I've got some plants. Here's the specs.
-amended FF Soil with some 40% "filler" from my outdoor raised beds
-# 5 gallon fabric pot
-Week 6 flower
-feeding FF trio, epson salts, sucanat, calcium
-temps 75-78 daytime and 59-62 nights
-RH about 50-60%
-good air circulation
-plants under CMH and HPS lights and are off the floor
-feeding PPM is usually around 900-1200PPM depending on the feeding (source well water is 300 PPM to start)
I'm getting some significant nutrient lockout. I think it's PH related. I'm adjusting my water for feedings and waterings to about 6.4-6.6. I't's HARD well water and it is untreated. It usually measures between 8.2-8.1 before I adjust it with food grade citric acid. I use about 1 teaspoon of citric acid to adjust 5 gallons of water.
These plants are losing foliage like crazy. Just every single leaf from the bottom up.
Today I measured PPM coming from runoff and it was around 1500 so I decided to go ahead and do a flush of 5 gallons of PH'd water through the pots. I ran 5 gallons through and got each plant to a PPM runoff of about 550.
BUT THE RUNOFF PH WAS ALWAYS 8.0-8.15?!?! I'm putting in 6.4-6.6 and I'm getting 8.0-8.1 even after 5 gallons run through it. WHAT THE HELL?
I realize I need to do a soil slurry test and I have a different meter for that. I plan on doing that next to see what that indicates.
There seems to be a total lack of understanding on using water that tests high PH for indoor growing. A lot of folks say they never treat their water but they've not had to grow with water so alkaline. It's very frustrating and I'd like to know what's happening.
