Hey, let me give you all the details:
Premier peat moss: roughly 65-70%
Composted soil, roughly 15-20%
Perlite: 15% maybe
The strip of fertilizer (1.5 - 2 cups) on the opposite side of the container, very similar to the basic earth box idea if not identical.
Nothing else in the box. Drainage holes are right at the bottom plate line where the mix is resting. about 5 and 1/2 inches space of water space below.

Nothing plugged up, draining fine.
Only earth box I have. Rest of the tomatoes are in the ground.
So I'm thinking...it must be a ph imbalance, or the fertilizer somehow dissolved quickly into a larger portion of the soil, making it too hard for the roots to build a wall against it. Does over fertilization cause leaf lightness like that?
My fertilizer strip is right on the edge of the container, couldn't be any farther away from the plant, but before I put the strip down, I soaked it well to settle the plants and mix.
