BLOOM WEEK 5 (Sept 19-25) ---------------------------------------------- Sept 19 AM (2L @ 19c) Mix: 15ml Silica, 24ml CaMg, 18ml PK 13/14 : 12L water = 1.7 EC 🌡️: 28c ⬇️ ❄️: 24c ✅ 🌧️: 54.4% 🆗⬆️ ☁️: 49% ✅ 📈: 1.67 ⬇️ 📉: 1.32 ✅ 📊: 1.48 ✅ • Runoff tested from ELB/CG : 4.7 / 4.0 EC out We've got 3 days until we let the pots dry out. Until then it's daily watering at 2.2 EC with the bloom nutrients at lights on. A few hours before lights off we'll water with Silica/CalMag at 1.5-1.7 EC. Pots are drying out faster and adding another watering event should help keep the EC lower. ____________________ Sept 20 (2L @ 20c) Mix: 36ml CaMg, 36ml A, 36ml B, 24ml Sensizym: 4.5 gallons = 2.0 EC / 6.2 pH • No runoff except CG (4.0 EC) Lower fans have some rust spots...possibly nutrient burn (rust does not transfer to fingers when rubbed), but I'm worried it's a phosphorus or potassium lockout. Maybe it's Calcium toxicity...that can produce yellow/brown leaf tips AND lock out phosphorus. Will keep a close eye on this as it's probably the worst time you could lock out those nutrients. I've increased the pH of my feed to 6.1-6.2 for the time being. All the nutrient charts I look at show those elements being most available at a pH over 6.0 and my last runoffs had pH under 5.8. Room is running hot but leaf temps seem ok. Sitting around 82-84F room temp, leaf temp is 76-80F. I'm setting my humidity based on LEAF temp, not room temp. Plants are drinking a ton and require a small watering a few hours before lights off. This is a sign of high transpiration. ______________________ Sept 20 PM (1L @ 20c) Mix: Left from the morning (2.0 EC/6.1 pH) • No runoff • Hygrometer is fucking up big time 🌡️: OFFLINE ❄️: OFFLINE 🌧️: OFFLINE ☁️: OFFLINE 📈: OFFLINE 📉: OFFLINE 📊: OFFLINE ________________ Sept 21 (2-3L) Mix: 20ml Silica, 32ml CaMg, 24ml PK 13/14 : 4.5 gallons = 1.6 EC pH 5.8 pH 🌡️: 27.8c ⬇️ ❄️: 23.6c ✅ 🌧️: 61.7% ✅ ☁️: 54.1% ✅ 📈: 1.32 ✅ 📉: 1.29 ✅ 📊: 1.3 ✅ Small amount of runoff. They get a full watering tomorrow with base nutes + additives at 2.2 EC, then nothing until the start of week 6 when I flush. ___________________ Sept 22 (6L @ 20c) Mix: 24ml CaMg, 36ml A, 36ml B, 24ml B52, 25ml Sensizym, 20ml PB Tea : 5 gal = 2.2 EC "KC1 In: 2.2 EC/5.8 pH Out: ERROR EC/5.1 pH (21c) (+??

We're talking 9.9 EC. The other half are 3.0 EC over base. Runoff pH is way low too. Not sure how concerned I should be with that. Most of what I read says it doesn't matter. If it matters, my pH is way out of range. Only a few days until the flush but I'm wanting to dump all kinds of water on them NOW!! The containers are light at 7:30 AM after getting 6L of 2.2 EC each last night at midnight. __________ Sept 23 Water only "KC1 In: 0.3 EC/7.4 pH (8L) Out: 1.9 EC/5.7 in pH (23c) "KC2 In: 0.3 EC/7.4 pH (8L) Out: 1.9 EC/5.7 pH (22c) "GS In: 0.3 EC/7.4 pH (4L) Out: 2.4 EC/5.6 pH (22c) "ELB In: 0.3 EC/7.4 pH (8L) Out: 2.3 EC/5.6 pH (23c) *MC In: 0.3 EC/7.4 pH (2L) Out: 1.9 EC/5.5 pH (21+c) *CG In: 0.3 EC/7.4 pH (2L) Out: 2.1 EC/6.0 pH (23c) • EC reader was on low battery, false readings yesterday Pulled the trigger on a light, water only flush (1/2 the substrate). The 3 gallon pots didn't need much at all (MC/CG 2L). It probably didn't even need flushing but I'll sleep good tonight. pH is back in range as well. ________________ Sept 24 (1-2L) Mix: 12ml CaMg, 12ml A, 12ml B, 10ml B52, 5ml PB Tea : 7L water = 2.2 EC • No runoff • Tied up branches on MC/ELB/KC • Tied branches away from cage on GS • Didn't see ANY gnats 🌡️: 27.4c ✅ ❄️: 22c ✅ 🌧️: 60.5% ✅ ☁️: 54.6% ✅ 📈: 1.58 ✅ 📉: 1.22 ✅ 📊: 1.4 ✅ I've decided I'm not going to dry out the pots. Reason being is the amount of perlite I have in these containers are already allowing enough oxygen to the roots. The logic behind the dry back is to get more oxygen to the roots, and I'm not having that problem. Instead, I'll just water with less volume, for no runoff, at high strength until week 6 starts, then flush. Colas are getting heavy and I had to tie a bunch of branches to the cages. Really nice aromas developing and flowers are already caked with trichomes. _____________________ Sept 25 (2L @ 20c) Mix: 18ml CaMg, 36ml A, 36ml B, 12ml B52, 12ml PB Tea : 12L water = 2.2 EC 🌡️: 27c ✅ ❄️: 22.3c ✅ 🌧️: 59.9% ✅ ☁️: 52.4% ✅ 📈: 1.32 ✅ 📉: 1.19 ✅ 📊: 1.28 ✅ ***END OF WEEK 5***
