If ur runoffis 5.8 you can go in with 7.0. What us ur ppm
Not sure I donāt have anything to test for it.

Need to get a tds meter

You need distilled water to do a slurry test. RO will do in a pinch but it has to be ultra low ppm and contain no carbonates.

What do you mean by this? Are you doing a soil slurry test or a run-off test.

Soil slurry test
I do, but once I spent like $750 on this grow I was like I have to get something back now. My other 2 autos a perfect gorilla zkittlez, and green crack. My chemdawg is the one doing bad but the first 29 days it was good.

Oh i get it my friend its an expensive hobby getting set upā¦ im in around 1k so far lol. But a tds meter is cheap on amazon and will save you a lot of headaches. Remember no 2 plants sre the same even if the same strain. One might be a nute hog and the other barely eats. Im glad your other 2 plants are doing good. But we really need to get ahead of the problem with the one plant. So untill you get the tds pen lets flush and keep checking runnoff ph. It might take 3 to 5 times the size of your pot of water to do it. So if your in 3 gal pots put at least 9gal into it. Collect some runnoff at that point and check phā¦ we jeed to get it between 6.5 and 6.8. So your not too far off. When you flush id use ph whater at 6.8 it will bring it down slowly but gives a lil more controlā¦ then when we get that set we let it dry and then top dress with just the gaia green

OK. Personally, I donāt know how soil is pulled from the center of a massive root ball in the later part of the plantās life without digging through all the roots. Iāve never asked everyone how they are doing it.

The meters for ph and ppm will pay for themselves the first harvest!

All good my wife is looking over too 
, I just put in 6.8ph water the run off is 5.62ph
I just want to say one more thing real quick @Letsgrowmj and anyone else who can lend knowledge in this area.
I too use FF soils (OF & HF) with perlite and have been working with gaia green nutes for the last 3 grows. My conditions are probably not the same as yours. For one thing, I have well water that runs anywhere from 4.8 to 5.5 ph out of the tap.
Anyway, I have been battling pH differences between in and out. I pH in at 6.3 to 6.5, it comes out 7.2 and up. I know that when I used two different āorganicā nutes, one being GG, the run-off on the GG plants came out consistently higher than the other nuted plants, all other conditions being the same. When I first noticed the issue, I began trying to drive it down putting lower pH water in (6.0) and it didnāt help. As a matter of fact, it caused more problems. Once I went back to going in with pH nearest 6.5 like I should, the other problem went away.
I am still having this problem but my plants do well. I consitently go in with 6.4 to 6.6 and I get 7.3 to 7.5 out on all 5 plants, 3 autos & 2 photos. I am going to address this issue with ammendments to my soil mix on the next round - aluminum sulfate I think I read, there are other buffers too.
Ok I started rambling. Good luck. @Mmanson1981 and @Growdoc got you covered.

And if ur actual run off is 5.62 you might just have nute lockout
If your plants are liking it then i wouldnt mess with itā¦ once again each plant is diffrent. Learn how to read the plants they will tell you what they want if you can just listen lol
