Got my bluelabs comb meter, calabrate it. I know that the PH of cannibis should be between 6.0 to 7.0 but what is the best range for EC, PPM and CF for cannibis? How do I measure the soil PH? Thanks in advance for the feedback .

you PH range is off. You dont measure the soil pH. Its used to measure the nutrients you feed your plants. The pH depends on what Medium your using. COCO 5.5-6.1. Soil 6.3-6.8... Do a search for cannabis pH chart. EC values depend on what stage your plants are in veg/flower. Typically vegging plants dont need high EC feedings 1EC or less. Flower 2EC or lower is what I use in soil.

Hamhead thx for the info I'll google those charts. Would I need to take EC readings if I'm growing organicly in soil and Brewing ACT tea for nuts? If I take the PH reading of the water run off after a feeding does that give me the PH of the soil?
no Organics wont measure accurately. People that grow 100% organic dont use meters. You might get a reading but it wont be something thats usable to you.

bluelab has a good probe for measureing soil PH
http://www.getbluelab.com/shop/Bluelab+Soil+pH+Probe.html
on the downside if your doing organic soil. the money you spent on that meter could have better spent on other stuff. since like hammerhead said you don't need a meter
Oh did not see that imo its useless to measure your soil ph.. if you have sick plants taking a reading of your soil can help fix it I have done it. You dont need to buy that probe just take some of the water run off to measure.

EC chart
EC chart
thanks for the info ICMAgs family.. I found this EC chart.. does this look accurate pros?
Seedlings, Early Sprouts.........100 ppm to 250 ppm--------0.2 ec - 0.5 ec
Early Vegging..........................300 ppm to 400 ppm--------0.6 ec - 0.8 ec
Full Vegetation........................450 ppm to 700 ppm--------0.9 ec - 1.4 ec
Early Blooming.........................750 ppm to 950 ppm--------1.5 ec - 1.9 ec
Full Mature Blooms..................1000 ppm to 1600 ppm------2.0 ec - 3.2 ec

thats high for me in flower.. you will have to try it and see what is best for you. I never go over 2EC in flower and 1 ec in veg....I dont feed my seedlings anything. The medium I use has plenty in it to support them until they are around 4-6" tall. These are just starting to get 400ppm...It will stay like this until I transplant to the final flowering pot..

I have a combo blue lab myself. When im doing a 80/20 organic I can measure the EC accurately. I just love what the PK13/14 does to my flowers so I use that allot and thats not Organic. Botanicares line is Organic and natural sources so I can measure that accurately as well. Just depends on what Nutrients you use. IMO the more Organics you use the better the flavor ,Aromas will be. Potency is the same weather u use chems or Organic I have not noticed any improvement in potency when using either lines of nutrients.
