Tomato leaf problems

MrGlen

These leaves started to yellow along the central rib and veins about a week ago. Now they have thinned to the point of translucency. A plant showing similar symptoms died last week. Both plants are isolated. Both were fed from the same nutrient mix. I am wondering if this might be sever sunburn... Mostly on account of it having appeared after I moved the plants to a location with intense sunlight. Any thoughts?

Now they are in full sun are you getting any water on the foliage when you water them? Also, what time of day do you water?

I don't tend to get water on the leaves, but they do get a bit of rain on them occasionally, when it is windy. I water in the morning, around 8 am. They are in dutch buckets, so they usually only get water once a day.
 
To clarify, they are on the corner of a terrace. They have shade for about three hours a day, I'd guess. When the sun comes out though... last week I forgot that I had left some one inch thai chili seedlings out (seeded in damp rice hull), The rice hull was dry and they were dead in an hour and a half or so. The thing is that we are currently going from cloudy to hot as heck in minutes, with the majority of most days being cloudy, so I am wondering if that means nothing is hardening off. 
 
You could be correct, as you already know Tommy leaves will burn in "severe" heat if water gets on them, but all i can suggest is make sure you water under the foliage and early as possible in the A.M so any water can dry off the leafs before the heat sets in.

Dont think i've been much help...but good luck.

No, the input is very helpful. I'm just guessing... my other guesses are something wrong with the nutes or some little critter... pretty much anything. I looked up photos of sunburn, and most of it seems to go from the outsides in, where this is from the insides out. Strange, no?Do you think it is sunburn? I've got another little one showing the same symptoms now.
 
It doesn't look like sunburn. What nutes are you using? If it isn't disease or nute burn it is probably mites. I'd suggest taking a few effected leaves from a couple different places on the plant, bringing them in and looking at them in good light with a magnifying glass if need be. 
 
I agree with you in the sense that I've never seen sunburn take on such a uniform pattern. The way the cell death appears to take the path of the leaf veins makes me think it's either internal, being nutes or disease, or a pest sucking out the life. 
Can you attach a picture of the full plant? I'd be curious to know if the stem has damage and is wilting or are all the leaves turning brown and wilting. This would be indicative of tomato russet mites or something of the sort.

I am using hydroponic nutes, something local and unbranded, at 1200 ppm. The busiest and most complete local agricultural shop stocks only the one type for vegetative growth.Things have gotten worse for these two plants.

The mite idea seems likely, with plants having gotten worse during a few rainy days. I'll have to pick up a magnifying glass and some miticide.
 
Yeah definitely check for mites. Although it's strange, new growth seems relatively unaffected and the stalk looks healthy enough.
Until then, lower your nutrients and put them somewhere where they get a little less light and have more protection from the sun. 
 
Is that a Mercedes Sprinter?

Ok. I'll dilute the solution and move them somewhere shadier. Been screwing around trying to put water droplets on my camera lens as a magnifier, to no avail. If I get some pics tomorrow, I'll attach them.
 
It is a Daihatsu Luxio, Indonesian. I pretend it is a panel van for the purposes of moving... any random thing from concrete to retail booths and stock.
