Be careful making homemade CalMag supplement

VolimPicke · Jul 19, 2021

Being cheap I wanted to make my own Calcium+Magnesium supplement.
I started by dissolving egg shells in vinegar and when no more egg shells would dissolve I thought all the acetic acid was used up - but it seems I was wrong. This is one day after application.

pH meters are useful even in soil, sorry. Hopefully she pulls through.

when working with acids and bases, allways nutralise them, potassium hydroxide for candel making would have worked very nicely and a little go's a long way

You didn't make calmag you made WS-Ca. Did you dilute it properly? I've been using the same thing in my garden and Ws-CaPo on my outdoor cannabis plants without any issues.

Anything used incorrectly can cause issues.

I don't think there will be any recovery.
There was no bubbling when eggshells were added so it must be a dilution problem.
All I can do is laugh - and learn to do better next time.

I wouldn't toss it just yet. Spray it good with plain water and wait. You'll lose the fan leaves but still have new growth at the nodes.

I bought a cheap ph meter from Home Depot
My dead plants have a ph between 5 and 5.5.
I guess that did them in

They should recover with ne growth this early

No recovery from calcium overdoes

Sadly it was the pH that killed them not the Ca. So sorry that hurts.

Oh well - it was a learning experience.
Sharing so that others see what can happen.

That was a generous and kind thing to do. It's also impressive. So few people are comfortable with openly sharing their mistakes, good job.

I'm confused but that happens often. Did you use it as a foliar or did you water the plants with it?

I was under the impression that you used it as a foliar which is the typical method.

I watered the plants with the calcium solution.

I ripped out the dead plants and among the roots I saw hard white formations that crumble when squeezed.
Could this be from too much calcium?

Looks like perlite to me. Are you using perlite?

I did not use perlite.
I also do not remember seeing it in the bags of soil I bought.

Those white things in the soil look like perlite to me. That's why I suggested it

That sucks, I know I'm on a learning curve here myself but I hate to see any plants not make it.

Most commercial soils have perlite in there.
