Lime is honestly a shit thing to add to soils, there's much better options that won't jack up your ph aspie.
That's if you leave it too late. I have mine in there for at least 3 months before using. It has stabilized by then.
1 tablespoon per 5 litres of soil.

Yes Aspie you do hear of or see peeps top dressing their soils with dolomite lime when they think they have problems that call for it mid grow. Pretty much a wasted exercise that one is yes ?

Yep, pointless to do it then and more likely to cause more problems than it will (supposedly) fix. It has to be done months in advance or not at all.

Sry mate but I'm going with the guy that builds soils for a living. Just being open minded, that's all

This is an article where he compares popular organic soil mix recipes that people preach, and he actually has explanations of why he recommends what he uses

I thought gypsum was only calcium no magnesium. I'm curious why he refer to it as a viable alternative for a different element?

Ahh, maybe he is comparing water retention of treated soil?

He gets his magnesium from other sources, like sea kelp, that don't affect the compaction apparently

As long as it fits your means bud

People selling stuff have a way of explaining why their products or methods are better without giving all the information

That's true, but he's giving away free information when he could easily just say "hey, buy my soil. It'll fix all your problems"

I just really want to get as educated as possible on organic growing, looking to multiple sources for info, etc. Not bashing anybody that uses lime, to each their own

But if there's even a slight chance of an issue I wouldn't do it

Feel free to disagree. If you've ever used Verve, you'll know it lacks almost everything.

I would use D/Lime than garden lime as the C / Mg ratio is closer to what's needed than G/lime. It works for me.

I knew my latest batch of compost would be lacking in both C and Mg as it was mainly horse shit and grass cuttings. It was too late to add lime of any kind, so used cal-mag when the leaves started to pale at the sides.

Not my image, but some of the leaves started to look exactly like this...



Fixed it with cal-mag.
