Strain; Type, Bag seed, ILGM… name of strain: Clone, Sour D
Age from Sprout: Day 60 from transplant
*** Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pot:* 150L DWC Res using only Aqua Flakes A&B and Hydroguard.
How often do you water and how do you determine when to do so? Topped off daily as the plants consume 3-6 gallons of water per 24 hours. Using a 7 step RO system with the last step UV treating.
PH of water and runoff or solution in reservoir: 5.7 at night, 5.8 during the day. Slight drifts to 5.6 all the way to 6 at times.
What is strength of nutrient mix? PPM BlueLab 720, TrolMaster 450ppms. Continuous readings.
Indoor or Outdoor: Indoor 5x5 tent
Light system, size and height from plants: Growers Choice ROI720 at 80% power. 36” from canopy currently.
Temps; Day 77-80f, night 72-75f
Humidity; Day, Night 45-60%
Ventilation system; 400cfm exhaust fan with carbon filter, 4 clip on fans
AC, Humidifier, De-humidifier: 10kbtu ac unit, humidity control available
Co2; No, however I am tracking ambient national Co2 levels in the tent. As the plants have gotten bigger, the levels have actually decreased significantly. During Veg the Co2 averages 800ppms with tent closed. Now, 2 weeks into 12/12 and the ppms drop as low as 400 with tent closed. Opening the tent and circulating the room helps keep the levels around the 600 range. No added Co2 though. Unless I find it won’t hold well above 400.
Devices: BlueLab guardian ph and ppm probes, Trol masters ph and ppm probes for redundancy. The probes are however completely encapsulated in the roots. I normally calibrate the probes every week, when changing the Res, however a few weeks ago the probes would not come out. As long as both are close to my desired value I think I’m okay ?
Water temp never above 67f
Complete Res changes every 7-10 days maximum
VPD .9-1.3
Leaf temp: 72-76f
Lux at canopy 35,000
Plants were at 1200ppms BlueLab during the last week of Veg. Each and every day throughout the ENTIRE veg cycle the Ppms on both meters dropped by about 30-100 points per day. The ph was rising with this number, and the plants haven’t drank less than a gallon of water per day since rooted. So no uptake issues.
I would raise by 50ppm every time it dropped atleast 50ppm in 24hrs.
Until it reached 1200 BlueLab, 800 TrolMaster. Then the ppm began to rise and ph started to drop. I attempted to dilute with water, and ended up well below what the plants were up taking during veg and before the change in feeding.
They were eating the 700/400 ppms in week 3 of Veg. And ppms were dropping like crazy then, with rapid growth everywhere.
Now we are 2 weeks into 12/12 and at a lower ppm and the ppms are steady finally again at 450/720. Yesterday they drank 6 gallons of water, and the ppm and ph remained exactly the same.
This is good??
However why the light green growth/spots?
It looks just like TMV even though I know there is no confirmed cases.
Plants are not slowing down
Pistols showed on day 11-12 of 12/12
Any advice? Any recommendations? Any improvements to be made ??
Thank you all.
