ETHOS & GHSC - (Diary #9)

Welcome to another ridiculously detailed grow by Louder! If you've followed any of my diaries in the last 2 years, you'll see some familiar faces. King's Tart was so good I had to grow it again, hopefully mistake free. 10th Planet I've ran twice and Banana Daddy once. 10P has been very consistent in quality no matter what I've done. BD was slow growing and low yielding last time so I'm really hoping to get a big improvement here. We've got our cheat sheets and looking to smash previous yields. As always, there will be an absolutely shocking amount of notes with lots of updates! So let's get into it!!

Without sets of true leaves, the plants aren't IN the vegetation stage yet. Once there's one set of true leaves, I'll start the fertigation schedule. When there's 5-7 sets of true leaves, the seedling period ends and the plant enters vegetation WEEK 1. TARGETS: • 22-25C ✅ • 65-75% ❌ (High fluctuations 80+) • 0.42-0.72 VPD 🆗 • 1.0 EC / 6.0 pH ❌ (0.9) • Let pots dry out at least 75% before the first full watering ✅ __________ Sept 16 🌡️- 25.3c ✅ ❄️ - 22.6c ✅ 🌧️ - 79% ⬇️ ☁️ - 59% 🆗 📈 - 0.76 ✅ 📉 - 0.6 ✅ 📊 - 0.71 ✅ The single serrated leaves are getting bigger every day. Vibrant green colour, straight and sturdy stems on all. Humidity is a bit on the high side at night but it's better than being too dry at this stage. The seedlings are mostly taking water in through the leaves so we don't want to drown the fragile tap root with water. OXYGEN is more important to get roots growing quickly. __________ Sept 17 🌡️- 25.5c ✅ ❄️ - 21.8c ⬆️ 🌧️ - 72% ⬇️ ☁️ - 61% ✅ 📈 - 0.76 ✅ 📉 - 0.55 ✅ 📊 - 0.7 ✅ __________ Sept 18 🌡️- 25.5c ✅ ❄️ - 21.1c ⬆️ 🌧️ - 74% ⬇️ ☁️ - 59% 🆗 📈 - 0.62 ✅ 📉 - 0.58 ✅ 📊 - 0.6 ✅ _________________ Sept 19 Mix: 1ml CaMg, 1ml A, 1ml B, 1ml PB Tea : 2L water = 0.9 EC 💧: 250ml BD4 IN: 0.9 EC/5.9 pH (20c) OUT: 0.8 EC/5.8 pH (22c) BD5 IN: 0.9 EC/ 5.9 pH (20c) OUT: 0.8 EC/5.9 pH (22c) KT4 IN: 0.9 EC/5.9 pH (20c) OUT: 0.8 EC/5.8 pH (22c) KT5 IN: 0.9 EC/5.9 pH (20c) OUT: 0.8 EC/5.8 pH (22c) 10P6 IN: 0.9 EC/5.9 pH (20c) OUT: 0.8 EC/5.7 pH (22c) 10P7 IN: 0.9 EC/5.9 pH (20c) OUT: 0.8 EC/5.7 pH (22c) 🌡️- 26.1c 🆗 ❄️ - 22.4c ✅ 🌧️ - 82% ⬇️ ☁️ - 59% 🆗 📈 - 0.8 ✅ 📉 - 0.38 ⬆️ 📊 - 0.65 ✅ 2nd set of leaves are showing! The pots were light so I watered them all. Wanted some runoff just to see where the substrate is at. They haven't been fully saturated since the coco was buffered. I'd like to see the pH a bit higher but that's super easy to correct this early. I usually keep the fertilizing to a bare minimum at this stage but this time we're trying the @FrontRowAG_BrianG method of EC stacking right from the jump. If I have the logic correct, this involves starting out at a relatively high (but safe) EC and allowing the plant to get accustomed to high doses of nutrients earlier on in veg. The goal is to reach 1.8 EC by week 4. Provided the VPD is in check, this allows you to push the EC while it's in bloom to produce bigger yields. Go look at his diaries if you're skeptical. Going forward, I won't be getting much in terms of runoff (if any) and using scheduled flushes at the end of VEG, end of week 2 FLR and end of week 5 FLR. We're flushing for 2 weeks at the end (week 8/9). ___________ Sept 20 🌡️- 25.9c ✅ ❄️ - 22.5c ✅ 🌧️ - 87% ⬇️ ☁️ - 58%⬆️ 📈 - 1.15 ❌⬇️ 📉 - 0.39 ❌⬆️ 📊 - 0.74 ⬇️ • Humidity too high during lights off • Humidity too low during lights on It's been rough getting the VPD right lately. If I take the dome off, humidity plummets to 50%. If I leave it on, it skyrockets to near 90%. That being said, the seedlings look great. The pots are maybe halfway dry from the first fertilizing event so I'll give it another day or so before watering again. Only issue is 10P6 has a bit of a yellow leaf tip. ____________ Sept 21 🌡️- 26.1 ✅ ❄️ - 23.2 ✅ 🌧️ - 71% ✅ ☁️ - 58% 🆗 📈 - 0.99 ❌⬇️ 📉 - 0.72 ⬇️ 📊 - 0.88 ❌⬇️ • Dome off all day • Fan on aiming up (light rocking for seedlings) • Sprayed a mold killer on the seedlings (thought I saw WPM) • Looks like it was just diatomaceous earth I sprayed • Got a slumpy seedling (10P6), propped up _________ Sept 22 🌡️- 25.8c ✅ ❄️ - 22.8c✅ 🌧️ - 71% ✅ ☁️ - 62% ✅ 📈 - 0.81 ⬇️ 📉 - 0.7 ⬇️ 📊 - 0.79 ⬇️ _______________________________ SEEDLING WEEK 2 (Sept 23-29) TARGETS: • 22-25C • 65-75% • 0.42-0.72 VPD • 1.0 EC / 6.0 pH ✅ __________ Sept 23 🌡️- 26.1c ✅ ❄️ - 23.2c ✅ 🌧️ - 78% ✅ ☁️ - 54% ⬆️ 📈 - 0.85 ⬇️ 📉 - 0.55 ✅ 📊 - 0.76 🆗 • Changed light schedule to 18/6 • 3rd set of leaves showing _________________ Sept 24 (250ml) Mix: 1ml CaMg, 1ml A, 1ml B, 1ml PB Tea : 2L water = 1.0 EC BD4 IN: 1.0 EC/6.0 pH (22c) OUT: 1.1 EC/5.9 pH (23c) BD5 IN: 1.0 EC/6.0 pH (22c) OUT: 1.0 EC/6.0 pH (23c) KT4 IN: 1.0 EC/6.0 pH (22c) OUT: 1.0 EC/5.9 pH (22c) KT5 IN: 1.0 EC/6.0 pH (22c) OUT: 1.0 EC/5.9 pH (22c) 10P6 IN: 1.0 EC/6.0 pH (22c) OUT: 1.1 EC/5.9 pH (23c) 10P7 IN: 1.0 EC/6.0 pH (22c) OUT: 1.1 EC/5.8 pH (22c) 🌡️- 26.4c 🆗 ❄️ - 21.5c ⬆️ 🌧️ - 84% ❌⬇️ ☁️ - 59% 🆗 📈 - 0.85 ⬇️ 📉 - 0.4 ✅ 📊 - 0.62 🆗 Last watering was 5 days ago and the pots were super light.

