So you want the ppm?
I use composted amendments and tea, so I can check the ppm, but I don't know if that'll help.
I can check the Calmag if you want.

What pH down you use?

that won't help for the K. i forgot you said you used tea.
but sure the cal/mg numbers would help

GH ph down. phosphoric acid right? i'd have to look at the label to double check

Ya, gypsum is insoluable. If you use phosphoric for your pH down, you could add CaCO3 and the acid would neutralize the carbonate and you'd be left with calcium phosphate. If you use H2S04 you'd get a gypsum precipitate.
You can use calcium gluconate as well. Which is I think the most soluble of all 3 types.

i use well water which has a decent amount of carbonates. i could look at my last well report to see the actual numbers.
that's why this grow was weird to have Ca issues. never had them before with well.

Cal mag as I've been using barebones without issue is 118ppm with a 26ppm base in one gallon of water.
The higher dosage that I was using with issue came out to 233ppm, same base water.

would there be another source of Ca in your tea or compost do you think?

Ya, I use tap too, MB as well. I really think its too much Ca, but only one way to find out. Excess Ca blocks almost everything. I could very well be wrong though.
The GH CalMg is not just calcium nitrate and Epsom, its only required to have the amount of Ca-Mg in the bottle that they advertise as. If you look at the color ect, its not just 2 salts in RO water. I think it's a way they shield from "reverse engineering." Anyways I guess my point is, that when ppl are adding Ca-Mg they may be feeding the plant something they're unaware of and blaming/praising Ca or Mg.
Why I'm transitioning to mixing my own salts... No more BS, ill know exactly whats going in..

How much calcium is in bananas? I don't know how to measure that.
I use a rotting banana compost, strictly banana slurry mixed with coco, to make the tea. Figured that out after a finicky blueberry strain that was a K whore. Gets filtered once before it goes in to reduce the amount of particles.
In my regular compost, I have eggshells.

What I gathered from that, would be more Ca would better, right? Sorry, not hip a scientific language. Think I grasped it, though the chemical compositions of the Ca could effect it, right?
Also, didn't see a mention of LED. They grow just fine under HPS and T5s.

Wtf? Kind of creeped out? What's the reason for that song?

Lmao oh just baked, I remembered from when I was young, used to love hearing the deep bass guy say "30 thousand pounds of bananas" lol just thought I'd add to the banana theme.

Lol, got it now. That's a song an old friend and I shared, but he's not around anymore. Didn't realize my post lol.
I'm stoned lol. My apologies.

Ya I didn't see LED mentioned either. Seems like the extra Ca makes the plants taller and develop more cellulose, more fiber, stronger stalks, firmer fruit, but said that it diminished yield as well.

That's pretty surreal, I really like Chapin but not known to many ppl to even know of him lol, even though he's kinda an oldie I just like the stories..

Yea, that's what I gathered as well.
Basically, my running theory is that LEDs increase the potency or uptake of K in the plant, reducing overall Ca values taken in.
I don't have the room to set up a proper testing ground at the moment, but I would like to evaluate this further.

2 boys, an old international pickup, and a dirt road... Wow. Takes me back lol.
That's why I was creeped out lol.
