BC_Green After exclusively growing photoperiods, I am excited to try Auto Orange Bud by Dutch Passion. This seed was a freebie, and I am interested to see what she does! I had this seed in the fridge for a few months, so last Friday I took it out and let it warm up in a cabinet. Sunday, I germinated it by soaking it in water mixed with 40 ppm soy hydrolysate for 10 hours, then transferring it to a paper towel soaked in water with 40 ppm soy hydrolysate. I noticed her taproot popped out Tuesday morning, and I planted her directly into her first/final container, a 10-gallon fabric pot. The bottom ¾ of the fabric pot is filled with ⅓ perlite, ⅓ peat moss, and ⅓ meadow soil (from a friend’s house) with living roots and plant matter included. The top ¼ of the container is Pro-Mix BX. I watered the media with a ¼ strength dose of my own 5-1-5 fertilizer–here is what I used: Soy hydrolysate (12-0-0) - 0.61 grams Liquid Fertilizer (4-10-3) - 0.65 grams Potassium Nitrate (13.5-0-46.2) - 0.39 grams One gallon of water I then placed a Tupperware over it as a humidity dome until she broke the surface yesterday. I am letting her get a little morning sun, but otherwise, I will keep her in the shade for the first few days and slowly introduce her to more direct light.

BC_Green We had five days of rain last week (and more this week). Initially, I had positioned her below the gutters to keep her from getting too wet, but after day two, I moved her into my shed with a grow light and fan to prevent her from damping off. The good news is that she is still alive, and we have had a little dry weather (so I am moving her outside during the day to speed up drying out the media), but moving her back inside at night. The grow light is set to a 20-hour light and 4-hour dark schedule (with a wifi socket) per the recommendations of Dutch Passion–and I am following the recommended light intensity schedule from Photone (free app to measure light intensity). https://growlightmeter.com/autoflowering-cannabis-lighting/ Sadly, I couldn't deliver any water-soluble nutrients with all the rain and the media already so wet, but she already has a few spots on her leaves, so I didn't want to add any more moisture to the media.

BC_Green Despite the miserable rainy start for this little lady, she toughed it out and now everything is going along pretty smoothly now. She has continued to stay in the shed with a grow light and fan as the rain continued this past week. We have a few days now with some drier weather, so I am getting her outside for part of each day, but as I now have her on a 20/4 light schedule, I am going to stick with that until she finishes to avoid any issues. I was able to water her once this week with a half strength dose of my fertilizer blend. ½ strength (per gallon): Soy hydrolysate (12-0-0) - 1.2 grams Liquid Fertilizer (4-10-3) - 1.3 grams Potassium Nitrate (13.5-0-46.2) - 0.78 grams I have to deliver micro nutrients separately as they tend to precipitate when combined with the liquid fertilizer, so I will be doing that as soon as the soil dries out more.

BC_Green Everything is going well for my little auto. She’s picking up size and looks healthy. I did notice a moth in my shed (that I wasn’t able to remove or eliminate), so I went ahead and sprayed the plant down with neem oil to hopefully prevent her from laying any eggs on it (and the young hatching and eating the leaves). Otherwise, she’s doing great.

BC_Green No issues to report, she is growing healthy and starting to pick up some size! She is female for sure, but no signs of flowering quite yet. I have been increasing the light intensity each week, following Photone’s recommendations (and using their app to check the light intensity): https://growlightmeter.com/autoflowering-cannabis-lighting/ Since I am using a light schedule of 20 hours on, I used this calculator to figure out the PPFD I need to reach 45 DLI (which is 625): https://www.waveformlighting.com/horticulture/daily-light-integral-dli-calculator I watered once this week using my fertilizer blend (per gallon): - Soy hydrolysate (12-0-0) - 2.43 grams (160 ppm nitrogen (77 ppm from soy hydrolysate + 27 ppm from liquid fertilizer + 56 ppm from potassium nitrate)) - Liquid Fertilizer (4-10-3) - 2.6 grams (30 ppm phosphorus - measured with a cup on a scale) - Potassium Nitrate (13.5-0-46.2) - 1.56 grams (175 ppm potassium (158 ppm from potassium nitrate + 17 ppm from liquid fertilizer)) * I don't enter this under the nutrient section as tsp/gal is too inaccurate for my preference, and I use a scale to measure everything Looking forward to flowering!

BC_Green She really started to take off this past week and is looking really healthy! As she grows, I am raising the light to keep a consistent DLI. When I checked her out yesterday I saw evidence of something sucking on her leaves, then found a tiny woolly aphid. I had actually seen some fuzz on my OG Fun clone last week and picked off (squeezing it as I did so, assuming it was eggs), but that may have also been a woolly aphid. I sprayed some Captain Jack’s Dead Bug Brew on all plants in the shed and will keep a close eye on them. There are no real signs of flowering yet, so I decided to try a fimming cut to see if I can get the stem to split into four. I may have been a touch low, so it may only be a topping cut, but we’ll see. I also performed a light defoliation of leaves that were clearly no longer receiving light due to the expanding canopy. I watered once this week using my fertilizer blend (per gallon): - Soy hydrolysate (12-0-0) - 2.43 grams (160 ppm nitrogen (77 ppm from soy hydrolysate + 27 ppm from liquid fertilizer + 56 ppm from potassium nitrate)) - Liquid Fertilizer (4-10-3) - 2.6 grams (30 ppm phosphorus - measured with a cup on a scale) - Potassium Nitrate (13.5-0-46.2) - 1.56 grams (175 ppm potassium (158 ppm from potassium nitrate + 17 ppm from liquid fertilizer)) Otherwise, I will head out of town this week (so no updates next weekend), but I will water her well with nutrients before I go and ensure there’s no new leaf damage (if there is, I will spray again).

