Sick and tired same problem

-- this is major Ca defc., looks like it's been going on for a while now,... Look at the pics in the Defc. Pic Depot here, the sticky thread section above this, and check out the pics for Ca defc.,... get Ca-Mg going ASAP...

If he is feeding 6.2 in a medium that's the same as a soil would the low ph lockout ca-mg? If so would it be a good ideal to throw more nutes if it's built up in medium from lockout?

My photos were doing the same and I done a ph test of soil and it was down around 5 even though I ph every water and feed. So I just started hitting it with tap at 7.5 ph and things corrected just by not feeding and water only.

Not trying to say it's wrong just questioning as I'm still learning, even after 5 years of growing.

so I did a ph test of the soil it tested at 5.5 so my other pen was messing me up but im pretyy new still thanks boyz for the help

Are you sure you can measure PH in soil like that?
I don't think it is a very exact way to do it. Some nutes are leached into the water more than other, P for example. Idk cause I don't measure PH in soil cause I don't believe it work like that.

I do my soil test by saturating medium until slight run off, also always water slowly and in increments. Never dump water until run off best to wet it wait 2 mins then repeat until run off.

Walk away for at the least 15 minutes then come back and slowly water a little more and catch mid run off, I prefer 30 but have done both with fairly accurate results.

This is one of those things where some believe it's okay and some don't. I myself have always used this method with better results than a soil probe.

Also to test how accurate It was I had a plant awhile ago that was having troubles, done my test with first run off without waiting. Came out 5.5 and 700 range ppm, when tested after 30 minutes wait it came back over 2000ppm, I flushed by repeating my water until run off until ppm were down around 800. But everytime I tested at the 30 minutes it was showing a ppm drop and raised ph from using straight tap for a few of the flushes. When I reached my 6.5 goal I used ro water to continue with the flush.

How did you check the soil ph? Where in the pot was the soil checked? Deep middle? Deep side? Shallow middle? I ask because the soil ph is controlled in the rhizosphere. The rhizosphere in the soil will correct the ph to its needed levels. Other parts of the soil can and usually will have a different reading. Plus, if using a soil.. It's super hard to get the soil ph down in the 5's.. You have to really TRY to do that. Most soils are buffered. So just wondering the method you used to check the ph!

This method works well for ppms if done slowly.. But it is wildly inaccurate for the soil ph. They make soil ph probes to accurately check the soil ph. Slurry test ph and runoff ph are last resorts.
