Blueberry Kush 02, Growers Choice Seeds

ALL ORGANIC! (KIS Organics Water Only Soil with Biochar; started supplementing with Espoma Tomato! And changed calmag from CaMg+ to Organical Magic) WEEK 10 RECAP (short journal comments): The leaves quickly started yellowing this week, so I got worried and started supplementing my watering with Espoma Tomato! Nutes. I know you might think I’m crazy for not using cannabis nutes, but it has everything I need in it, and I think it will work just the same. I also need to use it up before it gets old. The nutes are in the low percentages, and it has lots of beneficial microbes. I also started the use of Recharge and Mammoth P. I’m hoping the yellowing is more due to senescence instead of chlorosis, but I just don’t think KIS Organics Water Only Soil with Biochar can last for a full moderate grow (the owner told me that it is formulated more for 2-3 week veg times, but I would prefer a 6 week veg time so that I can do some LST before flower). I changed my calmag supplement from General Hydroponics CaMg+ to Future Harvest Organical Magic. Since I keep seeing signs of nitrogen toxicity, I wanted to switch to a non-nitrogen based calmag that is still safe for beneficial microbes. I will not be doing a harvest flush. More on this below in my section called “Future Plans”. I think this phenotype is more of an equatorial pheno (commonly known as “sativa”) than my last Blueberry Kush. It is still stretching 4 weeks into flower, and the internodal spacing is larger. Target VPD 1.4kPa. VPD = Vapor Pressure Deficit, the temperature to relative humidity equation that affects plants’ water intake and respiration rates (it had been toeing 1.5 the last two weeks because I’m trying not to get humid enough to introduce mold or mildew). Average light wattage for the week is 572W. ~=~=~=~=~=~=~=~=~=~=~=~ FULL GROW RECAP (the long boring journal comments, unless you’re a nerd like me): ~=~=~=~=~=~=~=~=~=~=~=~ TIMELINE: Pre-Week 1: 1. I put two seeds in peat pods in a seed dome. 2. Light set at low intensities, 142W. Week 1: 3. Seedling “A” popped after 3 days, and “B” popped after 4. 4. Transplanted to 1gal pots to prevent the tap roots from getting too exposed. 5. Target VPD for the seedling cycle was 0.7kPa. 6. Second half of the week light intensity was increased to an average of 238W. Week 2: 7. Halfway through the week changed the Kind LED XL1000 to Automatic Mode. Temps are up. The average daily wattage is now 451W. 8. Halfway through the week adjusted the target VPD to 1.0kPa. Week 3: 9. Removed the “B” seedling from the grow. Now only a one-plant diary. 10. Forgot to get enough soil. 11. Got my new CO2 setup going, but late because of snow. 12. Power outages due to heavy snow outside. 13. Soil farm was closed due to heavy snow. 14. Plant is rootbound and will go one week longer for veg planning. Week 4: 15. Transplanted from a 1gal to a 10gal pot. 16. Put the pot up on a BBQ grill and 2x4s to keep the bottom off the floor. Week 5: 17. Started LST. 18. Changed my mind about doing a SCROG because the Gorilla Grow Tent screen is a piece of crap, and I put in the bottom ring of a tomato cage instead. Week 6: 19. Raised CaMg+ amendment to account for magnesium deficiencies shown by leaf tacoing. Week 7: 20. Flipped to a 13/11 light schedule with a red-only-sunset program to encourage flowering. The average daily wattage is now 572W. 21. Turned heat down to 82degF and increased calmag to reduce leaf curling (high heat is okay with a full amount of CO2. It was even spiking at 84 before this). 22. Target VPD is now 1.4kPa. Week 8: 23. Increased calmag again Week 9: 24: Changed out 20lb (9kg) CO2 tank. Looks like with good usage I will get about 6 weeks per tank. Which means the cost is about $15/6 weeks (not counting setup cost). On the next grow I will probably turn down the output since it doesn’t need to be as high as it is. So I will probably get even more than 6 weeks then. Week 10: 25: See weekly recap at the top. ~=~=~=~=~=~=~=~=~=~=~=~ FUTURE PLANS: I will not be defoliating, unless dead or ground dragger leaves need to be removed. Leaves are both solar panels and batteries for plants, and you actually slow down the