Cal mag recommendation?

So I hear you guys love them EPSOM SALTS for your cal mag in plants. Between those, and dolomite lime, like the one I'll mention after this excerpt, which would you recommend?

Evergro specialty fertilizer Dolomite lime is great for correcting soil PH, as well as a source of calcium and magnesium.
Lime is an important alkaline source of calcium and magnesium for your garden, mainly composed of ground limestone. Dolomite is the most often used limestone as it contains equal parts of magnesium and calcium. Lime is used to increase the soil’s pH and decrease acidity.



I'm using some junk soil with little to no nutrients, so I feel as though I'm going to have to amend it almost every step of the way. I've got three different forms of organic granular fertilizer, each with a higher NPK variable. Am I going to need to worry about pH'ing my soil at any time in the future? Again I'm not using synthetic chemicals, just 100% organic stuff.

Epsom salt contains magnesium and sulfur. Both are great for weed, but no calcium.

Don't need to PH organics as long as the soil is healthy.

Dolomite lime may not be the best choice... depending on what's in your soil... as it's a 2:1 ca:mg.

How's your water? It might have the magnesium/calcium you need.

You may want to post this in the organics section.

So if I was using Fox Farms Grow Big and Tiger Bloom, I'd need to pH my soil? What makes organics so special that they can get by without needing to pH?

Does my grow fit the definition of 'organic' by using materials that all have the OMRI label?

Ya. Those Fox Farms bottles aren't though. And I don't pH, but I also don't give it anything crazy. I try to keep the pH somewhat close to 6.5. My plain well water is like 7.8. and I don't mind it the water anywhere from 6-8. That's just how I do it. I've read different stuff about different pH affecting different microbes.

Tonight I'm gonna add some Ag-Sil that I got awhile ago. Never tried it. So I'm gonna add it, and check the pH. Trying other ways to give the plants more K.

You can get by without having to pH soil using inorganic fertilizer as well. I never pH when I'm growing in soil.

You were the one who solved my nitrogen issue, thank you for that btw.

So if I was to grow in coco coir or hydroponically, then I'd have to pH I take it?

Buy new. I'm using the PROMIX cheapo soil

Promix needs to be treated differently than an actual soil. It's more of an inert medium being composed primarily of peat although I think they have some coco based products as well. When I refer to soil I'm referring to a blend of peat, compost, forest products, earthworm castings, etc...

Is it reused soil, or do you buy new each time?

I reuse and buy if I need some. I have never messed with pH in soil except outdoors in my garden taking slurry tests and then adding lime if needed or adding elemental sulfur to lower the pH for my blueberries.

When I was growing hydro or plants growing in coco I always pH. But I never even thought about it with soil and was surprised to see so many people fiddling with or chasing runoff pH growing in soil. I always thought it was a hydro thing until I started reading some of the cannabis forums. Leave it to cannabis growers to overcomplicate anything they possibly can.

I'm trying to not complicate anything, hence the reason I nearly starved my plants lol.

So what do I need to anticipate or prepare for in the future? I'd really prefer to be prepared this time around, instead of driving my anxiety sky high because I'm seeing fall colours in June...
