ETHOS Clones (Diary #8)

BLOOM WEEK 6 (Sept 26-Oct 2) --------------------------------------------------- We start the week by flushing all plants with CaMg/PK 14/15 @ 1.0 EC. We'll let them dry back until they're starving for food and hit them with high strength bloom feed for the remainder of the week. _________________ Sept 26 (FLUSH) Mix: 5ml CaMg/gal, 5ml PK 14/15/gal : 5 gal water = 1.4 EC (+4L) "KC1 In: 1.0 EC/6.0 pH (10L) Out: 1.7 EC/5.8 pH (23c) "KC2 In: 1.0 EC/6.0 pH (10L) Out: 1.7 EC/5.8 pH (23c) "GS In: 1.0 EC/6.0 pH (10L) Out: 2.1 EC/5.5 pH (22c) "ELB In: 1.0 EC/6.0 pH (12L) Out: 1.7 EC/5.8 pH (23c) *MC In: 1.0 EC/6.0 pH (8L) Out: 2.1 EC/5.8 pH (22c) *CG In: 1.0 EC/6.0 pH (10L) Out: 1.9 EC/5.8 pH (23c) 🌡️: 26.5c ✅ ❄️: 21c ✅ 🌧️: 59.3% ✅ ☁️: 49.9% ✅ 📈: 1.78 ⬇️ (brief temperature spike w/ low humidity) 📉: 1.01 ⬆️ (dehumidifier bucket full and was off for an hour 📊: 1.44 kPa ✅ Phew! Alright, flush is DONE! Hand watering fuckin sucks 🤣. Probably didn't need to put as much water through as I did, but now they're full of the goods and there's very little nitrogen in the mix. Runoffs are between 1.7-2.1 EC and 5.5-5.8 pH. Ranges are good. VPD is good. Noticed most of the plants have ripening pistils already (Day 36). They're all early finishers (under 60 days) so we'll see what happens this week. I'll likely let them go 9 weeks anyway because I don't mind if they go a bit narco. Once these dry out, they'll get 2.4 EC for the remainder of the week. ____________ Sept 27 🌡️: 28.5c ❌⬇️ ❄️: 21c ✅ 🌧️: 59.3% ✅ ☁️: 47.4% ⬆️ 📈: 1.85 ❌⬇️ 📉: 1.21 ✅ 📊: 1.44 kPa ✅ • No water (PM) I thought it would take days for these pots to dry but after 24 hours, the 3 gallons are light and the 5 gallons are like 75% dry. The ELB is actually pretty light too. I'll skip watering tonight but probably have to hit the 3 gallons in the morning. PAR is reading between 885 in the corners and 1300 directly under the lamp. Average of 1068 at the canopy around the lamps. ______________ Sept 28 AM • Watered 3 gallons (1L) and ELB (1.5L) • Turned off intake at lights OFF • Switched exhaust from AUTO to ON (Speed 8) • Dehumidifier to 50% • Turned AC on at 20c between 845-945 AM Humidity was in low 50's / high 40's last night (because of the dry pots) causing VPD to rise out of ideal range (1.85). I'll give them all a big feeding tonight. _________________________ Sept 28 PM (2-4L @ 20c) Mix: 1.5ml/L CaMg, 3ml/L A, 3ml/L B, 1ml/L B52, 2ml/L Overdrive = 2.6 EC (+2L) • 2.4 EC/6.1 pH 🌡️: 27.5c ✅ ❄️: 21.8c 🆗 🌧️: 56.9% 🆗 ☁️: 51.7% ✅ 📈: 1.68 🆗⬇️ 📉: 1.12 🆗 (lights off, doesn't really matter) 📊: 1.55 kPa ✅ • Only a small amount of runoff Soon as I say the VPD is in range, it goes out of range. Heat wave coming for some reason...Highs of 27-29c next week. I'm trying to decrease the lights off temperature (and temperatures overall) but it hasn't been working, and this weather is absolutely disrespectful. I'll be running the house AC (IN FKN OCTOBER!!!) so maybe that helps out. This is really the last week to bulk up the flowers so the environment is super important. Humidity below 55% is goal right now, that's been relatively easy to hit during lights on and the majority of the dark period. __________________ Sept 29 AM (1L) • 3 gallon bags only (2.4 EC/6.1 pH) There's ripening pistils all over the place. The