavas, healthy across the board, Biotabs doing great work, and thrips finally losing ground 😎.

MistaOC 04.09.
Update – Day 37
• The grow is progressing well and everything is running according to plan.
• Three of the four plants are thriving with no visible issues, showing healthy structure and steady flowering development.
• One plant, however, is showing slight deficiency symptoms. To counter this, I will begin supplementing with Bio PK this week.
⸻
Pest Situation
• The thrips are unfortunately still present.
• To strengthen biological control, I have today introduced Amblyseius cucumeris and Amblyseius swirskii.
• These predatory mites should help suppress the thrips population more effectively in the coming weeks.
⸻
Notes & Outlook
• The transition into flowering is now fully underway, with buds continuing to form.
• With Bio PK added to the regimen, I expect the slight deficiency to be corrected quickly.
• The new predator mites should establish themselves soon and bring the thrips problem closer to a final solution.
• Overall, the grow remains on track, with strong development and only minor issues being addressed.
⸻
🌱 Day 37 – steady progress, slight deficiency handled with Bio PK, and a new line of defense against thrips with predatory mites.
09.09.
Update – Day 42
• The grow continues much as before – overall, things are moving along steadily.
• Today I applied Bio PK at a dosage of 10 ml per 1 L water to support flowering and correct potential deficiencies.
• Most plants are doing well, but one Guava is struggling. She seems to be either nutrient-blocked or showing stronger deficiency symptoms. For now, it’s a matter of close observation to see where this leads.
⸻
Pest Situation
• The predatory mites (Amblyseius cucumeris & Amblyseius swirskii) are still active and hanging around in the grow.
• However, I have the impression that the thrips population is currently increasing rather than decreasing.
• There is much more movement visible on the leaves compared to before.
• At this point, it’s a waiting game – hopefully, the predators establish themselves and start to turn the situation in the coming weeks.
⸻
Notes & Outlook
• Flowering is progressing as expected, and most plants remain in strong health.
• The coming weeks will be crucial: stabilizing the Guava and getting the thrips population under control.
• Despite the challenges, the overall outlook remains positive as long as the pest issue doesn’t escalate further.
⸻
🌱 Day 42 – Bio PK introduced, one Guava under observation, and thrips still testing patience while predators settle in.

Update – Day 44
• The plants are now well into flowering week 3, and overall development is looking strong.
• Bud formation is coming along nicely, with a structure that already promises solid production later on.
⸻
Feeding
• I am following the Biotabs feeding schedule exactly as recommended.
• Today’s application per plant:
• 1 g Bactrex
• 20 ml Orgatrex (mixed into water and given as a soil drench)
• The plants seem to appreciate the organic support, and bud building is progressing well for this stage.
⸻
Plant Health
• Three of the four plants are in excellent condition, with no visible deficiencies.
• The Guava in the back left continues to struggle – showing signs that could point towards calcium/magnesium (CalMag) shortage or possibly phosphorus deficiency.
• This issue appears isolated, as all other plants are thriving.
⸻
Pest Situation
• The thrips problem remains a major challenge.
• The population seems to be increasing massively, though I keep wondering if some of what I’m seeing could actually be the beneficials (predatory mites) rather than thrips.
• Still, the amount of movement on the leaves is extreme, which weakens the plants overall.
• Despite this external stress, the majority of the plants are pushing through and staying vigorous.
⸻
Notes & Outlook
• Flower development is on point for week 3, which is very encouraging given the pest pressure.
• The next days will show if the predators are settling in and helping reduce the thrips numbers, or if additional measures might be necessary.
⸻
🌱 Day 44 – strong bud development and healthy progress overall, one Guava under pressure, and the thrips situation still demanding patience and close observation.

MistaOC 21.09.Update – Day 54
• We’re now deep into flowering, and unfortunately the thrips problem has not improved.
• On the contrary, the population has completely taken over and has had a strong negative influence on this run.
⸻
Pest Situation
• Despite thorough cleaning before the run and multiple measures during the grow (Neem, Nematodes, Predatory Mites), the thrips kept spreading and finally took control.
• The infestation has weakened the plants noticeably, reducing their potential and overall performance.
• For the next cycle, I will need to take even stricter preventive steps to avoid a repeat of this issue.
⸻
Plant & Bud Development
• Even though the plants were heavily affected, the buds themselves are still relatively solid:
• They are compact, firm, and nicely structured.
• The terpene profile is very appealing, with a rich and delicious aroma.
• Yield will certainly be lower than expected, but there is still a chance for a satisfying end product.
⸻
Notes & Outlook
• This run shows how devastating thrips pressure can be, even under careful preparation.
• Nevertheless, the buds are giving hope for a decent harvest in terms of quality and flavor.
• The plan now is to finish strong, harvest what can be saved, and then prepare carefully for a fresh, hopefully pest-free start.
⸻
🌱 Day 54 – Thrips have dominated the run, but compact buds and great terps keep the outlook positive for harvest quality.

MistaOC 28.09. Day 61
Pest Situation
• Unfortunately, the thrips problem has not improved.
• They are still present in high numbers and continue to affect the plants.
⸻
Harvest
• Today both Guavas were harvested after 61 days.
• The decision was based purely on trichome maturity, not on the thrips infestation.
• Trichomes were at the exact stage of ripeness I personally prefer, making it the perfect harvest time.
• Buds are now drying far away from the grow space to minimize risk of pest transfer.
⸻
Remaining Plants
• The two Apricots are still standing.
• Based on current trichome development, they will likely need about one more week before harvest.
⸻
Notes & Outlook
• Even though thrips remain present, I am satisfied with the Guava harvest timing.
• Buds look dense and healthy, with promising terpenes.
• The focus now is on finishing the Apricots and then preparing for a fresh start without thrips in the next cycle.
⸻
🌱 Day 61 – Guavas harvested at peak trichome ripeness, Apricots still standing, thrips still present.
MistaOC Harvest
• Today, both Apricots were harvested at Day 67 (October 4).
• The buds turned out thick, dense, and beautifully structured – exactly what I was hoping for.
• The aroma is incredibly sweet, almost like fruit jam, with an intense, mouthwatering scent that fills the room.
• Visually, the buds look super frosty and absolutely gorgeous – a great way to end this run.
⸻
Overall Impression
• Despite the constant battle with thrips throughout the grow, these Apricots finished strong and healthy, showing excellent bud development.
• The structure, smell, and stickiness clearly show that the genetics and Biotabs system still performed impressively under pressure.
⸻
Notes & Outlook
• With all plants now harvested, it’s time for a deep clean and reset before starting fresh.
• The next run will definitely benefit from everything learned here – especially regarding pest prevention and environmental control.
• Even with setbacks, this harvest shows that resilience and proper organic feeding can still lead to quality, flavorful buds.
⸻
🌱 Day 67 – Apricots harvested: thick, jam-scented, frosty buds to wrap up the run beautifully.
@Gingobeaz, that sounds really awesome! I'm very curious. I've been recommended these strains multiple times. I'm really looking forward to this grow 👍🏻.
