P2 & P3 - ILGM Blue Dream 4x4 tent grow

Wednesday, December 6, 2023 (Day 99, 49 days into flower) - I have probably about 10-15 gallons of my current nutrient solution that I want to use up over the next day or two so I've increased fertigation time from 40 to 60 seconds. I then plan to switch to the Finish nutrients as per Jack's Nutrients nutrient schedule. When it's time to mix that, instead of 15-5-20 it will be 7-15-30 (~130 grams per 24 gallons but I may need twice that) and Epsom salt (~24 grams per 24 gallons but I may need twice that); EC goal remains 2.1 (plus background tap water EC.) The trichomes to me appear 10-20% cloudy but otherwise clear. I'm estimating 1-2 weeks until harvest. (Thank you Grow Question answerers for the feedback/guidance!) I dumped the last of the nutrient solution, cleaned the reservoirs, and mixed up the Finish solution as described above: 1. 24 gallons tap water (EC 0.396) 2. 60 mL Armor Si (then wait at least an hour) <-- used up the last of Armor Si; I don't plan to buy more for this grow. 3. 130 grams Jack's Nutrients 7-15-30 and 24 grams Epsom salt (I ended up using 260 grams and 48 grams to get close enough to the target EC...) [I didn't use Diamond Nectar because I haven't bought more and I consider it optional, particularly so close to harvest.] 4. 3/4 teaspoon Yucca ..... Check and adjust EC to goal of 2.1 + tap = 2.496. Actual result: _2.550_ ..... Adjust pH to 5.8-6.2. Actual result: _5.8_ 5. 60 mL H2O2 I adjusted the fertigation timing from 60 seconds back to 40 seconds. ----- Thursday, December 7, 2023 (Day 100, 50 days into flower) - Today will be the first full day of fertigation with the Finish formulation from Jack's Nutrients. I'd broken a couple of small branches that had bud a couple weeks ago and it's been curing in a Grove bag. I smoked some today and even though it was not fully developed or dried/cured ideally, the smoke was smooth and the effects feel good. I'm excited for how the actual harvest ends up! ----- Friday, December 8, 2023 (Day 101, 51 days into flower) - I'd say trichomes are 50-75% cloudy, the rest clear. ----- Saturday, December 9, 2023 (Day 102, 52 days into flower) - I need to get a trim tray and maybe micron mesh bags to extract hash from the trim via dry ice. ----- Sunday, December 10, 2023 (Day 103, 53 days into flower) - Yesterday, I ordered a trim tray that has a micron screen. Trichomes today look to be ~90% cloudy; I don't see any amber. I cut three small lower branches and hung up to dry. They won't be protected from reflected light (at least they're above the LED lights) and the humidity is ~50% and temp is ~70%, so not ideal dry conditions. I tried using the moisture meter and used Wood category C, which includes oak. (That's what the Grove customer service person said when I asked for guidance. They also said use the setting for the softest wood, which I wouldn't expect to be oak....) The meter read ~40% eyeball average, as the results varied based on where I put the prongs of the meter. I haven't trimmed even the big fan leaves in hopes that will slow the dry timeline. ----- Monday, December 11, 2023 (Day 104, 54 days into flower) - I'm reading about moisture meters today so hopefully I'll better judge which setting to use when testing harvested cannabis. When I put the pins in the stem and bud and do nothing other than switch the wood type, A is lowest at ~20% then it increases into the highest, D, at about 30%. From what I could find out, the softer woods show a higher reading compared to the harder woods, so if I should use the softest wood setting, I'd use D. I'll also pay attention to stem snapping vs bending, which is the more traditional way of figuring out when to start curing. Since my lowest temperature (presumably, with lights off, has been ~68 F, I'll probably need to increase humidity above 60% RH to try to slow down drying. Humidity has been ~45-55% lately. Looking at the trichomes today, I still don't see any for-sure amber and most still seem cloudy, although now more seem clear than I saw the last couple of days. Maybe more trichomes being made? Almost out of this batch of nutrient solution so will be making a new batch tomorrow morning or so; that might be the penultimate and possibly the final batch before harvest! ----- Tuesday, December 12, 2023 (Day 105, 55 days into flower) - Still no amber trichomes. Some of the leaves are showing yellowing which may be just because the plant is toward the end of its life cycle; of course, it may also be a problem but I'm so close to harvest I'm not going to change anything. Made a new batch of nutrient solution: 1. 24 gallons tap water (EC 0.382) [All out of Armor Si so none in this batch.] 3. 130 grams Jack's Nutrients 7-15-30 and 24 grams Epsom salt (I ended up using 261 grams and 54 grams to get close enough to the target EC...) [All out of Diamond Nectar so none in this batch.] 4. 3/4 teaspoon Yucca ..... Check and adjust EC to goal of 2.1 + tap = 2.482. Actual result: _2.476_ ..... Adjust pH to 5.8-6.2. Actual result: _5.9_ 5. 60 mL H2O2 ----- END OF 15TH WEEK FROM SEED
