Fo' Twenny here with an update on our little Cotton Candy Cane from Emerald Triangle Seeds! 9/16 - Day 12: She is looking healthy and a beautiful shade of green. She's getting tall and growing fast! BAD NEWS: Half of the blue diodes have gone out in the TMLAPY light. This light was actually gifted to me shortly after a friend purchased it from Amazon and realized it was too small for their space. It seemed to be serving it's purpose well for vegging photos and running bumper crops of autoflowers but it failed only four months after the warranty period ended! Weak-Sauce! GOOD NEWS: So, I upgraded the 24"x48" tent to Samsung LM301H boards. I ordered a 320w straight single piece heatsink with 3 boards from Geeklight. I went with the 3k spectrum and switchable UV/IR since all my autoflowers bloom under this light. $306 USD after all is said and done. https://app.alibaba.com/dynamiclink?touchId=1600101815945&type=product&schema=enalibaba%3A%2F%2Fdetail%3Fid%3D1600101815945%26ck%3Dshare_detail&ck=share_detail&shareScene=buyer 9/17 - Day 13: Feed day and installed new lighting. NUTRIENT SOLUTION/FOLIAR SPRAY: ⬇️Mixing Rundown⬇️ Foliar Feed & Nutrient Solution 2 gal tap H2O run through x2 KDF filters Start ppm 630 Start ph 7.8 1 tsp/gal Blue Planet Gold Shield Silica Supplement 1 tsp/gal Fox Farm Gringo Rasta Cal-Mag 8.1 ph .33 tsp gal ph down pH: 6.5 PPM: 730 Serenade 3 tsp/gal (Always adjust pH prior to adding any microbial innocclants) Filled Spray bottle with 32 oz of the 2 gal mixed solution.

so the original clon is having a little issue with the yellow leaves, don't know if it's because it's approaching the end or maybe I started flushing too early I don't really know. and jelly pie is always looking great, for the moment I keep giving them nutrients and I'll start flushing in a small week

March 08 I left the air purifier on by accident again last night so there was a blue light overnight. The buds look good though. I taped the window up so I'm no longer having a humidity issue at night. I alternate between having the light on at 100% and 75% and recently 50% as well. March 10 I just fed them Ph'd water with molasses. Runoff pH 6.2-6.5, ppm 200-600. I'm having trouble getting good shots of the trichromes but I'm starting to see more amber ones. Less than 5%.

Grown outdoors no nutrients just tap water (about 1Gal/day) on the days with no rain... usually around noon when I can see them sag and the weather forecast doesn't predict rain for the rest of the day. I add Terpinator (30mL/Gal) when I water manually. 2020 was an exceptionally warm summer in Quebec. Seeded on May 20th Sprouted on May 23rd Kept in nursery (watered with tap water + B1 vitamin (3ml/L) until Transplanted outside June 16th No Technique applied, she grows as she feels the needs.

4/15 Fighting a soil pH issue. Learned I made some crucial mistakes this entire grow that compounded week after week until a few days ago and I have complete lockout. I was feeding every watering (rookie mistake). I tested runoff and it was at 1800ppm and 3.5 EC, I have done lots of flushing and got soil to an acceptable level of 800ppm and 1.5-1.6 EC. But my soil pH is testing around 4 and will not come up. I have watered with baking soda and it up near 4.5-4.6 now but I have flushed so much over last 3 days I can't stress the plant anymore. Leaves on the bigger plant are rust spotted everywhere and dying off. I will prob lose plant disappointing since it's so far along. I will still yeild something from it but had this not happened this plant would have been great it's super stinky and sticky right now and buds are dense but would have really stacked on and produced had this not happened. Other plant is chugging along its got same soil issues but showing no signs of stress yet. 4/16 Soil pH is still super low on the sick plant and continues to decline, I watered both plants with baking soda water and was able to get the healthier plants soil to 5.8ph. In a last ditch effort to salvage the sick plant, I cut off the fabric pot and transplanted to a planter I had with double the soil capacity. There were no roots stuck to the walls of fabric pot, the base had some but overall I caused very little damage to root system. I watered again with baking soda water and it's now at 4.4ph the fresh soil I put in planter was 6.8 and immediately after watering the new soil tested down to 4. I'm hoping I can get some leaching of buildup from the old soil to the new and get it balanced quickly. I was able to get both plants soil testing around 5.8ph and out of the extreme acidity. There are some spots here and there that are testing a little lower. The healthier plant was showing the slightest spotting all over today, I watered it to about 20% runoff with calmag. Hopefully neither plant get any worse. 4/17 repotting the plant seemed to help tremendously, it really frosted up and seems to have resumed flowering. The other plant seems to be about a 7-10 days behind. 4/20 Bigger plant has really taken on a purple hue, pistils are appx 15-20% turned. Other plant seems to be 7-10 days behind, this is the plant that was over watered in the beginning and was stunted.

And the first week of flower is amongst us, I’m not sure if it’s the fast bud genetics, the living soil, or a mixture of both, but I think the videos say it all, the deep green throughout, day 41 and just look😍. Everything’s been sitting nicely 24/7 Humidity 49~56%, temps 23~26c This week they all received there last top feed, along with a slight bit of defoliation, some massive fan leaves! slightly over watered as you will notice in one of the videos, but I won’t be surprised if they’ve grew another few inches over night.

-27.06.2024 The first week of the vegetative phase begins today. The little plants look quite good. The light is still 100 cm above the plants and is running at 30% (5% more than last week). The values measured with the Photone app are ppfd = 240-270 and DLi = 15.5 - 17.5. The temperature is 22.9 degrees and the humidity is 65%. -28.06.2024 The plants were watered properly for the first time today. About 500ml per plant. A little bit of mycorrhiza was added to the water.. -29.06.2024 Visual inspection, everything looks good. I put sticks in the soil as a precaution to give the plants some support. -30.06.2024 Today the soil felt quite dry so the plants got about 200ml of water (per plant). I also increased the light intensity slightly. Measured values with the Photone app: Ppfd = 300-320 DLi = 22.5-23.6 . -01.07.2024 Just a visual check, everything looks good so far -02.07.2024 visual check, the soil was dry again so each plant got 200ml of water. The distance to the lamp was reduced by 20cm and it now hangs 80cm above the plants. Measured values with the Photone app: PPfd = 360-370 DLi = 25.8-27 -03.07.2024 The last day of the first week in the vegetative phase. The soil was dry so each plant got 200ml of water.
