"Anyone know this deficiency"
Skill? Lol, kidding!
It's either just leaf spots from water in strong light or maybe a slight potassium deficiency.

I'm hurt bro... ahah this is my first endeavour into organics give me a break! I haven't checked leaves under a scope but I've had bugs before but not this run other then a few gnats.

Nobody know exactly what is going on with your soil. If it is that important to you, get it tested! There are a bunch of dumb-asses on here that will lead you down the wrong path and there is also a lot of ego on this website that swear that they know what is wrong... I am not talking about anyone that posted recently, I am just talking about my exp. Basic soil test for $25... I was dealing with K and P toxicity but it looked like a Mg problem.

That's sweet bro... my issue didn't cause further spots... new soil and re reading my recipe I am short a few cups of OSF. Going to do a few new beds with a slightly tweaked recipe.

OSF is nothing but calcium, that is why I think that it works well with dolomite or other rock dusts. People say that dolomite has too much Mg but if you mix OSF or egg shells, you should be good.
Exchangable Hydrogen is supposed to be between 10-15% but it is at 21%. Calcium and Mg are on the low side also.
It should be no surprise that my Ph is also low. The exchangeable Hydrogen is another way of referring to the soil acidity. OSF is 96% Calcium Carbonate and CaCO3 reacts to acid(exchangeable hydrogen) in this manner: CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O (l)... This is the $25 soil test that I am showing in the pics.

I just realized that you might not be in the U.S for the soil test...

You do a mix of lime and osf in your mix?

Dolomite lime does not have enough Calcium by it's self. I am not saying that is your problem either, I don't know what it is... Calcium(osf) plays a huge role in your soil Ph though, it raises it. OSF is 96% Calcium Carbonate.

I have my own chickens, so I use a lot of eggshells. Here is a little clip that I found, eggshells are 95% calcium carbonate but they have a little extra too.
About 95% of the dry eggshell is calcium carbonate weighing 5.5 grams. The average eggshell contains about .3% phosphorus and .3% magnesium and traces of sodium, potassium, zinc, manganese, iron and copper. If the calcium from the shellis removed, the organic matrix material is left behind.
