ETHOS & GHSC - (Diary #9)

------------------------------------------------- BLOOM WEEK 5 (Dec 27-Jan 2) ------------------------------------------------- ___________ Dec 27 • No water ________________________ Dec 28 (2L in AM/4L PM) • 1.1 EC / 6.1 pH (AM) • Silica + CaMg only • 2.3 EC / 6.2 pH (PM) Things look good and smell good. There's a deep red tint in a lot of the flower (see slide 6). It's not that frosty yet, but I have to remember it's only day 30. A lot of big colas already, been a while since I had production like this so early. _______________ Dec 29 (2L AM) • 2.3 EC / 6.2 pH (PM) ________________ Dec 30 (8L PM) BD4 IN: 1.8 EC/6.0 pH (18c) OUT: 2.6 EC/6.2 pH (20c) BD5 IN: 1.8 EC/6.0 pH (18c) OUT: 3.2 EC/5.8 pH (20c) KT5 IN: 1.8 EC/6.0 pH (18c) OUT: 2.9 EC/5.8 pH (20c) 10P6 IN: 1.8 EC/6.0 pH (18c) OUT: 3.4 EC/5.7 pH (19c) 10P7 IN: 1.8 EC/6.0 pH (18c) OUT: 3.3 EC/5.8 pH (20c) Runoffs are ok...only a few more days until I flush with PK 14/15. There's signs of a phosphorus deficiency with pink/purple petioles, bronze spots and leaf tips, crispy, necrotic lower leaves. New growth is looking a little lighter than it should be too. The petioles might just be genetic but when I see other symptoms attached, I'm leaning towards a deficiency. The next few weeks are crucial to gain mass so the last thing we want to see is a lack of P or K. Potassium (K) will soon be the dominant nutrient and it relies partly on phosphorus for uptake. I'll probably start watering less to keep oxygen levels higher in the root zone to help keep P mobile. _____________ Dec 31 (4L) Mix: 20ml CaMg, 20ml Silica: 5 gallons water • 1.4 EC / 5.9 pH IN ___________ Jan 1 (2L) • 2.3 EC / 5.9 pH _______________ Jan 2 (12-14L) Mix: 18ml CaMg, 18ml PK 14/15: 20L water • 1.0 EC / 5.9 pH BD4 IN: 1.0 EC/5.9 pH (19c) OUT: 1.7 EC/6.1 pH (21c) BD5 IN: 1.0 EC/5.9 pH (19c) OUT: 1.6 EC/5.9 pH (22c) KT5 IN: 1.0 EC/5.9 pH (19c) OUT: 1.7 EC/5.8 pH (22c) 10P6 IN: 1.0 EC/5.9 pH (19c) OUT: 1.6 EC/5.7 pH (21c) 10P7 IN: 1.0 EC/5.9 pH (19c) OUT: 1.5 EC/5.9 pH (20c) Got a good flush done to set these girls up for the next 2 weeks. Just CaMg and PK Spike. This should handle any P deficiencies and allow them to start using stored nitrogen. My leaves seem to always be green until the end and that probably means too much N. 🌡️- 79.7F ✅ ❄️ - 64.9F 🆗 🌧️ - 57.7% ✅ ☁️ - 48.3% ✅ 📈 - 1.67 kPa ⬇️ (brief spike) 📉 - 1.02kPa ✅ 📊 - 1.28 kPa ✅ Average temperature sits around 74F and humidity averages at 54%. Had to tie up some branches on BD5 as they were starting to topple over. Nice to see some good production out of this strain. Last time it was the best smelling and tasting in the room, but the lowest yielder. There's some big colas on BD5 and 10P7, beer can size. Happy to have cuts of both. The KT still has small buds but all white pistils and appears to be starting it's stacking phase. It's crazy frosty and looks like a 9-10 week finish. May let them all go 63-70 days depending on trichomes. Not looking for a ton of amber, just don't want any clear. There's some yellow leaf tips that appeared after the last mini flush (and days of water in a row), so this is a sign of overwatering. Making more sense looking at past notes. Previous diaries where I would water VERY frequently (but underfertilizing) I'd see leaf tips yellowing and back off the EC. That's a mistake. We're not doing that again. Allowing the substrate to dry out more frequently has built up a tolerance for high EC. Next week I'll be feeding around 2.2-2.4 EC. This isn't even full strength according to Advanced Nutrients bottle directions. They ask for 4ml a litre and I'm between 2-3ml/L. Shouldn't be worried about overfeeding, I should almost be increasing the EC closer to 3. My runoffs have been fairly consistently over 3 and as high as 5.8.
