I had a big PH problem growing in soil. It was about ph 5 and couldn't figure out why it was so low (my water is ph 7). My plants were not liking it at all. I kept getting rust spots and they were overall not in good shape. I added some dolimite lime on top of my pots and it really seems to help. It's been about 3 weeks since I started to add lime and they are much greener and healthier. My runoff is about 6.5 now.
Lol ok seems like people arnt taking me serious.
1st runoff is NOT a valid way to check your ph. Probes dont work as well. The only true way is by getting it tested in a lab, want to know whats your soils npks and ph? Send in a sample to a unuveristy.
2nd dolmite lime does NOT magically "sink" into the soil and raises or adjust ph by topdress or in water.
Not trying to say you are wrong about your plants getting healthier, but this can not be linked to your dolmite lime being top dressed. More like maybe your soil is finally balancing itself out with other biological factors.
The reaaon why i keep repeating myself is because adding dolmite to your water and or topdress is a waaste of money, but even more important it can potentially harm your soil food web.
In you must, add oystershell as a topdress, but even better, add compost or worm castings, that will pretty much solve all problems in organics
Heres a post i found that can explain why, without going into deep science academics.

I guess what you're getting at is it can raise the pH of water quickly. What I should have asked is why the Mg and Ca in dolomite lime take so long to become available to the plants?"

Carbonates are not water soluble - all the collective stoner science can't change an immutable universal law of chemistry.
If these compounds were water soluble then you couldn't possibly have mollusks, crabs, lobsters, shrimp since they're shells are 96%+ Calcium Carbonate (CaCO3) and they live in water therefore their shells would have to be made from another compound.
Stoners have tried to redefine Botany, Biology and now they're making a run at BASIC (like in it's very basic) law of Chemistry.

Still not getting it?
Dolmite is not water soluble and will not drain into the soil and magically raise ph.
