Leaf necrosis - expert help needed

I meant you only have a hammer because you can't measure my water or environment, all you have to go on is my response. So typically it is going to be micros too much or too little. But well water has a lot of other things, even though it can pass through all filtration and still read 0 PPM. If you have grown with deep earth well water then you might understand.
 
Is your well on top of clay? Limestone?
What's the earth like underneath it?
It'd already have a heap of calmag and other minerals already.
If you knew your filter wasn't working. Why are you asking us what your problem is??
Especially since you didn't mention your well water, or filters in your original post.

Seems a little misleading to me.

You have hard water dude. Take away some calmag. Filter your well water whatever.
Treat your plants for fungus if it makes you feel any better.
But IMHO you've missed a few basics, and it's wrong to be calling someone out, who is genuinely trying to help you.

My filters worked - I always used my RO, just at one point my filters needed changing and my TDS was 3 instead of 0.

I am just trying to think of everything, and I am not calling you out. Just trying to figure a problem out. You've tried to help and I appreciate it, sorry it did not solve my issue though, just covered the basics. Now let someone else help. Thanks.
 
I see two things wrong with your grow, but I'm not an expert, just a guy that grows very healthy plants. LOL
 
Rusty spots and curled leaves are a sign of calcium deficiency.

So what are the two things you think are wrong?

Yeah, typically that doesn't affect the middle of the plant first though, like what you posted it affects the newer growth first. And all of my plants are in the same medium sharing the same reservoir but only 15% of plants are affected and it is not spreading to any other plants for weeks now.
