You're sure it's dolomite? There are two types of lime. Hydrated, slack or horticultural lime shouldn't be used except in rare cases. It's used in the range of 1/4 to 1tsp. Dolomite is used at 1-2 Tbsp/gal.

It's more of an "on demand" thing. As the soil acidifies the carbonates break down and into ca and mg. That process counteracts the acidification, holding the soil ph stable.

So it's a tbsp a gallon for every gallon of pot

1-2 tablespoons for every gallon of soil you mix. Mix it into the soil.

This assumes you have dolomite and not hydrated/slack/horticultural lime. If you're not sure, post details (Ca and Mg details) from the label.

Yes, that's good stuff. I got a 50lb bag of it from my hydroshop for $15. It's a blend of calcitic and dolomitic lime.

You can cultivate it into your topsoil using a fork, water in. I'd do it over 2-3 waterings, not all at once.

(It's best to mix it into the soil before planting.).

So add 1to 2 tbsp with the stuff I got like you said don't want to kill my plants, 1 is acting like I over watered her but I only water every 3 days when soil is dry up to my first knuckle

It's not the kind of thing you can use too much of. I did a test using 0 to 8 tbsp/gal. There was little difference in the ph between 2 tbsp and 8. Like I said, it just sits in the soil acting against acidification, but not increasing the alkalinity the way hydrated lime does. A buffer. (I wouldn't use 8tbsp. That may be unhealthy to a plant in other ways. But, in the 1-2 Tbsp range which is commonly used by growers, the measurement isn't critical.).

How beneficial it is may have to do with how acidic a person's nutrients are, or whether they overfeed or feed with runoff (mini flush each feeding). For example, I stopped using calmag and my nutes are now almost 1ph higher. Dolomite may not be as beneficial for me now. (I'm not in a hurry to try growing without it because, as I said, it's just a buffer that's used as needed.

Every grower's circumstances are different. When someone says "I don't need it," you have to realize there are factors may be different. From what I've seen on the forums, it's more common to add it than not. It's simple, makes it easy to use non-premium soils, mix your own premium soil, etc. You also don't have to worry whether the bag of soil has sat on the shelf too long, if the dolomite has already broken down. It's like insurance.
