Pics...Potassium Deficiency or fertilizer burn?

[parah]

Do the pictures look like fertilizer burn?
These tomatoes are growing in containers similar to Raybo's instructions.
The soil is 60% peat moss, 40% perlite. I added time release fertilizer pellets 3 months ago. I fertigate weakly weekly at about 200 TDS (total dissolved solids) with Dyna-gro Foliage pro and Pro-Tekt.

Or maybe the heavy rain last month washed out most of the fertilizer and these plants are Potassium starved. Any suggestions?

Dyna-Gro Pro-Tekt is a 0-0-3 Potassium (K2O)/Silicon (SiO2) supplemental fertilizer.

That's a Self Watering Container, where are the nutrients going to leach too?
"The soil is 60% peat moss, 40% perlite", that's it? No Dolomite or Bark Fines?
just askin, I'm have no expertise with SWC's,

Yes, some Dolomite, but 6 months ago.
Yes, some Bark Fines, but not much because the smallest I can get is about .5 inch. Mostly German peat moss and perlite.

Looks like fertilizer burn to me. But also looks very similar to wind or sun burn!

I though it might be Sun burn too, but I couldn't find any tomato leaf pictures with similar discoloration.

And the same plant (Earl's Faux) in the next container doesn't have the problem.

Yes, the soil mix was very waterlogged for weeks. The monsoon rains were heavy enough to overflow the drain holes. The soil was "rain washed" for 2 weeks. So how could it be over fertilized?
But if it is under fertilized why is there enough nitrogen.

Is this some kind of blight?
It doesn't match any tomato disease photos I studied.

The closest match I can find is Potassium Deficiency.

But gave them extra Pro-Tekt (potassium suppliment) 10 days ago and have not noticed any improvement.

I am very puzzled.

I was able to look up the "dyna-grow foliage pro", says it's a 9-3-6, which is a higher ratio of nitrogen than what I would recommend for you. A fertilizer with a 1-1-1 ratio would be much better, or even better yet, a 1-2-2 ratio. What are the timed released fertilizer tablets? What is "Pro-Tekt"?
