Maybe. It's going to depend on what kind of nutes, water, and soil you are using. Dolomite lime is a good source of calcium and magnesium but it's kind of slow acting. Get the finest stuff you can, prilled is the best. It also raises your pH so you don't want to get too crazy with it. You also want to mix it in thoroughly! I can't stress this enough. Top dressing or watering it in ain't gonna cut it. Cal-mag has iron as well. Dolomite lime doesn't. Happy growing my friend.I've heard dolomite lime is the same as Cal-Mag which I currently use. Does that mean I can simply use the garden lime in my hydro garden instead of the cal-mag?
Thanks
Whoops! I missed that part. Ummm, I'm gonna say no, you won't be able to replace your cal-mag if you're doing hydro. Sorry buddy.In hydro?
Not so sure about that. It is basically ground up limestone and not really soluble. Not hydro soluble anyway.

fatmans Cal-MagHow would I create a solution that's not too concentrated and also in the right ratio of nutrients?
Yeah you could mix your own but seriously man, who has the time or resources to mess around with it? Cal-mag may be overpriced but there are a few brands of it which are a few bucks cheaper than botanicare's version.

Dolomite lime is fairly slow acting. Too much of it in your medium will lockout other nutrients so it's not a good idea to add cal-mag in this way. It needs to be mixed in the soil prior to planting in order to be effective. Even then it may be too slow acting for cannabis and you may still have to add some sort of cal-mag supplement. For hydro, it's utterly useless.I have been wondering the same thing about dolomite lime. I did an experiment by crushing up dolomite lime and adding it to R/O water. The R/O started off at a pH of 6.0 and began to rise. After several hours it stabilized at 7.0 (I was using aquarium drops to measure)
Unfortunately I don't have an EC meter but there did seem to be less lime crystals in the bottom of the container. Could any of the calmag dissolve and be available to plants if watered in? It really would be convenient if we could use dolomite instead of calmag plus to fix up R/O water. Why do we need nitrogen, sulphur and iron wouldn't that come from the ferts?
So is your fuckin brain
Hey Pat? Could you try to add something constructive to the conversation?

Blow me........
Sorry to resurrect this thread but it makes me laugh when i read it. Calcium nitrate and magnesium sulfate precipitate when mixed unless chelated. Don't waste your time trying to make your own cal-mag with the mix listed.
