----------------------------------------------------------------------------- Day 22 (Mar 26, 2022) ----------------------------------------------------------------------------- Air: Temp: 76F Humidity: 67% RH Water: PPM: 350/340 Temp: 72F PH: 6.7 - Today I changed the cooling method. I have an AC pointed at the reservoirs, but today I found a 6" hepa filter at the hardware store and placed it on an intake fan using the AC hose to bring fresh cold air inside. I figured, we have two more weeks of cold temps so there is no need to run the AC if I can draw fresh air in from outside. - Maintaining a water temp of around 70f. - Dropped Humidity to 67% setting on inkbird controller now that plants are establishing roots. ----------------------------------------------------------------------------- Day 23 (Mar 27, 2022) ----------------------------------------------------------------------------- Air: Temp: 75F Humidity: 67%/65% RH Water: PPM: 340/440 Temp: 71F PH: 6.7/6.5 - Massive inter-nodal growth overnight! - Lowered SF1000 light for a reading of 25k lux. - Dropped Humidity to 65% setting on inkbird controller. - I could top this morning, but I'll wait until the end of the day or tomorrow for a bit more growth; no need to stunt an autoflower. - Plants were fed with 10ml of AN Coco Grow to bring up the PPM to a value of 440 from 340. As always, I added nutrients to 500ml of RO water in a water bottle, shook, and added to the reservoir. Before Dosage: PPM: 340 PH 6.7 After Dosage: PPM: 440 PH 6.5 ----------------------------------------------------------------------------- Day 24 (Mar 28, 2022) ----------------------------------------------------------------------------- Air: Temp: 75F Humidity: 65% RH Water: PPM: 440/470 Temp: 68F PH: 6.6/6.3 - The fourth node was unfolding, so I chose today to top the plant. I typically top around day 21, so I chose today to help ensure a second topping by day 30. - Topped plant just below the third node. - I'll clear the lower foliage throughout the week as it recovers and begin to train the next two tops. - Added 14ml of Rapid Start @ 0.5ml/l in 300ml of RO water, added to a water bottle, shook, and dumped in the reservoir. Before Dosage: PPM: 440 PH: 6.6 After Dosage: PPM: 470 PH: 6.3 ----------------------------------------------------------------------------- Day 25 (Mar 29, 2022) ----------------------------------------------------------------------------- Air: Temp: 75F Humidity: 65%/63% RH Water: PPM: 470 Temp: 70F PH: 6.6/6.3 - New tops have noticeable growth overnight. - Will probably wait for a bit more growth before I tie down the new tops. - Cleaned some undergrowth to allow the plant to focus on new growth. Will trim the second node over the next 1-2 days to give it an attempt to avoid any stunting. - Dropped Humidity to 63% - Accounting for -2F leaf temp. Measured leaf temp with laser dot and it was 75f whereas ambient air temp is reading 77f . - Added 3ml Orca to 300ml RO water in a water bottle, shook, and added to the reservoir. ----------------------------------------------------------------------------- Day 26 (Mar 30, 2022) ----------------------------------------------------------------------------- Air: Temp: 76F Humidity: 63% Water: PPM: 470 Temp: 71F PH: 6.4 - Removed second humidifier - RH is set at 63% so it really isn't needed any longer but having it would even out the RH in the space. The fogger can maintain 63% but I'll add another humidifier if the fogger cant keep up. - Trimmed a bit more growth below the top. - Tied down new tops very gently. - Root check (see photo) A bit of nutrient grit in the air zone, expected with AN. Running Miicrobial Mass and Orca, I don't see any rot happening any time soon. I'll start some - Sensizym enzymes soon. to take care of any dead root matter now that the roots have established themselves. - Large fan leaves beginning to crinkle a bit. ----------------------------------------------------------------------------- Day 27 (Mar 31, 2022) ----------------------------------------------------------------------------- Air: Temp: 75F Humidity: 63% Water: PPM: 460 Temp: 71F PH: 6.5 - Removed remaining undergrowth below the topping - she can now focus on the growth of the top nodes. - Second nodes popping on new tops. - PPM dropped by a value of 10 overnight. - Had some power surges with a wind storm today and the heater doesn't power back on when there is a power outage. I didn't notice until late in the day because the digital clocks didn't even reset. This threw the VPD out of wack for the day as the ambient air temp was around 68f. Probably won't help the crinkled leaf issue. ----------------------------------------------------------------------------- Day 28 (Apr 1, 2022) ----------------------------------------------------------------------------- Air: Temp: 75F Humidity: 63% Water: PPM: 460 Temp: 71F PH: 6.5 - Just let her chill and kept VPD in check. - I'll probably bump the nutrients tomorrow is the PPMs drop again overnight - this shows me the first signs she is taking up nutrients. - Not lifting net pots any longer as the roots are starting to wind around the sides of the buckets. - Still filling up humidifier (fogger) nightly - until plants start transpiring on their own. - Lowered SF1000 light a bit more for a reading of 27K lux.
