LEGEND: 🌡️- Temp High ❄️ - Temp Low 🌧️ - Humidity High ☁️ - Humidity Low 📈 - VPD High 📉 - VPD Low I have to start the week by giving a BIG shout to @FrontRowAG_BrianG If you aren't following this man, I highly suggest you do so. Wealth of knowledge and some eye popping, jaw dropping diaries. WATCH THE VIDEOS! I put mosquito dunks (lil bits) in my standing water buckets just as a safeguard against any eggs or larvae. Picked up a bottle of AN's B-52 and added that into to the feed schedule. I turned off one of the lamps in favor of all 6 under one lamp at full power. Really no point in wasting the hydro and spacing them out this early. Going to continue with the simulated sunrise/sunset by turning the lamp down to 60% two hours before lights off, and back up to 100% two hours after lights on. End of Week Goals: 1- Raise EC from 1.3 to 1.7 ✅ 2- Maintain plant canopy height (LST)✅ 3- See an improvement/elimination of gnats✅ 4- 2nd topping 5- Removing all the lower-inside growth tips ✅ 6- Raise temps ✅ I want to have everything in order to ensure a smooth transition to bloom next week. Aug 15 No watering. I've increased the lights on temperature to 28c/78F and the humidity still sits between 55-65%. I had a thought about the leaf curl I was having and after all the troubleshooting, it may have actually been TOO COLD! Waiting to see what a few days of warmer temperatures does for them. My lights OFF temperature was also too low for the amount of humidity in the room. I was probably in danger of WPM if I didn't make the changes so now lights off temps are around 23-24c. Also keeps VPD in range. Starting to feel better about this run. Watering tonight if I don't get too drunk on the golf course today. 🌡️: 27.5c ✅ ❄️: 23.4c✅ 🌧️: 62.1%✅ ☁️: 57.8%✅ 📈: 1.3 (Slightly high last few hrs of lights on) 📉: 0.95 ✅ Aug 16 PM (2-3L @ 24c) "KC1 In: 1.5 EC/5.9 pH Out: 1.4 EC/5.9 pH (22c) (-0.1 EC)✅ "KC2 In: 1.5 EC/5.9 pH Out: 1.1 EC/5.9 pH (22c) (-0.4 EC)✅ "GS In: 1.5 EC/5.9 pH Out: 1.5 EC/5.9 pH (22c) (--EC--)✅ "ELB In: 1.5 EC/5.9 pH (3L) Out: 1.5 EC/6.0 pH (22c) (--EC--)✅ *MC In: 1.5 EC/5.9 pH Out: 1.2 EC/6.0 pH (22c) (-0.3 EC)✅ *CG In: 1.5 EC/5.9 pH Out: 1.0 EC/6.0 pH (23c) (-0.5 EC)✅ 🌡️: 27.7c✅ ❄️: 23.4c✅ 🌧️: 65.4%✅ ☁️: 58.6%✅ 📈: 1.27 (Slightly high last few hrs of lights on) 📉: 0.99 ✅ Hungry girls for the most part. Will do another fertigation or two at 1.5 EC and move up to 1.7 end of week. As much as I want to flip to bloom next week, I'm thinking another week of veg will get them a bit beefier. Aug 17 (1L @ 5.8 pH / 24c) Mix: 8ml A, 8ml B: 4L water = 1.8 EC (+2L water = 1.5 EC) No runoff on this event. Not entirely shocking as I boosted temps the last few days. VPD is actually really good for most of the day, with the exception of about 4 hours at the end of the light period. Temperatures stay in the high 70's/low 80's but humidity will drop from low-mid 60's to mid-high 50's (just outside of the ideal range). This concept is relatively new to me so I'm not going to do TOO much to correct that. With my day temperatures around 80F I need humidity at 60% minimum and I'm in the 57/62% range. So close. I may just lower day time temperatures a hair and that may do it. Lights off VPD is pretty much bang on now that I've boosted temps to 74F. 🌡️: 26.7c✅ ❄️: 22.6⬆️ 🌧️: 68.1% ✅ ☁️: 56.2% ⬆️ 📈: 1.22 ⬇️ 📉: 0.9 ✅ Aug 18 PM (1/2-1L @ 24c) Mix: 8ml A, 8ml B: 4L water = 1.8 EC (+2L water = 1.5 EC) • No runoff 🌡️: 27.5c✅ ❄️: 23.6c ✅ 🌧️: 64.8% ✅ ☁️: 55.3%⬆️ 📈: 1.17 ✅ 📉: 1.1 ✅ Another fertigation without runoff. Although KC/GS had a very small amount in the catch dish. Wondering if I should let it dry out for a day. Getting some low humidity towards the end of the light cycle and that raises the VPD for the last 4 hours or so. I'm going to set multiple starts and stops on the exhaust fan timer to allow humidity to build/drop when needed. Aug 19 • No water 🌡️: 27.9c🆗 ❄️: 23.3c⬆️ 🌧️: 62.7%🆗 ☁️: 56.5% 🆗 📈: 1.32⬇️ 📉: 1.17✅ Had a busy day and didn't get into the room. Humidity is still a little low for the light period and a bit high for the dark period. The dehumidifier spikes the temps up near 26 so running the intake with it should keep it down. Big water tonight and runoff test. See how they handle two days of light watering and a full day off.

First runoffs out of the bags were about 2.2-2.4 EC. After draining out, the numbers were a lot closer to base. I decided to run another liter through them to try to drop the pH a bit. Runoff pH is high across the board but I'm not sure how much I should care about that. A lot websites say the runoff pH doesn't matter because you're replacing it with a new pH'd solution. I feel like it matters though. Chime in if you know how concerned I should be with runoff pH rising, even though I'm dropping the solution pH. Curious. I took another cutting from the GS and two from CG. I've got 2 cuts (KC/ELB) already showing roots so I'll be buffering more coco at some point this week. Aug 21 PM (1/2-1L @ 1.8 EC/5.6 pH/22c) Mix: 12ml A, 12ml B, 7ml Tea: 6L water = 1.8 EC • New mix added to approx 2L of last one • Little to no runoff from 1L • Spaced out plants and turned on 2nd lamp 🌡️: 27.9c✅ ❄️: 22.1 c ⬆️❌ 🌧️: 65%✅ (until midnight) ☁️: 50.6%⬆️❌ 📈: 1.43⬇️ (Humidity dropped from probe on lamp) 📉: 0.81-1.02 ✅ (23-24c / 60-65%) • Probe dropped near a lamp and "boosted" the temp • Actually dropped humidity by triggering fans • Low humidity all night (50-55%) Last day of VEG. Bad luck with my temperature probe... it dropped from it's hook and landed on the top of a lamp, causing the hot sensor to activate the fans. Humidity dropped all night. We've raised the EC to 1.8, with the substrate reaching as high as 2.4 with no signs of nute burn. I'm honestly not believing what I'm seeing. This EC is scary to me because this is usually where I'd be at peak bloom. So I've been underfertilizing and not paying attention to VPD as much as I should. Hammer time.
