So last week while doing a slurry test I noticed my ph in soil was 5.2-5.5 . So after asking around in this forum I decided to water with molasses theŃ ph’d to 7.0 ( took a lot of ph up) after giving it to my plants i noticed that 2 of my plants started getting rust spots ( found out because ph fluctuation) so after looking up some info I found dolomite lime as an amendment as a solution. I just got this line from amazon but it’s really fine. I put a little in water and mixed it then checked the ph it went up 3 points (from5-8 ph) now I’m scared to use this shit anybody try this brand to increase soil ph?
Anyone try this lime?

There's nothing wrong with that brand.

I'm not sure. I use oyster shell flour to raise soil pH instead.

Well Im not sure if topdressing is going to help swift in this case. Its also creating different pH levels inside the pot, and different nutrition ratios... lime needs to mixed with and into the soil very well. Cant you just flush with the right solution until you are at your desired values?
People keep telling me that u can’t do that to raise soil ph I watered with 7.0 ph and got rust spots on my plant from ph fluctuation
Lol according to ur name I should have the answer

pH 7.0 is neutral, if you want to change the acidic milieu go alkaline.
The flush doesnt take away whats IN the soil. But the dissolved H+ will be washed away.
