----------------------------------------------------------------------------- Day 57 (Apr 30, 2022) ----------------------------------------------------------------------------- Air: Temp: 77F (Day) / 67F (Night) Humidity: 50% (Day) / 40% (Night) Water: PPM: 650/710 Temp: 69F PH: 5.6 - Added 8ml of AN Sensizym (daily enzymes) with 500ml RO water in a water bottle, shook, and poured into the reservoir. - Added 7ml of AN Sensi Coco Grow A+B with 500ml RO water in a water bottle, shook, and poured into the reservoir. - Added mini fans on top of RDWC buckets, pointing up under the canopy. ----------------------------------------------------------------------------- Day 58 (May 1, 2022) ----------------------------------------------------------------------------- Air: Temp: 77F (Day) / 67F (Night) Humidity: 48% (Day) / 40% (Night) Water: PPM: 700 Temp: 69F PH: 5.6 - Added 8ml of AN Sensizym (daily enzymes) with 500ml RO water in a water bottle, shook and poured into the reservoir. - PPMs stayed around 700, so I didn’t give any additional nutrients today. - Dropped daytime humidity to 48%. - Humidity seems to be maintaining itself now with transpiration from plants. ----------------------------------------------------------------------------- Day 59 (May 2, 2022) ----------------------------------------------------------------------------- Air: Temp: 77F (Day) / 67F (Night) Humidity: 48% (Day) / 40% (Night) Water: PPM: 670/760 Temp: 69F PH: 5.7 - Frost is starting to shine; trichome production in full force. - Moved clip fan to under the canopy pointing up. - Recalibrated Bluelab Guardian. It was off by about 2 points. (Actual PH was around 5.5 after calibration) - Water change today, switching to bloom nutrients. Today will be the first water change of the grow. I expect a stall in the eating and drinking. I’m going out of town for a few days so I’ll be prepping the flexitank for a bit extra to fill up the top-off bucket with the nutrient solution to keep things steady. ------------------------- Flexitank ------------------------- 75 Liters of RO water (both single and two-site systems) Added 180ml of AN Sensi Bloom Coco A+B Final Values PH: 6.2 PPM: 760 Water temp: 66f (59f out of filter line - had to let it warm up before exchanging water) At first, I thought the PH of the new solution was within a safe range of the 5.7 reading, but after calibration, it was more like a 5.5. I grew concerned the PH range was too drastic. I like to keep the water changes within the range of 5 points (5.7-6.2). Anything greater can induce PH shock. I could add PH up to the live system to bring it closer to the value of 6.2, but I will have some residual solution in the system after draining and I don’t want to risk altering the PH perfect tech. I’m going with my gut and expect that PH to come down when I drop it in the system. 1. Drained system. 2. Checked roots and cleared elbow drain by gently pulling roots back into the first bucket. 3. Filled 25L into the system (top off bucket will top off to exact level set by float valve in the reservoir. 4. Filled top off bucket with remaining new nutrient solution for while I’m out of town; approx 6 gallons. I should note: 1. I think the lack of using Orca shows in the root system. 2. I miss the Flying Skull Z9 product keeping the system clean. There is quite a bit of nutrient residue compared to my last two runs. ----------------------------------------------------------------------------- Day 60 (May 3, 2022) ----------------------------------------------------------------------------- Air: Temp: 77F (Day) / 67F (Night) Humidity: 46% (Day) / 46% (Night) Water: PPM: 760 Temp: 68F PH: 6.2/6.1 Moved AC in closer to reservoirs. Seems to be working a bit better. Added 10ml of AN Sensizym (daily enzymes) with 500ml RO water in a water bottle, shook and poured into the reservoir. Added 14ml of Microbial Mass Pro 1L RO water in a water bottle, shook and poured into the reservoir. Before Dosage: PPM: 760 PH: 6.2 After Dosage: PPM: 770 PH: 6.1 Headed out of town in the morning. I’m sure they’ll be fine. ----------------------------------------------------------------------------- Day 61 (May 4, 2022) ----------------------------------------------------------------------------- Out of town ----------------------------------------------------------------------------- Day 62 (May 5, 2022) ----------------------------------------------------------------------------- Out of town - Had a friend add 5L of RO water to the top-off bucket. - Values unknown. ----------------------------------------------------------------------------- Day 63 (May 6, 2022) ----------------------------------------------------------------------------- Air: Temp: 77F (Day) / 67F (Night) Humidity: 46% (Day) / 43% (Night) Water: PPM: 750 Temp: 68F PH:5.9 - Back in town! - She looks great. Pre-flowers flipped to bud structure in the time I was away. - She is frosting up! - PPMs dropped down to the 750 range, but held steady with the top-off solution as it started out at 770.
