Thanks for the info and the quick response! I'll definitely save the lime for another use.

Lime is only added to soils that are heavy in acidic ingredients like peat and bark. It should not be added to gritty mix as it will make the mix too alkaline. This does, however, mean that the soil will not provide Ca or Mg. You should provide that either through your water supply (hard water often contains plenty of Ca/Mg), or by using a fertilizer that contains Ca and Mg (Dyna-Gro Foliage Pro 9-3-6 is a good one). Some people instead add gypsum to the soil (for Ca), and epsom salt to the water (for Mg), but I prefer one of the previous solutions.

No lime!

You want your water to be acidic. I have to disagree with Stush...municipalities generally keep the water alkaline in order to prevent pipe corrosion. My water tests out to pH 8.5 and our county water quality report shows 9.3. The ideal range for cacti and succulents is 5-6. Get a pH testing kit (they're less than $10 on Amazon). I use regular distilled white vinegar to acidify my water.

Thanks to all of you! My mix is ready! Now for all that repotting...

I got this part wrong!! Can anybody tell me what i can do with my succulents? I just repotted them yesterday in a gritty mix which i limed

You haven´t mentioned what plants you are growing. I grow mostly Mexican desert cacti and their habitat is heavy with limestone - great chunks of the stuff.

the plants are different succulents. some echeverias, 3 cacti, 2 sansevierias, mostly succulents. wouldnt they take up too much of what dolomite offers resulting in a difficulty in Fe uptake leading to chlorosis or something else?

Always best to keep plants growing in the ph of the soil they are found in. Just how to find out??? I keep my Sans in a lower ph. Don't know about the so many different kinds of euphorbias. Ones from Africa I keep in a lower ph as well. Don't know if I'm doing right or not. So far so good for the past 10 years.