BC_Green After more than a week of being gone, I returned to a flowering plant! She was certainly dried out a bit, and had grown within 4” of the light (increasing the intensity to 1,315 PPFD, instead of the target 625), but showed little sign of stress. Something is munching on her leaves, so I sprayed her with some neem oil, but the damage is certainly insignificant compared to the explosive new plant growth. The attempt at FIMMing ultimately yielded topping cut results, but she’s growing beautifully bushy and I’m excited to see the results!

BC_Green My little auto orange bud picked up another 6” this past week and is looking great! The neem oil spray has ceased the leaf damage, which is great, because I prefer to stop spraying during flowering when possible. She is definitely growing very bushy, and many of the lower leaves are not receiving much light (I did add two large pieces of cardboard covered in aluminum foil to distribute light better). I removed the leaves tucked in the center of the plant, as well as most of the secondary shoots off main branches (that look to be forming underdeveloped buds). Hopefully, this will focus the plant's growth on a couple of nicer colas. I did notice a woolly aphid during defoliation (and disposed of it), so I will need to continue to keep an eye on her. Additionally, with the heat and increased size she is definitely sucking up a lot more water. As she is now officially flowering, I have switched her to a decreased level of potassium (from 175 ppm to 60 ppm) based on this Israeli summary article: https://israelagri.com/advances-in-science-based-fertilization-technologies-for-medical-cannabis/#:~:text=optimal%20nitrogen%20level%20at%20the,concentration%20of%20cannabinoids%20and%20terpenoids Flowering mix: N 160 ppm - P 30 ppm - K 60 ppm Ingredients: 1.86 g per gal 12-0-0 soy hydrolysate 1.3 g per gal 4-10-3 liquid fertilizer 1.06 g per gal 13.5-0-46.2 potassium nitrate Otherwise, I'm getting excited to see what happens! *** Update 7/6/25 **** I was reviewing my calculations this week and figured out that I made a mistake on potassium nitrate, and I wrote per gallon above, but it was actually for a half gallon. The above weights actually delivered 221 ppm Nitrogen, 30 ppm Phosphorus, and 231 ppm Potassium (and a few brown/yellow tips on lower leaves). The correct fertilizer blend for 160 ppm Nitrogen, 30 ppm Phosphorus, and 60 ppm Potassium for a 1/2 gallon is: 1.86 g soy hydrolysate 1.3 g 4-10-3 liquid fertilizer 0.21 g potassium nitrate

BC_Green Her stretch seems to be finished and flowers are now progressing nicely! I did a touch more defoliation this week to clean out any final leaves or buds that looked under utilized/developed, but overall she looks great. I also used LST on three shoots that stood taller than the rest of the canopy to keep the height more uniform and I noticed no negative impacts. I did make a mistake on my fertilizer blend last week, and updated the diary accordingly. It did cause yellow/brown leaf tips on 3 lower leaves. That symptom caused me to review all of my calculations before fertilizing yesterday, and the corrected flowering blend (160 ppm Nitrogen, 30 ppm Phosphorus, 60 ppm Potassium) is: Per ½ gal 1.86 g soy hydrolysate 1.3 g 4-10-3 liquid fertilizer 0.21 g potassium nitrate

BC_Green Just one week from officially switching to the flowering fertilizer blend (160 ppm nitrogen, 30 ppm phosphorus, and 60 ppm potassium) and already the potassium deficiency is showing on the leaves. This blend I designed is based on Israeli control studies that revealed that cannabinoid potency is enhanced with phosphorus and potassium starvation, while yield is diminished. https://israelagri.com/advances-in-science-based-fertilization-technologies-for-medical-cannabis/#:~:text=optimal%20nitrogen%20level%20at%20the,concentration%20of%20cannabinoids%20and%20terpenoids My goal is potency, so I am willing to sacrifice quantity for quality. Experimenting with this autoflower is the perfect opportunity to determine if this method is effective and whether/how I might apply this same strategy to my outdoor and future grows. Thus far, the buds are starting to look nice and frosty. We’ll see what I get in the end...

BC_Green She’s entering week 5 of flowering and looking great. Signs of potassium deficiency (from the flowering fertilizer blend I am using) are continuing to develop (hopefully leading to higher cannabinoid concentrations). I removed the garden wire and bamboo stakes I was using for the bit of LST. The canopy of the plant is a nice canyon, allowing for a fairly even light distribution across it. We're in the home stretch, though, looking forward to seeing how she finishes!

BC_Green The buds are picking up a bit of size and smelling wonderful! The lower potassium fertilizer blend I am using continues to cause a bit of damage to the leaves, but slower than I expected. I’m looking forward to harvest! I am switching over to using Mono Potassium Phosphate for my source of potassium this week, so my new flowering fertilizer blend is: Mono Potassium Phosphate - 0.5 grams per gallon Potassium Nitrate - 0.22 grams per gallon Soy Hydrolysate - 4.8 grams per gallon I will update the nutrient section once I get a guestimate for tsp/gal.