plant a tiny bit for each leaf plucked due to shock. If need be, for light or air circulation, I will tuck large leaves. The reason why a plant seems to “boom” after defoliation is just because the plant is trying to quickly regain the leaf power that it just lost. Even the growth of mass in flowers will slow when the plant is trying to expand existing leaves or regrow new ones. Some people deny this, but they should do a side by side clone comparison to prove that defoliation actually increases the yield of a plant. Here are some references so you know I’m not just being random: https://www.cocoforcannabis.com/community/photons_corner/to-defoliate-or-not-to-defoliate/ https://www.mmjdaily.com/article/9181646/does-defoliation-really-improve-a-cannabis-crop/ https://www.icmag.com/ic/showthread.php?t=285930&page=15 I will not be doing a harvest flush. There is no scientific evidence that I can find that says the quality of your bud is hurt by using nutes until finish. There is no other agriculture that uses this practice (vegetables, fruits, etc.), and besides, the plant only takes up what it needs from the roots, so you really aren’t flushing out anything out of the plant. Here is a good read on it: https://support.ilovegrowingmarijuana.com/t/to-flush-or-not-to-flush/6432 ~=~=~=~=~=~=~=~=~=~=~=~ GROW SETUP: GROWING MEDIUM: - KIS Organics: Water Only Soil with Biochar (living soil) CONTAINER: - Vivosun Premium Fabric Pot 10gal (might not fill it all the way) TENT: - Gorilla Grow Tent: Lite Line, 4’x4’ (actually only using 2'x4' space, because I'm sharing the tent with @Mothra) LIGHTING: - Kind LED: K5 XL1000. Every light cycle stage is programmed with a sunrise and sunset mode where the light intensity starts low, increases, peaks, and then gradually dims before shut off. I use lower intensity programs for seedlings, and gradually increase the intensities through veg. I use a Kill-a-Watt meter to measure the actual wattage draw, and will post the wattages of each cycle on this page. HUMIDIFIER (the tent usually runs dry): - Elechomes: UC5501 Ultrasonic Humidifier (has an automatic humidistat control) CO2: - Autopilot APC8200 CO2 Monitor & Controller (has an automatic sensor to regulate CO2 levels, and has a photoeye sensor to keep the CO2 from turning on at night) - DoubleSun Aquarium CO2 Regulator with Solenoid - Two 20lb CO2 tanks (brands always change due to periodic exchanges), only one connected at a time, so that I can exchange the other at my leisure when one runs out. VENTILATION: - AC Infinity: Cloudline T6 (has an automatic sensor control I use to decrease temp and RH) MONITORING: - Pulse One Temp, RH, and VPD monitor with WiFi (I really like this. It really helps me to keep everything dialed in at all times. The graphing feature is a really great addition. VPD (Vapor Pressure Deficit) is the way of the future. - Hydrofarm: CO2 Monitor ~=~=~=~=~=~=~=~=~=~=~=~ STRAIN DECISION: This time I chose to do “Blueberry Kush” from Growers Choice Seeds again because my first plant of this strain was honestly the best weed I have ever had. Blueberry Kush is a Blueberry x OG Kush cross. It had an awesome smell, and the high was calm and relaxing. The aroma was a perfect mix of both the Blueberry and OG Kush parents without one of the flavors suppressing the other. The high doesn’t cause too much couch lock or anxiety - even while still getting you very stoned. Let’s see how well and similar this next phenotype will do. Unfortunately, this strain isn’t listed on this site as an official strain yet, so I have to say “Custom Breeder & Strain”. When I did this strain the first time, the site’s user interface was different and I was able to input the correct breeder. If you’d like to give this Blueberry Kush strain from Growers Choice Seeds a try, you can find it here (I highly recommend it): https://www.growerschoiceseeds.com/shop/cannabis-seeds/feminized/blueberry-kush-feminized-cannabis-seeds/ ~=~=~=~=~=~=~=~=~=~=~=~ THANKS FOR READING!!! I realize having this long of a "Week Comment" is boring, 😴, and deters people from "liking" my journal, but oh well, I'm here to share information, not win likes. 😉 You are awesome if you made it this far down!!! 👍
