Soil ph help!!!!!

I need to know my soil ph and fast!!! I have a pocket ph meter and have no clue how to obtain my soil ph with this instrument. PLEASE HELP!!! I'm looking for as many methods as I can get so I can try them all to see if they differ. and what should my water PH be?

PS I'm useing Lambert green formula components :White Sphangnum Peat
Perlite
Vermiculite
Limestone
Fertilizer Starter Charge
Wetting Agent

next time you water you plants take a bit of the water that comes out from the bottom of the pot and check PH on that = soil ph.

make sure to check in your tap water (fairly easy to look up this info) so that your PH meter shows correct values. peace

Dolomite lime? it should try to keep the pH at 7. Water I use is 6.8.

I have been watering at a ph of 6.5. and the mix in use has limestone in it. Will that do the same thing as Dolomite lime or should I go grab some???

It should work..just read up on it. Put soil in a clean glass with distilled water and shake up. Then check the pH.

Are you having issues? If so pics.

It's hard to see in the pics but the leaves are slightly yellowing and on some plants looks blotchy. Also today it seemed like the leaves are getting dry and felt like they have cracks in them or a reptial like skin.( the cracks don't actually go through the leaves to the other side)

Looks good. About ready to transplant.

Checking your runoff with your meter after you water does work.

It's about a +- error of .2-.4, especially in all organic soils. It's a more accurate method when nutes are introduced, about a +- error of .1-.2.

It will give you an idea of where you are with your pH.

As for ppm readings, in soil it's not necessary.

Get them out of those pots soon.

only direct ph of soil means anything. run-off means nothing. run-off ph = how buffered, by the soil, the water became. make a slurry of soil, and test that. as Coho said.

vermiculite is crap as pertaining to cannabis cultivation. it stays too wet. imo

I'm going to try both methods n report back ! It'll take a few days for my soil to dry out.

It may raise the ph of the medium but the runoff will stay low here my pic you can't see the color they're really perky with a ph of 5.5 runoff I'm phing my water 6.3 and these babes look happy with their 3rd day of flowering~

I experience this myself. I water with a solution at PH 6.8 my runoff can be as low as 5.3. Using a high end soil PH meter and I get 6.3 - 6.5 in the buckets. My plants are fine.

Go grab some, it cost less than $5.

I don't pH my tap water and it's ~7.1. You will do more harm with whatever you are using to change the pH of the water. The lime will correct it all on its own.
