What strain: Blissful Wizard Method:Soil Coast of Maine stonington blend. Supersoil designed for cannabis. Target PH of 6.3 Vessels: 5 gallon Fabric PH of Water, Water in is 6.3-6.5 and runoff is 7.6 PPM/TDS :200-300 Indoor or Outdoor: mixed Light system Sun when outside and 2x HLG 260 xl's in 44 tent Temps; Day 75-85 Night 60-70 Humidity; Day, Night Variable with weather 50 - 85 RH Ventilation system; Yes 6 inch AC, Humidifier, De-humidifier, No Co2; No
I will keep this as simple as possible.
plant has been in flower for 3-4 weeks. I have fed it twice since flower, both times with 1/2 recommended dose of Advanced Nutrients as per schedule. the second feeding was 3 days ago.
Today is a water only day. I decided to do runoff tests.
After one gallon of 6.3 ph @ 200 ppm runoff: PH 7.7 @ 1400 ppm
So I decided to run 5 gallons off PH 6.4 water through in an effort to lower PH.
After 5 gallons (1 gal every 5 minutes or so) PH 7.6 @200 ppm
So, no change in PH.
Another 3 gallons, still no change in runoff… gah!!
Frustrated, I did a slurry test 1:1 soil and 6.3 PH water. results: PH 7.0 @ 200ppm
So there is nothing left in soil for nutrients, and the PH is high.
This soil is designed for cannabis, and has proven great results. It does have a target PH of 6.3. I did my due diligence. The plant itself is budding nicely and hasn’t alarmed me visually.
I’m trying to stay ahead of potential problems as I near the finish line.
As an aside: I did top dress lightly with DE 2 weeks ago for gnats. I have read DE is alkaline. I can’t see that as making such a big difference?
Please advise me, I’m going to leave her be until I hear back from some of you old pros. She’s outside for the day. The light was nice as I was “flushing” so I grabbed the Macro lens for a quick photoshoot, lol
