disease-pests Couple Different Leaf Issues

[Ronin]

Hi,
I'm have two different leaf issues with a few of my plants and want some opinions on what they might be.
 
Here is number 1:

This is happening to all 3 of my Ring of Fire Plants. I saw someone on Reddit with this same issue and other people were saying that his grow lights were too close. Is it? Or have I been over-watering?
 
Here is issue 2:

This is happening to one of my Scotch Bonnets. Could this be a calcium deficiency?

The top one is canoeing and has transpiration issues.  That's more likely to be lighting related, though the efficacy of the root system could figure in.
 
The second one looks like a watering issue.  Highly unlikely to be calcium related.
 
That's my $0.02.

I'm seeing this (canoeing) on some of my hydroponic peppers as well. 
 
The best resource I could find online confirms what CD has already mentioned:

Upwards curling is caused by your environment. - probably:
Wind burn
Lights being too close
Not enough air exchange
The problem could even be caused by all 3

 
In my case, the issue seems to be primarily caused by the lights being too close and not enough air exchange.
 
To mitigate, I've raised the lights a few inches, and I'm running a fan for a few minutes a day to improve air circulation. What is not mentioned though, is if the affected leaves will return back to normal or if they will keep this cupped up shape and only new growth will be normal.