Still having an issue with low humidity...I'd like to keep a fan running to get the stems strengthened up but that erases the humidity I need. The second watering came with the pots about 50% dry. All are producing similar runoff values for now. 4 of 6 seedlings are looking pretty good with BD5 and KT4 looking the best. 10ths aren't doing as well. One needs to propped up or it will slump over sideways. They both have some yellowing crispy leaf edges as well. so maybe they can't handle what the others can. I'm a bit paranoid about spider mites and wpm this time of year, and at this early stage when they're so vulnerable. Just ordered an LED magnifier to confirm there isn't anything fucked going on. ___________ Sept 28 10ths are looking super weird. Slow and mutated growth, weak stems...nothing like I've seen out of the (now empty) 10 pack. The others have been given the exact same treatment and look totally fine. Don't think I'll waste much more time on them. There's something very special coming anyway 😉 ____________ Sept 29 🌡️- 26.4c ✅ ❄️ - 23.3c ✅ 🌧️ - 74% ✅ ☁️ - 52% ⬆️ 📈 - 0.76 ✅ 📉 - 0.67 ✅ 📊 - 0.7 ✅ There's at least 3 sets of true leaves now so I'm going to end the seedling stage and begin the vegetation stage. Getting some better VPD numbers last few days and the growth is showing. I did see a fungus gnat fly into the bottom of a pot so I fogged the room out with DE powder. So fucking tired of seeing these assholes. I'm positive they're from houseplants upstairs and from outside. I'd like to start buffering coco for transplanting but I'm worried the wet substrate will attract more of these dickheads.
