Pink Kush and Sour Bluez

RastaWorld I didn’t take any photos during the first few weeks, mostly because I was worried the plants wouldn’t survive. They were really stressed out by the cold—days barely reached 21 °C, and nights sometimes dropped below 15 °C. For about 2–3 weeks, it seemed like nothing was happening at all. I honestly thought they might die. But thanks to the strong genetics, the plants pulled through — big thanks to Izi and Barney’s Farm seeds!

RastaWorld After a few weeks of almost no growth—about 2–3 weeks—the plants finally recovered from stress and started developing normally. Pink Kush is growing faster: it was transplanted into the auto pod about a week earlier, and Pink Kush also has the AirDome substrate aerator installed. Sour Bluez is a bit behind, but overall looks healthy and strong

RastaWorld The plants are doing well; I am topping the Pink Kush

RastaWorld The plant is thriving, growing strong and healthy. By applying techniques like SCROG and defoliation (removing 5-8 leaves per day), excellent results have been achieved. The transition to the new fertilizer, pH Perfect Connoisseur, has further improved its condition, though previous fertilizers also delivered good results.

RastaWorld So, week 7 has begun. The plants have been switched to a 12/12 light schedule, and the first issues have appeared — the humidity is too high: around 60% during the day and 65% in the evening, sometimes even higher. Without a dehumidifier, it’s currently impossible to lower it. Increasing the exhaust fan’s power didn’t help, so I’ll need to get a dehumidifier. In my opinion, the situation isn’t critical yet, since the flowers haven’t formed, but by the end of the cycle it will be necessary due to the risk of mold. I’ve also started using new nutrients only at the end of the week — Sensi Bloom A and B, along with the Big Bud booster. Overall, the plants are doing fairly well. Both have shown their sex and have stretched a little. I regularly perform defoliation to improve airflow and light penetration to the lower parts of the plants.

RastaWorld The second week of flowering has passed, and the plants have grown significantly—more than I expected. I anticipated some stretch, but not this much. Because of this, I had to move the carbon filter outside and raise the lamp. By the end of the second week, the plants began forming buds and appear healthy. The foliage is growing very vigorously, so I need to trim it regularly. The main issue remains humidity, which rises to around 70% when the lights are off. Buying a dehumidifier seems unavoidable, and I’ll likely need to get one next week. I may also need to add supplemental lighting, as it seems the lower buds aren’t getting enough light. I’m considering placing lights below or to the sides. I’ve seen interesting options, such as the AC Infiniti units — 4 bars with a total power of 45W.

RastaWorld The fourth week of flowering has begun, and the plants are generally doing well, but there are a few concerns: For Pink Kush, the leaves are very dark green, which might indicate a slight nitrogen overdose. I checked the NPK calculator — currently, it’s 125 ml per liter, while the recommended amount is around 85 ml. That’s quite a lot of nitrogen. I’m using Sensi Cal-Mag Xtra at 4%. Next time, I’ll try removing it completely, although that could lead to calcium and magnesium deficiency — I want to see what happens as an experiment. Another option is to adjust the pH Perfect Sensi Bloom base, not at 1:1, but slightly more Part B. If anyone has tried this, please share your experience. For Sour Bluez, I noticed that the distance between the bud sites is very short (seems to be a trait of this strain). Considering the limited space in my grow box, this could cause issues: there’s a risk of mold, and the buds may not fully ripen because light cannot penetrate through the dense foliage.

RastaWorld The fourth week of flowering is over, and the fifth has begun. The biggest update is that I finally bought a dehumidifier. I’ve been wanting an AC Infinity for a while, and I got incredibly lucky—I managed to snag the very last one. The seller said the next shipment won't arrive for two weeks, and I couldn't wait any longer; it was critically needed. Pros and Cons: The dehumidifier is performing great. I managed to drop the humidity to the target 50–55%, down from 70%. One thing I didn't like is the lack of flexible settings right out of the box. Only the fan speed is adjustable, and truly granular control is only available with an AC Infinity controller. Plant Condition: The plants are doing quite well. Regarding nutrients, I’ve decided to stop using extra Cal-Mag. I realized it contains too much nitrogen, which isn't ideal in such high amounts at this stage of flowering. Future Plans: I’m planning to buy the controller eventually and switch completely to the AC Infinity ecosystem to make everything fully automated. My goal is to minimize manual intervention and get the entire grow process running on autopilot.

RastaWorld A lot of work was done for my plants this week. I decided to add an extra fan for better air circulation, since Sour Bluez is a pretty dense plant with tight node spacing, so good airflow is absolutely essential for this strain. Plus, an extra breeze won't hurt the Pink Kush either. I also decided to set up a 40W supplemental light for the lower bud sites, hoping it will eventually make the lower nodes more dense. On top of that, I did a full flush of the runoff trays because I found a couple of fungus gnat larvae. I hope they didn't manage to damage the roots too badly and the problem is sorted out, I'll keep an eye on the situation.

RastaWorld The plants continue to grow actively and stack up density. Next week, I plan to stop using Big Bud and switch to Overdrive. The grow box metrics are stable: temperature and humidity are normal, and the VPD (vapor pressure deficit) stays practically in the ideal range
