What stage are they at. And no you want around 6.5 PH for soil.
JUST SOME HOUSEHOLD ITEMS YOU CAN ADD TO YOUR WATER FOR ADJUSTING THE SOILS PH.
OR YOU CAN BUT BOTTLES OF PH UP OR PH DOWN FROM A HYDRO STORE.

Flush with ph down, or distilld water, or you can add coffee grounds to your soil, like 1/8 cup if your using a 2 gal, slightly mix in the top 1/2 inch. Either one should lower your ph. I run around 6.8-7.2, which I think is kinda high, but its doing the job. Fert depends on what your gonna use.

Try a teaspoon of plain old vinegar to a gallon of distilled water. Let it sit for a while, then check the ph fo the water itself. Use distilled water which will be around 6.1-6.5. I would recommend slowly adjusting the ph by feeding it slightly lower ph water (around 5.8-6.0) until you get runoff of 6.5. I think 7.5 is way too high.

No need to measure the run off as it will always be much lower than the soils ph as the salts and nutes deposits come from out the lower pot holes when testing run off fluid.
Its best to use a water source thats slightly acidic (PH 6.8-7.0) and test only the soils PH and NOT the run off.
Just add the appropiate PH buffer to your water/feed and go with that and test ONLY the soils PH.
(good luck)

u need to be at 6.3 or 6.5 and fert once a week

Fert every other water not once a week.

Yes this is correct. Every time you water you should be adding nutes to the water as a mix to be used for every watering.

If you live near the Prius Mine in Sudburry Ontario it is.

Run off is a good indicator of where the soil's PH stands. If I pour in 7.o PH water and my runoff is 6.5, I know my soil is acidic and is probably sitting near 6.0. I have yet to meet a soil ph tester that I like and trust. I do however trust my Milwaukee PH meter and it only does liquids. My run off is a great indicator of what I need to do. You just have to take water PH and run off PH into consideration and determine whether you need to go up or down.
I'd love to hear your way of accurately testing the PH of soil without using a notoriously off PH test strip. I have a battery powered soil meter and it seems it ALWAYS reads 6.0. If I trusted it, I'd be poisoning my plants with too much calcium and Mg.

Liquid Ph test kits offer the grower an inexpensive alternative to the expensive test meters and give results which are accurate enough to accomplish the task just fine. Usually reading within +/- two tenths of a point (.02) of electronic meters, depending on the kit.
For the grower looking for the most accurate Ph control, there are many various electronic Ph testers available that when calibrated will give extremely accurate readings. Unfortunately for quality units, you may be looking at a higher price than you are able to pay, even the best units will suffer down time as probes go bad. Ph probes are especially prone to failure as the membrane ages, eventually drying out and failing.
The most common solution to fill the void is liquid type Ph test kit.
They're quick, reasonably accurate and very inexpensive.
Great backup in case your probe fails.
When using liquid Ph testers, there are some important things to keep in mind:
Always use a white background when looking at the color in the vial.
A non white back ground can alter the color subtly enough that you may end up being off by anywhere from a little to a lot depending on the color background being used.
Make sure that all color comparisons are done under natural light or normal household lighting and NOT HID light, as the red/blue spectrums of the light (HPS and MH respectively) will cause serious variations to the appearance of the solution, and in some cases you could be running your solution as much as a whole point above or below what it should be.

I'm with Serapis. I would never trust a soil ph meter. I'm thinking you'd be wasting your money to buy one. They are not accurate. Hell, go buy a little bottle of PH drops and test your runoff that way (about 7 bucks and as accurate as you can get as far as I'm concerned). At least they are unless you happen to be color blind, in which case I would suggest buying a 70 or 80 dollar ph meter. Testing runoff is the best way to get an accurate indication of PH. I think Serapis has given sound advice and somewhat echoed what I tried to express. Good luck.

make a 5 gallon bucket of 5.8-6.0 PH water and flush the each plant. Do this to all of them 5 gallon each and it will fix the problem and that's why I'm gonna only use rock wool for now on

I certainly could be wrong. Damned sure wouldn't be the first time, lol. I know what works for me and that's simply the best advice I can give.
