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.
does te filler from your outside bed have lime and or bone meal in itI've got some plants. Here's the specs.

if you take the 300 away from the 900 your only feeding 600 ppm that would be alright for a vegging plant,were are you at on growth,pic are worth a1000 wordsAs I said the source well water is about 300PPM.
Not sure what my feeding PPM's should be but I've measured them and they've varied between 900-1200.
Not sure why it would be way too high. Following recommended amounts and often quite less. An example would be 1 teaspoon of grow big, 2 teaspoons of tiger bloom, 1 tablespoon of big bloom, 1 tablespoon sucanat, 1 teaspoon of epson salt, 1 teaspoon liquid calcium.
300 ppm source water and all the calcium in the nutes is likely building up and raising the ph past neutral and locking the plant up.
I did quite a bit of reading today and from everything I have read nutrient buildup always causes a low PH or acidification. I've not read hardly any cases where it causes it to go basic. I suspect IT may be due to the fact that my source water is already so alkaline. Maybe my citric acid adjustments just aren't holding. Perhaps I should go with a diluted phosphoric acid solution to lower the PH of the source water. Maybe would be more stable?
RO isn't going to happen but rainwater collection could become a thing.