only ones that don't really have any are the Cherry and the Grandpa's Stash. At day 40 they may even be ready at the breeder time frame of 56-60 days. That's sort of a problem because my feed schedule is built for 9 weeks of flowering. Loose plan is to feed at 2.4 EC for the rest of the week, drop the EC to 1.8 for week 7 and flush week 8. I don't think I'll need more than a 7 day flush after giving them two pretty substantial drenchings recently. ___________________ Sept 29 PM (2L) Mix: 1.5ml/L CaMg, 3ml/L A, 3ml/L B, 1ml/L B52, 2ml/L Overdrive • 2.4 EC / 6.1 pH • No runoff 🌡️: 27.2c ✅ ❄️: 21.2c ✅ 🌧️: 57.2% ✅ ☁️: 51.7% ✅ 📈: 1.77 ⬇️ 📉: 1.12 ✅ 📊: 1.38 kPa ✅ The big temperature spikes are coming from adjusting (or forgetting to adjust) the hygrometer for leaf temps so the VPD of 1.77 is inflated. I'm taking 4 degrees off the room temp sensor at lights on, and then adding it back at lights off. SUPREME pain in the ass. ___________ Sept 30 🌡️: 28c ⬇️ ❄️: 21.7c ✅ 🌧️: 57.2% ✅ ☁️: 51.7% ✅ 📈: 1.79 ⬇️ 📉: 1.23 ✅ 📊: 1.51 kPa ✅ Hosted a party last night and didn't get into the room. Those pots will be bone dry and ready to chug. _______________ Oct 1 (3-4L) Mix: 48ml A, 48ml B, 36ml Overdrive, 24ml B52, 22ml PB Tea: 5 gallons water = 2.4 EC / 6.2 pH 🌡️: 27.5c ⬇️ ❄️: 20.3c ✅ 🌧️: 58.4%✅ ☁️: 44.5%✅ 📈: 2.02❌⬇️ 📉: 1.15🆗 📊: 1.56 kPa ✅ • Small amount of runoff on some Flowers are still stacking nicely and I'm hoping they really start growing into each other making those nice long colas we all want. The trichomes are coming in thick with the slightly lower night temps. _____________ Oct 2 (2-3L) Mix: 20ml Silica, 24ml CaMg, 16 ml PK 14/15 : 4 gal water = 1.5 EC 🌡️: 26.5c ✅ ❄️: 20.2c ✅ 🌧️: 59.9% ⬇️ ☁️: 47.7% ✅ 📈: 1.83 ⬇️ 📉: 1.05 🆗 📊: 1.33 kPa ✅ Last day of week 6! A lot of ripening pistils and loads of frost. I have a feeling they'll be ready by day 60 so next week I'll drop the EC down to 1.5. I haven't grown a ton of cookie strains, but from my limited experience with them, I've noticed their feeding drops off significantly after week 6. When I would use high frequency fertigation, I could tell by the difference in runoff EC from week 6 to 7. Week 6 I would see runoff lower than my input and in week 7 (with the same strength) would be a LOT higher than the input. If these were 9 week strains, I would probably continue at this EC but these are going to be as advertised (EARLY GIRLS). The Cherry G-S-Y will be the last to finish. She looks like she's in mid-stacking phase and there's only white pistils everywhere. Next week temperature and humidity need to come down. I'm aiming for 25c / 45-55% day and 20c / <50% night. The first problem is the heat wave here doesn't end until Saturday night so I'm going to have to run the house A/C to keep things cooler. I'm also getting drastically different humidity readings from my hygrometer vs. the dehumidifier so I can't really even say if my VPD numbers are accurate. To top it off, the dehumidifier dropped off the network somehow and I can't access it remotely anymore. Still haven't done any real defoliating yet. I cleaned the bottoms up (maybe 1/4 of the way up the plants) at the start of bloom and haven't touched them since. I may take some larger interior fan leaves off just for better airflow and to lower humidity, but only if I have to.
