Low soil pH vs high water pH, what to do?

I noticed changes in color of leaves and lack of nutrogen although I've been dilligent about feeding regularly (typically feed half recommended, feed full, feed full, compost tea, flush, flush, flush). Also noticed slower growth over the past 2 weeks, so I picked up a Blue Lab pen suspecting lockout/pH. It's an older model pen but it's supposed to test water, solution and soil.

I calibrated and then tested 4 pots (soil in fabric pots), they're consistently testing between 5.2 to 5.4. My well water is showing pH as at 8.2. I used composted goat manure, coco, fox farm ocean forest, happy frog, vermicompost, mushroom compost and have been feeding with NFTG every other day per recommended dosages. I've yet to test nutrient solution, about to do that tonight, and will do again tomorrow once it's had airstone in it overnight.

The girls are in late veg, should start flowering in 3 weeks... Should I re-pot into just a basic soil and calibrate nutes? or should I flush for a week to hopefully bring soil back up since water is 8+, and then start testing/adjusting the pH of nutrient solutions every time?

Note- After adding a tiny bit of Big Foot to my bucket cloner I noticed the water dropped to 6.5, maybe this explains why cloning with plugs in a dome has been less successful for me than the bucket cloner! I think this pen is the best investment I've ever made lol.
 
bump bump

check this out
solution change in pH
1.5 gal water 8.3
herc harvest 6.9
aphrodites 6.7
zeus juice 6.5
medusa, demeter, 6.6
gaia 6.5


added 1/2 gallon of water (8.3) and it stayed the same. will adding more water raise the ph?

Your overfeeding. That lead to the lockouts and that to a pH problem.....Then you add "flushing" into the mix and you've got the soil and it's ability to self pH so out of whack.....

How much goat shit?
Did you "cook" the soil after adding that goat crap?
Now your adding nutrients to a soil that has nutrients working and you have no Idea what the value of the soil is(NPK) to adjust what you feed to the proper amounts at the right times...

1: STOP FLUSHING - at all!

2: List the NPK of EACH of those nutrient/supplements your using!!!!
A: What ones are you using and how much of each? No quality solutions with out those OK?

3: You need to make a simple bio tea or add some myco's back into the soil to rebuild the heard and help get that soil back to self pHing!

Soil, self pH's! Simply water and walk away......You water a soil and the pH swings one way. As that soil dries back out it swings back the other way again.....Natures way of making the nutrients available in the most effective way!

Hmm goat manure,,,0.55 - 0.6 - 0.3 and if I remember right, that's for fresh....If you didn't cook the soil - that's the start of everything.

Thanks for reply..
Haven't flushed at all yet. OK will not flush.
Most people who use Nectar for the Gods feed every day from what I hear, because it's plant based/near organic you can't overfeed- that's what I was told.
The goat compost had been composted and the farmer told me it typically has a low ph. I used half of this compost to half of the fox farm mix mentioned above, mixed well. The soil was pre-mixed and sat for about 3 weeks as the clones were geting bigger, repotted etc.
The goat/wood compost mix was mixed with fox farm/happy frog/beneficials mix and then put into the fabric pots.

I've been feeding: 1/2 dose, feed, feed, feed, tea, flush flush
When I don't feed 1/2, i'm feeding per recommendations: http://oregonsonly.com/feeding-schedule
I double the recipe for every gallon of water, and I usually do 2 gallons at a time for 18 plants- 12 of which are bigger than all others.
Sometimes I feed right away, sometimes I put air stones over night.

I'm using the Advanced line in late veg.
Forgot, I also use SLF-100
NPKs:
0-0.5-0, 2-5-2, 0-1-2, 0-6-0, 1-5-1

Nice report back...
First off. look at the total P value of the nutrients.....12.5, that's your problem and your not even in bloom. In veg that should be around 3-4.

Oh trust me,,,organic or otherwise. You CAN overfeed!

When adding a feed to any plant in a boosted soil or a soil containing nutrition......It's better to feed, water, feed, water....maybe less.

Don't flush soil for anything! Organic never needs a flush at all!

I can't tell for sure with out actually seeing what the plant looks like.....But there's something I gave you...

Good luck

Doc
 
Thanks for the info! So basically, feed less and that should correct it?
OH and also a microbial tea? maybe feed, water, tea, feed, water, tea sort of schedule?
I've posted some pics in case you're interested.
Thanks again!

I only did Nute pack (beneficial inoculant) yesterday and today.
Noticing some nastiness on the leaves, wondering if there's any tips/suggestions? thanks.





























 
Hey Doc
After yesterday and today watering with Nute pack, test pH.
My water pH tests at 8 and when I add nutes it's around 6.5,
Soil pH is 7 (up 2 points from 5.2 to 5.4 on Friday, does this make any sense? Is it because they're feeding?).
