Yellowing Leaves

[sdp07d]

I'm not sure what is going on with these plants. The leaves are yellowing between the veins and green on veins. Some pictures of the problems and pictures on my garden.

They are potted in:
Organic Substitute for Cornell Mix:
1/2 cu. yd. sphagnum peat moss
1/2 cu. yd. vermiculite
5 lbs. ground limestone
10 lbs. bone meal
5 lbs. blood meal

They also have been fertilized with Texas tomato food and haven't been watered in two weeks. We've had some rain though, but not much.

I think that some symptoms are hard to diagnose because two totally different things can cause the same symptoms. I'm in really hot south Florida and in the summer right now. I've noticed a lot of yellowing leaves and leaf damage to plants that are getting way to much sun and heat. I was confused at first because I had always read and been told that pepper plants want as much heat and sun as you can give them.
 
I've experimented with moving plants out of the sun and put them into the shade of trees or other large plants. The leaves stopped yellowing and the plants started producing fresh dark green growth.

Yellowing is a prominent sign of nitrogen defiency. It can also be caused be not having enough water, or too hot.

It's likely not a water problem because they would be droopy, and it would be pretty obvious.

A few random thoughts.
 
How long did the soil sit after liming? Did you use a wetting agent?
 
Looks like magnesium deficiency, from my extensive *choke* experience growing lots of *gag choke* different kinds of peppers.
 
Phew. Made it. All my BS almost got caught in the throat.

The soil sat for 4 weeks before potting. There was no wetting agent. What is recommended for that in the future?

I only have 2(habanero and red moruga) of my 20 plants that look like this. Ive used an epsom salt spray on the leaves for magnesium...

I don't think it is nitrogen since all the leaves are the same, not just the lower ones. I think I'll try fertilizing them tomorrow and hopefully they perk up.

I just tried hot water and aloe (tablespoon a litre/1.5%) on the new batch of sphag, haven't potted into it yet though. Hopefully taking water easier than the last batch. A clean soap (Bonners) works I've heard, I was just looking for something less... soap.
 
Anything high in saponins, yucca root powder, horse chestnut powder or such for a natural approach, with a bit of legwork for usage measurements. Or there are a myriad of chemical options common in commercial peat mixes, though many use yucca root now, I believe.
