Can i use this Garden lime ?

[turfsire]

My pH well below six ..
Can I use this product to raise my PH in my soil. I'm growing out of 13 litre pots.

In the pictures below in the pots I have about 2 and a half inches play should I add lime and soil together and spread it.
Listed on the box ingredients
Contains:
Calcium Oxide 46% Magnesium Oxide 15%

I should of added lime at start. Noob mistake .

I can see roots at the surface of your soil so you can't mix anything in the soil without hurting your roots.Your plants look fine from what I can see but you should be using cal/mag during flowering that can be added in your water.

Hey I've been looking up on forums the granulated lime can take months because slow release where as dolomite is soluble.
Others say grind up granules and add to water.
I used the the food blender .. put in 40 grams of granules and pint of water. I became very fine muck when it went in to the 20 litre bucket of water truly mixed.
Just sitting here now wondering will I just water them. Seeing the roots also ,could I add 2 inches of soil and water with the pulverised lime

Yes you can add some soil and mix a little lime in but it will take awhile to work.

I seen this post on another forum

"BTW, garden lime is from calcitic limestone, goodstuff. Dolomite lime is from dolomitic limestone, also good stuff. Just different limestone deposits.
If it's granular, that's also ok. It is nothing but powdered limestone formed into pellets with a fast dissolving binder. Makes it easier to work with. There is no need to crush it up."
. I added the granules to the blender roughly two ounces pint of water it became a paste which I added to 20 litres of water I mixed it throughly I Returned 3 hours later poured out the water and was left with lime at bottom. I'm going to leave it outside yard should be dry later tomorrow, I would think it would break up into powder. And would work like dolomite. Hoping
Tomorrow going to add to inches of soil and sprinkle some lime, this might work)

Turf'-- That box is labeled wrong somehow! CaO is super caustic, so not safe or even intended for garden use ... garden lime, agricultural lime, dolomite lime are the normal forms used, each having a slightly different formulation in terms of the Ca and Mg carbonates they have,.. dolomite is the slowest of them all, because of the slightly different arrangement of the molecules; particle size makes a big difference too... yes, they are all best used mixed into the soil, top dressing is slow, inefficient and possibly damaging if used in excess as such,... another "lime " is hydrated lime, Ca(OH)2, an very fast, powerful pH adjuster, not as nasty as quick lime, but it can certainly roast a plant if used wrong! Another problem is that even if you powder it, put it in solution, it still won't penetrate evenly into the soil, it will be filtered out by the soil, and can make a clay-like layer that messes with water penetration, nute chemistry, etc.,... all of this is unnecessary if you don't have a Ca-mg problem, and if you do, it can be solved by using a Ca-Mg product instead,... have you taken a soil pH reading yet? that's also very important , to determine if you should be raising the pH at all to begin with.. that's what limes do, beside slow release of Ca/Mg,.....

I ground the product up and convinced myself iit was dolemite.
What I done was mixed up litre of soil w/ 1 tbsn of lime well mixed together. applied it as top dressing watered it.
Looking this morning there signs of benefit no more later or tomorrow..

The grow nearly over now so hopefully it will help a bit.
I will now be aware of the importance ofor lime when I make more soil mixes
